| 1 | Development and application of biological technologies in fish genetic breeding显示文摘Fish genetic breeding is a process that remolds heritable traits to obtain neotype and improved varieties.For the purpose of genetic improvement,researchers can select for desirable genetic traits,integrate a suite of traits from different donors,or alter the innate genetic traits of a species.These improved varieties have,in many cases,facilitated the development of the aquaculture industry by lowering costs and increasing both quality and yield.In this review,we present the pertinent literatures and summarize the biological bases and application of selection breeding technologies(containing traditional selective breeding,molecular marker-assisted breeding,genome-wide selective breeding and breeding by controlling single-sex groups),integration breeding technologies(containing cross breeding,nuclear transplantation,germline stem cells and germ cells transplantation,artificial gynogenesis,artificial androgenesis and polyploid breeding)and modification breeding technologies(represented by transgenic breeding)in fish genetic breeding.Additionally,we discuss the progress our laboratory has made in the field of chromosomal ploidy breeding of fish,including distant hybridization,gynogenesis,and androgenesis.Finally,we systematically summarize the research status and known problems associated with each technology. | XU Kang DUAN Wei XIAO Jun TAO Min ZHANG Chun LIU Yun LIU ShaoJun | 2015 | Science China(Life Sciences)2015，58，2： | 23 |
| 2 | Establishment of the diploid gynogenetic hybrid clonal line of red crucian carp × common carp显示文摘This study investigated the gynogenetic cytobiological behavior of the third gynogenetic generation (G3), which was generated from the diploid eggs produced by the second gynogenetic generation (G2) of red crucian carp × common carp, and determined the chromosomal numbers of G3, G2×scatter scale carp and G2×allotetraploid hybrids of red crucian carp × common carp. The results showed that the diploid eggs of G2 with 100 chromosomes, activated by UV-irradiated sperm from scatter scale carp and without the treatment for doubling the chromosomes, could develop into G3 with 100 chromosomes. Similar to the first and second gynogenetic generations (G1 and G2), G3 was also diploid (2n=100) and presented the hybrid traits. The triploids (3n=150) and tetraploids (4n=200) were produced by crossing G2 with scatter scale carp and crossing G2 with allotetraploids, respectively. The extrusion of the second polar body in the eggs of G2 ruled out the possibility that the retention of the second polar body led to the formation of the diploid eggs. In addition, we discussed the mechanism of the formation of the diploid eggs generated by G2. The establishment of the diploid gynogenesis clonal line (G1, G2 and G3) provided the evidence that the diploid eggs were able to develop into a new diploid hybrid clonal line by gynogenesis. By producing the diploid eggs as a unique reproductive way, the diploid gyno- genetic progeny of allotetraploid hybrids of red crucian carp × common carp had important signifi- cances in both biological evolution and production application. | LIU ShaoJun, DUAN Wei, TAO Min, ZHANG Chun, SUN YuanDong, SHEN JiaMin, WANG Jing, LUO KaiKun & LIU Yun Key Laboratory of Protein Chemistry and Fish Developmental Biology of Education Ministry of China, College of Life Sciences, Hunan Normal University, Changsha 410081, China | 2007 | Science China(Life Sciences)2007，50，2： | 21 |
| 3 | Biological characteristics of an improved triploid crucian carp显示文摘An improved triploid crucian carp(ITCC) was produced by crossing improved tetraploids(G1×AT,) with improved red crucian carp(IRCC,),which were obtained by distant crossing and gynogenesis.The biological characteristics of ITCC,including the number and karyotype of chromosomes,gonadad and pituitary structures,phenotype,and growth rate are reported.ITCC possessed 150 chromosomes with the karyotype 33m+51sm+33st+33t.In the breeding season,both ovary-like and testis-like gonads of ITCC were unable to produce normal mature gametes.The ultrastructure of the pituitary of ITCC showed that most of the endocrine granules in gonadotrophic hormone(GTH) cells had not been released,providing endocrinological evidence for the sterility of ITCC.Compared with triploid crucian carp(TCC) produced by mating Japanese crucian carp with allotetraploid hybrids,ITCC not only retained the excellent traits of fast growth rate and sterility,but also acquired improved morphological characteristics,including higher body,shorter tail and smaller head. | CHEN Song,WANG Jing,LIU ShaoJun,QIN QinBo,XIAO Jun,DUAN Wei,LUO KaiKun,LIU JinHui & LIU Yun Key Laboratory of Protein Chemistry and Developmental Biology of State Education Ministry of China,College of Life Sciences,Hunan Normal University,Changsha 410081,China | 2009 | Science China(Life Sciences)2009，52，8： | 14 |
| 4 | The cloning of Dmc1 cDNAs and a comparative study of its expression in different ploidy cyprinid fishes显示文摘Dmc1 (disrupted meiotic cDNA) is a functionally specific gene, which was firstly discovered in yeast and then found to encode a protein required for homologous chromosome synapsis during the process of meiosis. In this investigation, we cloned the partial cDNAs of Dmc1 of diploid red crucian carp, Japanese crucian carp, common carp, triploid crucian carp and allotetraploid hybrids by using a pair of degenerate primers based on the conservative sequence of amino acids of the DMC1 protein in yeast, mouse and human. The full length cDNAs were then obtained by rapid amplification of cDNA ends (RACE). Our data showed that the full length cDNAs of Dmc1 in the three diploid fishes are all 1375 bp long, while it is 1383 bp long in triploids and 1379 bp long in allotetraploids. And despite of the variation in length, all the cDNAs encode a protein of 342 amino acids. A high homology of 97.3% of the DMC1 protein can be drawn by comparing the amino acid sequences in the three diploids, which is also of 86%, 86% and 95% similarity to human, mouse and zebrafish, respectively. A comparative study of the expression pattern of Dmc1 was carried out by RT-PCR using specific primers against the same se-quences of coding regions in different ploidy cyprinid fishes, from which it was showed that Dmc1 was expressed only in gonads of these five kinds of fishes. The expression pattern of Dmc1 in both ovaries and testes from different ploidy fishes within breeding season was also studied by Real-time PCR, and the results showed that the expression of this gene was greatly different among the three different ploidy fishes, which was the highest of triploid and lowest of allotetraploids. The histological sections data showed matured gonads of both diploid red crucian carp and allotetraploids in breeding season, although the latter demonstrated a higher maturation, and no gonadal maturation could be observed in triploids. In conclusion, we suggest that Dmc1 is specifically expressed in the period of meiosis in all the ploidy cyprinid fishes and directly related with the development of gonad in a manner of ploidy-independent way. And further, the high expression of Dmc1 in female triploids might be associ-ated with abnormal meiosis and sterility. | TAO Min, LIU ShaoJun, LONG Yu, ZENG Chen, LIU JiFang, LIU LiangGuo, ZHANG Chun, DUAN Wei & LIU Yun Key Laboratory of Protein Chemistry and Developmental Biology of State Education Ministry of China, College of Life Sciences, Hunan Normal University, Changsha 410081, China | 2008 | Science China(Life Sciences)2008，51，1： | 13 |
| 5 | Rapid growth and sterility of growth hormone gene transgenic triploid carp显示文摘Triploid carp(100%)with 150(3n=150)chromosomes were obtained by crossing the females of improved tetraploid hybrids(♀, 4n=200)of red crucian carp(♀)×common carp(♂)with the males of diploid yellow river carp(♂,2n=100).The crosses yielded transgenic triploid carp(positive triploid fish,44.2%of the progeny)and non-transgenic triploid carp(negative triploid fish). Histological examination of the gonads of 24-month-old positive triploid fish suggested they were sterile and the fish were not able to produce mature gametes during the breeding season.Morphologically,both the positive and negative triploid fish were similar.They had a spindle-shaped,laterally compressed,steel grey body with two pairs of barbells.Most of the quantifiable traits of the triploid carp were intermediate between those of the two parents.The positive and negative triploid fish were raised in the same pond for 2 years.The mean body weight of the positive triploid fish was 2.3 times higher than the negative triploid fish.The weight of the largest positive triploid fish was 2.91 times higher than that of the largest negative triploid fish.Thus,we produced fast-growing transgenic triploid carp that have a reduced ecological risk because of their inability to mate and produce progeny. | YU Fan XIAO Jun LIANG XiangYang LIU ShaoJun ZHOU GongJian LUO KaiKun LIU Yun HU Wei WANG YaPing ZHU ZuoYan | 2011 | Chinese Science Bulletin2011，56，16： | 11 |

| 7 | Formation and biological characterization of three new types of improved crucian carp显示文摘The improved tetraploids (G1×AT) were obtained by distant crossing and gynogenesis and the high-body individuals accounted for 2% among G1×AT. After mating with each other, the high-body in- dividuals produced three kinds of bisexual fertile diploid fishes: high-body red crucian carp, high-body fork-like-tails goldfish and gray common carp. The high-body red crucian carp mating with each other formed three types of improved crucian carp (ICC) including improved red crucian carp (IRCC), im- proved color crucian carp (ICCC) and improved gray crucian carp (IGCC). The phenotypes, chromo- some numbers, gonadal structure and fertility of the three kinds of ICC and their offspring were observed. All the three kinds of ICC possessed some improved phenotypes such as higher body, smaller head and shorter tail. The ratios of the body height to body length of IRCC, ICCC and IGCC were 0.54, 0.51 and 0.54, respectively. All of them were obviously higher than that of red crucian carp 0.41 (P<0.01). Three kinds of ICC had the same chromosome number as red crucian carp with 100 chromosomes. All the ICC possessed normal gonads producing mature eggs or sperm, which was important for the production of an improved diploid population. Compared with red crucian carp, all the ICC had stronger fertility such as higher gametes production, higher fertilization rate and higher hatchery rate. Three types of improved diploid fish population were generated from the three kinds of ICC by self-crossing, respectively. The ICC can serve as ornamental fish and edible fish. They are also ideal parents to produce triploids by mating with tetraploids. The new ICC plays an important role in biological evolution and fish genetic breeding. | WANG Jing, QIN QinBo, CHEN Song, LIU ShaoJun, DUAN Wei, LIU JinHui, ZHANG Chun, LUO KaiKun, XIAO Jun & LIU Yun Key Laboratory of Protein Chemistry and Developmental Biology of Ministry of Education of China, College of Life Sciences, Hunan Normal University, Changsha 410081, China | 2008 | Science China(Life Sciences)2008，51，6： | 8 |
| 8 | Hierarchical representation of on-chip context to reduce reconfiguration time and implementation area for coarse-grained reconfigurable architecture显示文摘In reconfigurable system,fast reconfiguration and small size of configuration contexts are strongly required to enhance the processing performance and reduce the implementation overhead.In this paper,a hierarchical representation of contexts for CGRA called HCC is proposed to satisfy the above requirements.In HCC,the contexts are constructed in a hierarchical fashion to thoroughly eliminate the repetitive portions of the contexts,not only reducing the overall contexts storage size,but also alleviating the contexts transportation overhead.The fast context-indexing mechanism is proposed in HCC to achieve high configuration speed,since the hierarchically organized contexts can be located and accessed conveniently.HCC has been verified in a reconfigurable processor called REMUS HP.Owing to HCC,when implementing H.264 decoding on REMUS HP,76.67%of the overall contexts are reduced compared with the traditional non-hierarchical one;and the configuration speed is averagely 23×increased compared with the latest reported optimized configuration mechanism on Virtex-4 FX60.REMUS HP is implemented on a 48.9 mm2silicon with TSMC 65 nm technology.Simulation shows that 1920×1088@30 fps could be achieved for H.264 high-profile decoding when exploiting a 200 MHz working frequency.Compared with the high performance version of XPP,the performance is 181%boosted. | WANG YanSheng LIU LeiBo YIN ShouYi ZHU Min CAO Peng YANG Jun WEI ShaoJun | 2013 | Science China(Information Sciences)2013，56，11： | 7 |
| 9 | Genomic variation in the hybrids of white crucian carp and red crucian carp: evidence from ribosomal DNA显示文摘In this study, we conducted a cross of white crucian carp(♀)×red crucian carp(♂)(WR), and characterized the morphology, reproduction and genetics of the progeny. Different from parents, WR with the gray color showed the hybrid morphological traits of both parents. WR possessed normal gonads producing mature eggs or sperm, and exhibited high fertilization rate(90.2%) and high hatchery rate(80.5%), which contributed to produce and enlarge the population. WR with the same DNA content as parents was a diploid fish with 100 chromosomes(2n=100). Amplified ITS of 45 S r DNA, in WR the sequences consisting of 884 bp bases of the entire ITS-1 region, 5.8 S region, and entire ITS-2 region. The sequences showed high similarity between WR and its parents and leaned towards male inheritance. In WR, NTS of 5S r DNA consisted of three length types with total 654 bp bases. From sequence analysis of NTS, WR shared 94.2% and 95.1% similarities with their female and male parent, respectively. Sequence analysis of ITS and NTS revealed that there existed recombination and variation in the hybrid progeny, which was the genetic base for adaptation and speciation. In conclusion, we obtained WR from hybridization and it exhibited hybrid traits in morphology and variation in genetic composition showing essential difference with its parents. The obtainment of WR has important significance in fish genetic breeding. | WANG Jing XIAO Jun ZENG Ming XU Kang TAO Min ZHANG Chun DUAN Wei LIU WenBin LUO KaiKun LIU Yun LIU ShaoJun | 2015 | Science China(Life Sciences)2015，58，6： | 7 |
| 10 | An efficient VLSI architecture of speeded-up robust feature extraction for high resolution and high frame rate video显示文摘This paper proposes a VLSI architecture of the optimized Speeded-Up Robust Feature (SURF) algorithm. The SURF algorithm which is widely used in computer vision applications, locates interest points (IPoints) and extracts feature descriptors based on the surrounding gradients. In the proposed approach, the SURF algorithm is modified to make it more suitable for hardware implementation with little accuracy lost compared to OpenSURF, an open source software implementation based on OpenCV. The resource cost and throughput gain are balanced. Word Length Reduction (WLR) is adopted to compress the integral image and reduce the occupied memory resources. The orientations and the feature descriptors of the IPoints are calculated in a more efficient way, which significantly reduces memory accesses. Moreover, the operations are pipelined both in and among the proposed hardware modules. This VLSI architecture has been validated on FPGA (Xilinx Virtex-4 XC4VLX80), which is able to detect IPoints and extract SURF feature descriptors in a VGA (640 × 480) 64 fps video input with a 96 MHz working frequency while dissipating 1.278 W. This throughput is more than double of the ones reported in the latest literatures. | ZHANG WeiLong LIU LeiBo YIN ShouYi ZHOU RenYan CAI ShanShan WEI ShaoJun | 2013 | Science China(Information Sciences)2013，56，7： | 6 |
| 11 | Establishment and application of distant hybridization technology in fish显示文摘Hybridization is widely used. However, for a long time, systematic theories and technologies related to hybridization in fish have been lacking. In this study, through long-term systematic research, we investigated and obtained the main rules regarding inheritance and reproduction related to fish distant hybridization. Furthermore, we established one-step and multistep breeding technologies that were suitable for interspecific hybridization and intraspecific hybridization. Simultaneously, we used these two breeding technologies to produce a batch of diploid fish lineages and tetraploid fish lineages and improved fishes. In addition, we widely discuss the methods, technologies and results of hybridization breeding, referring to the domestic and foreign literature on fish hybridization. We hope that this paper will be beneficial for the research and application of fish hybrid breeding. | Shi Wang Chenchen Tang Min Tao Qinbo Qin Chun Zhang Kaikun Luo Rurong Zhao Jing Wang Li Ren Jun Xiao Fangzhou Hu Rong Zhou Wei Duan Shaojun Liu | 2019 | Science China(Life Sciences)2019，62，1： | 6 |
| 12 | Co-doped IT-M0S2 nanosheets embedded in N,S-doped carbon nanobowls for high-rate and ultra-stable sodium-ion batteries显示文摘Despite various 2H-MoS/carbon hybrid nanostructures have been constructed and committed to improve the performance for sodium-ion batteries(SIBs),they still show the limited cycle stability due to the relatively large volumetric expansion during the charge-discharge process Herein,we report the construction of cobalt-doped few-layered 1T-MoS2 nanosheets embedded in N,S-doped carbon(CMS/NSC)nanobowls derived from metal-organic framework(MOF)precursor via a simple in situ sulfurization process.This unique hierarchical structure enables the uniformly dispersed Co-doped 1T-MoS2 nanosheets intimately couple with the highly conductive carbon nanobowls,thus efficiently preventing the aggregation.In particular,the Co-doping plays a crucial role in maintaining the integrity of structure for MoS2 during cycling tests,confirmed by first-principles calculations.Compared with pristine MoS2,the volume deformation of Co-doped MoS2 can be shrunk by a prominent value of 52%during cycling.Furthermore,the few-layered MoS2 nanosheets with 1T metalic phase endow higher conductivity,and thus can surpass its counterpart 2H semiconducting phase in battery performance.By virtue of the synergistic effect of stable structure,appropriate doping and high conductivity,the resulting CMS/NSC hybrid shows superior rate capability and cycle stability.The capacity of CMS/NSC can still be 235.9 mAh·g^-1 even at 25 A·g^-1,which is 51.3%of the capacity at 0.2 A·g^-1.Moreover,the capacity can still remain 218.6 mAh·g^-1 even over 8,240 cycles at 5 Ag·g^-1 with a low decay of 0.0044%per cycle,one of the best performances among the reportec MoS2-based anode materials for SIBs. | Peihao Li Yong Yang Sheng Gong Fan Lv Wei Wang Yiju Li Mingchuan Luo Yi Xing Qian Wang Shaojun Guo | 2019 | Nano Research2019，12，9： | 6 |
| 13 | The formation of improved tetraploid population of red crucian carp×common carp hybrids by androgenesis显示文摘Bisexual fertile diploid androgenetic individuals (A0) (2n=100) were formed by androgenesis. In this way, the diploid spermatozoa from male allotetraploid hybrids (AT) (4n=200) of red crucian carp (Carassius auratus red var.) (♀) × common carp (Cyprinus carpio L.) (♂) were used to fertilize the UV-treated hap- loid eggs of goldfish (Carassius auratus), and living androgenetic diploid fish were developed. The A0 became sexually mature at the age of 2 years, and they fertilized with each other to form their offspring (A1). In this study, we observed the chromosomal number, gonadal structure and appearance of A1 fish. The results are as follows: (1) In A1, there were 85% tetraploids (A1-4n), 10% triploids (A1-3n) and 5% diploids (A1-2n), suggesting that diploid A0 could produce diploid gametes. It was concluded that the formation of diploid gametes generated from diploid A0 was probably related to the mechanism of pre-meiotic endoreduplication. (2) Among A1, only A1-4n possessed normal ovaries and testes. The mature males of A1-4n produced white semen. Under the electron microscope, the head of diploid sperm generated by A1-4n was bigger than that of haploid sperm generated by red crucian carp. In the testes of the A1-4n, there were many mature normal spermatozoa with a head bearing plasma mem- brane and a tail having the typical structure of '9+2' microtubules. Between the head and the tail, there were some mitochondria. The ovaries of A1-4n developed well and mainly contained II, III and IV-stage oocytes. The IV-stage oocytes were surrounded by inner and outer follicular cells. The micropyle was observed on the oolemma of follicular cells. There were abundant yolks and plenty of endoplasmic reticulum in the cytoplasm of IV-stage oocytes. Because A1-2n and A1-3n were distant crossing diploid hybrids and triploid hybrids respectively, they possessed abnormal gonads, and no mature semen and eggs were observed. (3) Compared with allotetraploids, the A1-4n fish not only had advantages such as fast growth rate and strong resistibility but also showed some new good performances such as high ratio of body width to body length, smaller heads and shorter tails. These results indicated that an- drogenesis could produce bisexual fertile tetraploids and improve the shape of allotetraploid hybrids as well, which will be of great significance in both the cell genetics research and fish breeding. | DUAN Wei QIN QinBo CHEN Song LIU ShaoJun WANG Jing ZHANG Chun SUN YuanDong LIU Yun | 2007 | Science China(Life Sciences)2007，50，6： | 4 |
| 14 | Mass transport deposits and processes in the north slope of the Xisha Trough,northern South China Sea显示文摘Triple mass-transport deposits(MTDs) with areas of 625, 494 and 902 km2, respectively, have been identified on the north slope of the Xisha Trough, northern South China Sea margin. Based on high-resolution seismic reflection data and multi-beam bathymetric data, the Quaternary MTDs are characterized by typical geometric shapes and internal structures. Results of slope analysis showed that they are developed in a steep slope ranging from 5° to 35°. The head wall scarps of the MTDs arrived to 50 km in length(from headwall to termination). Their inner structures include well developed basal shear surface, growth faults, stepping lateral scarps, erosion grooves, and frontal thrust deformation. From seismic images, the central deepwater channel system of the Xisha Trough has been filled by interbedded channel-levee deposits and thick MTDs. Therefore, we inferred that the MTDs in the deepwater channel system could be dominated by far-travelled slope failure deposits even though there are local collapses of the trough walls. And then, we drew the two-dimensional process model and threedimensional structure model diagram of the MTDs. Combined with the regional geological setting and previous studies, we discussed the trigger mechanisms of the triple MTDs. | QIN Zhiliang WU Shiguo WANG Dawei LI Wei GONG Shaojun MI Lijun SPENCE George | 2015 | Acta Oceanologica Sinica2015，34，9： | 4 |
| 15 | Spatial and Temporal Distributions and Sources of Anthropogenic NMVOCs in the Atmosphere of China:A Review显示文摘As the key precursors of O_(3),anthropogenic non-methane volatile organic compounds(NMVOCs)have been studied intensively.This paper performed a meta-analysis on the spatial and temporal variations of NMVOCs,their roles in photochemical reactions,and their sources in China,based on published research.The results showed that both nonmethane hydrocarbons(NMHCs)and oxygenated VOCs(OVOCs)in China have higher mixing ratios in the eastern developed cities compared to those in the central and western areas.Alkanes are the most abundant NMHCs species in all reported sites while formaldehyde is the most abundant among the OVOCs.OVOCs have the highest mixing ratios in summer and the lowest in winter,which is opposite to NMHCs.Among all NMVOCs,the top eight species account for 50%−70%of the total ozone formation potential(OFP)with different compositions and contributions in different areas.In devolved regions,OFP-NMHCs are the highest in winter while OFP-OVOCs are the highest in summer.Based on positive matrix factorization(PMF)analysis,vehicle exhaust,industrial emissions,and solvent usage in China are the main sources for NMHCs.However,the emission trend analysis showed that solvent usage and industrial emissions will exceed vehicle exhaust and become the two major sources of NMVOCs in near future.Based on the meta-analysis conducted in this work,we believe that the spatio-temporal variations and oxidation mechanisms of atmospheric OVOCs,as well as generating a higher spatial resolution of emission inventories of NMVOCs represent an area for future studies on NMVOCs in China. | Fanglin WANG Wei DU Shaojun LV Zhijian DING Gehui WANG | 2021 | Advances in Atmospheric Sciences2021，38，7： | 4 |
| 16 | The LRXs-RALFs-FER module controls plant growth and salt stress responses by modulating multiple plant hormones显示文摘Salt stress is a major environmental factor limiting plant growth and productivity.We recently discovered an important new salt tolerance pathway,where the cell wall leucine-rich repeat extensins LRX3/4/5,the RAPID ALKALINIZATION FACTOR(RALF)peptides RALF22/23 and receptor-like kinase FERONIA(FER)function as a module to simultaneously regulate plant growth and salt stress tolerance.However,the intracellular signaling pathways that are regulated by the extracellular LRX3/4/5-RALF22/23-FER module to coordinate growth,cell wall integrity and salt stress responses are still unknown.Here,we report that the LRX3/4/5-RALF22/23-FER module negatively regulates the levels of jasmonic acid(JA),salicylic acid(SA)and abscisic acid(ABA).Blocking JA pathway rescues the dwarf phenotype of the lrx345 and fer-4mutants,while disruption of ABA biosynthesis suppresses the salt-hypersensitivity of these mutants.Many salt stress-responsive genes display abnormal expression patterns in the lrx345 and fer-4 mutants,as well as in the wild type plants treated with epigallocatechin gallate(EGCG),an inhibitor of pectin methylesterases,suggesting cell wall integrity as a critical factor that determines the expression pattern of stress-responsive genes.Production of reactive oxygen species(ROS)is constitutively increased in the lrx345 and fer-4mutants,and inhibition of ROS accumulation suppresses the salt-hypersensitivity of these mutants.Together,our work provides strong evidence that the LRX3/4/5-RALF22/23-FER module controls plant growth and salt stress responses by regulating hormonal homeostasis and ROS accumulation. | Chunzhao Zhao Wei Jiang Omar Zayed Xin Liu Kai Tang Wenfeng Nie Yali Li Shaojun Xie Yuan Li Tiandan Long Linlin Liu Yingfang Zhu Yang Zhao Jian-Kang Zhu | 2021 | National Science Review2021，8，1： | 3 |
| 17 | Row-based configuration mechanism for a 2-D processing element array in coarse-grained reconfigurable architecture显示文摘Using the coarser operand grain and simplified interconnection patterns, CGRA(coarse grained reconfigurable architectures) has been proven to be energy efficient in several specific domains. As we know, the speed at which the contexts are applied to a PEA(processing element array) directly determines the performance of CGRA. In this paper, the design space in CGRA is further developed from the configuration granularity perspective by one middle-grained configuration granularity—the row-based configuration mechanism(RCM).The most prominent feature of the RCM is that a large DFG(data flow graph) can be mapped onto a small array in once reconfiguration, which is carried out on a row-by-row basis. Compared with an ordinary DFGpartitioning solution, the reconfiguration time and the data transfer time are well reduced. Furthermore, the proposed RCM offers much more efficient storage for the contexts. Compared with the DFG partitioning solution,the performance is boosted from 2.6% to 57.8%, while the area penalty is only 4.79% and the power penalty is only 7.22%. The RCM has been used in one reconfigurable processor called REMUS HPA(reconfigurable multi-media system, high performance version advanced). REMUS HPA has been implemented on a 50.5 mm2 silicon with TSMC 65 nm technology. Simulation shows that 1920×1088@37 fps can be achieved for H.264high-profile decoding when exploiting a 200 MHz working frequency. Compared with the high performance version of XPP(one commercial reconfigurable processor), the performance is 247% boosted. | LIU LeiBo WANG YanSheng YIN ShouYi ZHU Min WANG Xing WEI ShaoJun | 2014 | Science China(Information Sciences)2014，57，10： | 3 |
| 18 | A comparative study of distant hybridization in plants and animals显示文摘Distant hybridization refers to crosses between two different species, genera, or higher-ranking taxa, which can break species limits, increase genetic variation, and combine the biological characteristics of existing species. It is an important way of creating genetic variation, fertile strains, and excellent characteristics in new strains and populations. Combining analyses and summaries from many inter-related documents in plants and animals, both domestic and international, including examples and long-standing research on distant hybridization in fish from our laboratory, we summarize and compare the similarities and differences in plant and animal distant hybridization. In addition, we analyze and review the biological characteristics of their different ploidy progenies and the possible causes of disparity in survival rates. Mechanisms of sterility in animal and plant distant hybrids are also discussed, and research methods for the study of biological characteristics of hybrids, including morphology, cytology,and molecular cytogenetics are presented. This paper aims to provide comprehensive research materials and to systematically compare the general and specific characteristics of plant and animal hybrids with regards to reproduction, genetics, growth traits,and other biological characteristics. It is hoped that this paper will have great theoretical and practical significance for the study of genetic breeding and biological evolution of plant and animal distant hybridization. | Jie Chen Mi Luo Shengnan Li Min Yao Xiaolan Ye Wei Duan Chun Zhang Qinbo Qin Jun Xiao Shaojun Liu | 2018 | Science China(Life Sciences)2018，61，3： | 3 |
| 19 | Natural variations in grain length 10(GL10)regulate rice grain size显示文摘Grain size is an important determinant of grain weight and yield in rice.Although several genes related to grain size have been identified,natural variations in these genes that affect grain size are poorly characterized.Here,we describe the grain length QTL GL10,encoding MADS56,which positively regulates grain length and grain weight.A natural allelic variation of NIL-gl10,containing an~1.0-kb deletion in the first exon that abolishes its transcription,results in shorter grain length,lower grain weight and delayed flowering in gl10 plants.The knockout of GL10 in the HJX74 background leads to grain phenotypes similar to that of NIL-gl10,while overexpression of GL10 results in increased grain length and weight and earlier heading date.GL10 regulates grain length by promoting greater longitudinal cell growth in the grain glume.Additionally,GL10 participates in the regulation of gibberellic acid(GA)signaling pathway genes in young panicle tissues.Analysis of GL10 haplotypes shows obvious divergence between the japonica and indica lineages.Our findings reveal an allelic variation of GL10 that may explain differences in grain length among modern cultivars and could be used to breed rice varieties with optimized grain shape. | Penglin Zhan Shuaipeng Ma Zhili Xiao Fangping Li Xin Wei Shaojun Lin Xiaoling Wang Zhe Ji Yu Fu Jiahao Pan Mi Zhou Yue Liu Zengyuan Chang Lu Li Suhong Bu Zupei Liu Haitao Zhu Guifu Liu Guiquan Zhang Shaokui Wang | 2022 | Journal of Genetics and Genomics2022，49，5： | 3 |
| 20 | Single-atom catalysts supported on ordered porous materials:Synthetic strategies and applications显示文摘Single-atom catalysts(SACs)are attracting extensive attention due to their incredibly catalytic activity and selectivity,high utilization of metal atoms,and obvious cost reduction.The unique ordered porous materials(OPMs)are promising carriers for stabilizing single atoms due to their large surface areas and uniformly tunable pore sizes.Meantime,the geometric and electronic structures of single-atom metals can be tuned by the interaction between the single-atoms(SAs)and OPMs to enhance the catalytic activity of SACs.The SACs based on OPMs,such as zeolites,metal-organic frameworks,and ordered mesoporous materials,have been developing fast recently.Herein,we review recent advancements on structural feature,synthetic strategy,characterization technique,and catalytic applications of OPMs-based SACs.The opportunities and challenges about SAs/OPMs are also provided to develop the novel catalysts with superior catalytic performances in the future. | Kaiwen Xue Yan Mo Baojun Long Wen Wei Changsheng Shan Shaojun Guo Li Niu | 2022 | InfoMat2022，4，6： | 3 |
