| 1 | Wx^lv、the Ancestral Allele of Rice Waxy Gene显示文摘In rice grains,the Waxy (Wx) gene is responsible for the synthesis of amylose,the most important determinant for eating and cooking quality.The effects of several Wx alleles on amylose content and the taste of cooked rice have been elucidated.However,the relationship between artificial selection and the evolution of various Wx alleles as well as their distribution remain unclear.Here we report the identification of an ancestral allele,Wx^lv,which dramatically affects the mouthfeel of rice grains by modulating the size of amylose molecules.We demonstrated that WF originated directly from wild rice,and the three major Wx alleles in cultivated rice (Wx^b,Wx^a,and Wx^in) differentiated after the substitution of one base pair at the functional sites.These data indicate that the Wx^lv allele played an important role in artificial selection and domestication.The findings also shed light on the evolution of various Wx alleles,which have greatly contributed to improving the eating and cooking quality of rice. | Changquan Zhang Jihui Zhu Shengjie Chen Xiaolei Fan Qianfeng Li Yan Lu Min Wang Hengxiu Yu Chuandeng Yi Shuzhu Tang Minghong Gu Qiaoquan Liu | 2019 | Molecular Plant2019，12，8： | 22 |
| 2 | A rare Waxy allele coordinately improves rice eating and cooking quality and grain transparency显示文摘In rice(Oryza sativa), amylose content(AC) is the major factor that determines eating and cooking quality(ECQ). The diversity in AC is largely attributed to natural allelic variation at the Waxy(Wx)locus. Here we identified a rare Wx allele, Wx^(mw) ,which combines a favorable AC, improved ECQ and grain transparency. Based on a phylogenetic analysis of Wx genomic sequences from 370 rice accessions, we speculated that Wx^(mw) may have derived from recombination between two important natural Wx alleles, Wx^(in) and Wx^(b). We validated the effects of Wx^(mw) on rice grain quality using both transgenic lines and near-isogenic lines(NILs). When introgressed into the japonica Nipponbare(NIP) background, Wx^(mw) resulted in a moderate AC that was intermediate between that of NILs carrying the Wx^(b)allele and NILs with the Wx^(mp) allele. Notably, mature grains of NILs fixed for Wx^(mw) had an improved transparent endosperm relative to soft rice. Further, we introduced Wx^(mw) into a high-yielding japonica cultivar via molecular marker-assisted selection: the introgressed lines exhibited clear improvements in ECQ and endosperm transparency. Our results suggest that Wx^(mw) is a promising allele to improve grain quality, especially ECQ and grain transparency of high-yielding japonica cultivars, in rice breeding programs. | Changquan Zhang Yong Yang Shengjie Chen Xueju Liu Jihui Zhu Lihui Zhou Yan Lu Qianfeng Li Xiaolei Fan Shuzhu Tang Minghong Gu Qiaoquan Liu | 2021 | Journal of Integrative Plant Biology2021，63，5： | 18 |
| 3 | Development of gene-tagged molecular markers for starch synthesis-related genes in rice显示文摘Improving grain quality is an important goal in breeding new elite rice varieties,requiring effective tools for the identification of target genotypes.Molecular marker-aided selection(MAS),combined with conventional breeding approaches,enables us to pre-cisely identify the individual genotypes that are associated with different grain quality features,which can dramatically improve the breeding efficiency.However,to date,the number of molecular markers used in MAS for grain quality improvement is still somewhat limited.In this study,based on our previous study that rice grain quality is strongly associated with starch synthesis in the endosperm,we developed 51 gene-tagged molecular markers according to sequence variations in 18 starch synthesis-related genes from 16 typical rice cultivars.These markers can discriminate the different alleles among rice germplasms.These novel markers will provide effective tools in improving grain quality via the breeding new elite rice varieties. | TIAN ZhiXi YAN ChangJie QIAN Qian YAN Song XIE HuiLan WANG Fang XU JieFen LIU GuiFu WANG YongHong LIU QiaoQuan TANG ShuZhu LI JiaYang GU MingHong | 2010 | Chinese Science Bulletin2010，55，33： | 12 |
| 4 | Development and characterization of interspecific hybrids between Oryza sativa and O. latifolia by in situ hybridization显示文摘Oryza sativa and O. latifolia belong to the AA and CCDD genomes of Oryza, respectively. In this study, interspecific hybrids of these species were obtained using the embryo rescue technique. Hybrid panicle traits, such as long awns, small grain, exoteric large purple stigma, grain shattering and dispersed panicles, resemble that of the paternal parent, O. latifolia, whereas there is obvious heterosis in such respects as plant height, tillering ability and vegetative vigor. Chromosome pairing and the genomic components of the hybrid were subsequently investigated using genomic in situ hybridization (GISH) and fluorescent in situ hybridization (FISH) analysis. Based on the mitotic metaphase chromosome numbers of the root tips investigated, the hybrid is a triploid with 36 chromosomes. The genomic constitution of the hybrid is ACD. In the meiotic metaphase I of the hybrid pollen mother cell, poor chro- mosome pairing was identified and most of the chromosomes were univalent, which resulted in com- plete male sterility in the hybrid. | YI ChuanDeng TANG ShuZhu ZHOU Yong LIANG GuoHua GONG ZhiYun GU MingHong | 2008 | Chinese Science Bulletin2008，53，19： | 4 |
| 5 | Design and Implementation of Hardware Architecture in Ionospheric Oblique Backscattering Sounding System显示文摘The ionospheric oblique backscattering sounding sys-tem can not only be used to detect the state of the ionosphere and the condition of high frequency channel in real time, but also be used for over-the-horizon sounding. Therefore, it has a very high military and civil value. For the characteristics of ionospheric oblique backscattering sounding, such as long sounding distance, wake echo, strong background noise, slow moving target, etc., a hardware platform of ionospheric oblique backscattering sounding system is designed. This platform adopts the technology of soft-ware radio and is designed as a new kind of general purpose, modularized, software-based ionosonde that is based on the VXI (Versa module eurocard eXtensions for Instrumentation) bus. This hardware platform has been successfully used in actual iono-spheric oblique backscattering sounding, and the experimental results demonstrate that this system can satisfy the requirements. | SHI Shuzhu ZHAO Zhengyu YANG Guobin ZHANG Yuannong LIU Ruiyuan | 2009 | Wuhan University Journal of Natural Sciences2009，14，1： | 3 |

| 8 | Doppler estimating and compensating method based on phase显示文摘According to the Doppler sensitive of the phase coded pulse compression signal,a Doppler estimating and compensating method based on phase is put forward to restrain the Doppler sidelobes,raise the signal-to-noise ratio and improve measuring resolution.The compensation method is used to decompose the echo to amplitude and phase,and then compose the new compensated echo by the amplitude and the nonlinear component of the phase. Furthermore the linear component of the phase can be used to estimate the Doppler frequency shift.The computer simulation and the real data processing show that the method has accurately estimated the Doppler frequency shift, successfully restrained the energy leakage on spectrum,greatly increased the echo signal-to-noise ratio and improved the detection performance of the radio system in both time domain and frequency domain. | Chen Gang Zhao Zhengyu Nie Xuedong Shi Shuzhu Yang Guobin Su Fanfan | 2009 | Journal of Systems Engineering and Electronics2009，20，4： | 2 |
| 9 | Molecular marker for screening rice cultivars with intermediate amylose content in indica显示文摘The waxy(Wx)gene of rice encodes the granule-bound starch synthase(GBSS),which was required in the synthesis of amylose in endosperm.Theamylose content(AC)of rice endosperm played an important role in grain yield,palatability,and processing quality.Our previous researehes showed that en-dosperm AC and GBSS contents were correlated with the ability of excising intron1 from the leader sequence of the Wx transcript.Cultivars with high | CAI Xiuling~(1)) LIU Qiaoquan~(2)) TANG Shuzhu~(2)) GU Minghong~(2)) WANG Zongyang~(1)) 1)Shanghai Inst of Plant Physiology,the Chinese Academy of Sciences,Shanghai 200032 2)College of Bioscienee and Biotechnology,Yangzhou Univ,Yangzhou 225009,China | 2002 | Chinese Rice Research Newsletter2002，10，3： | 1 |

| 15 | Mechanical alloying characteristic and thermal stability of Al_(78)Fe_(20)Zr_2 amorphous powders显示文摘The powders of pure Al, Fe, and Zr for preparing Al78Fe20Zr2 were subject to a high-energy planetary ball milling.The microstructure evolution of the mixtures at the different intervals of milling was characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM) and differential scanning calorimetry(DSC).It was found that a nearly complete amorphization could be achieved in the mixtures after ball milling for 23 h.Further ball milling led to the crystallization of the amorphous powders.A long time ball milling, e.g., 160 h, led to a complete crystallization of the amorphous powders and the formation of Al3Zr and Al13Fe4.The crystallization products caused by ball milling are almost the same as that produced by isothermal annealing of the amorphous powders in vacuum at 800 K for 1 h. | ZHOU Shuzhu WANG Wenwu | 2010 | Rare Metals2010，29，2： | 1 |

| 20 | Identification and fine mapping of a fertility restorer gene for wild abortive cytoplasmic male sterility in the elite indica rice non-restorer line 9311显示文摘The wild abortive(WA)-type cytoplasmic male sterility(CMS)derived from the wild rice species Oryza rufipogon Griff.is used widely in three-line indica hybrids.The identification and mapping of restorer of fertility(Rf)genes aided in the development of WA-type hybrids.Here we report that testcross F1 plants from the WA-type CMS line and 9311 exhibited stainable pollen grains with no seed set,indicating that 9311 carries minor-effect Rfs for WA-type CMS.We developed an advanced backcross population consisting of plants harboring small regions of donor chromosomal segments from 9311 in the WATianfeng A genetic background with moderate seed setting rates.Genetic analysis showed that the pollen fertility levels of the backcross individuals are governed by a single gene from 9311 that we named Rf19(t).By use of the RICE 40 K gene chip,three introduced segments were identified in the fertile lines,and a candidate region spanning 4.37–8.29 Mb on chromosome 1 was identified for Rf19(t).Finally,Rf19(t)was fine-mapped to a region of 90 kb between the DNA marker loci STS1-163 and STS1-183,in which eight ORFs were predicted.Also,using relative expression analyses,comparative sequence analyses and functional domain analyses,we identified LOC_Os01g10530 as the most likely candidate gene for Rf19(t).Furthermore,Rf19(t)was found to function in fertility restoration,most probably by regulating the degradation of m RNA transcribed from the mitochondrial gene WA352.These results increase our knowledge of fertility restoration in WA-type CMS lines and will facilitate the development of high-quality pairs of WAtype CMS and maintainer lines. | Zuopeng Xu Yuanyue Du Xixu Li Ruixuan Wang Zhi'ai Chen Xiangqiang Zhao Qiaoquan Liu Shuzhu Tang Honggen Zhang | 2023 | The Crop Journal2023，11，3： | 0 |
