| 1 | Construction of a cucumber genetic linkage map with SRAP markers and location of the genes for lateral branch traits显示文摘Using SRAP (sequence-related amplified polymorphism) markers a genetic linkage map of cucumber was constructed with a population consisting of 138 F2 individuals derived from a cross of the two cucumber lines, S06 and S52. In the survey of parental polymorphisms with 182 primer combinations, 64 polymorphism-revealing primer pairs were screened out, which generated totally 108 polymorphic bands with an average of 1.7 bands per primer pair and at most 6 bands from one primer pair. The constructed molecular linkage map included 92 loci, distributed in seven linkage groups and spanning 1164.2 cM in length with an average genetic distance of 12.6 cM between two neighboring loci. Based on this linkage map, the quantitative trait loci (QTL) for the lateral branch number (lbn) and the lateral branch average length (lbl) in cucumber were identified by QTLMapper1.6. A major QTL lbn1 located between ME11SA4B and ME5EM5 in LG2 could explain 10.63% of the total variation with its positively effecting allele from S06. A major QTL lbl1 located between DC1OD3 and DC1EM14 in LG2 could account for 10.38% of the total variation with its positively effecting allele from S06. | WANG Gang PAN Junsong LI Xiaozun HE Huanle WU Aizhong CAI Run | 2005 | Science China(Life Sciences)2005，48，3： | 24 |
| 2 | Future extreme climate changes linked to global warming intensity显示文摘Based on the Coupled Model Intercomparison Project Phase 5(CMIP5) daily dataset, we investigate changes of the terrestrial extreme climates given that the global mean temperature increases persistently under the Representative Concentration Pathways 8.5(RCP8.5) scenario. Compared to preindustrial conditions, more statistically significant extreme temperatures, precipitations, and dry spells are expected in the 21 st century. Cold extremes decrease and warm extremes increase in a warmer world, and cold extremes tend to be more sensitive to global warming than the warm ones. When the global mean temperature increases, cold nights, cold days, and warm nights all display nonlinear relationships with it,such as the weakening of the link projected after 3 °C global warming, while the other indices generally exhibit differently, with linear relationships. Additionally, the relative changes in the indices related to extreme precipitation show significantly consistent linear changes with the global warming magnitude.Compared with the precipitation extremes, changes in temperature extremes are more strongly related to the global mean temperature changes. For the projection of the extreme precipitation changes, models show higher uncertainty than that in extreme temperature changes, and the uncertainty for the precipitation extremes becomes more remarkable when the global warming exceeds 5 °C. | Xiaoxin Wang Dabang Jiang Xianmei Lang | 2017 | Science Bulletin2017，62，24： | 20 |
| 3 | A high-quality chromosome-level genome assembly reveals genetics for important traits in eggplant显示文摘Eggplant(Solanum melongena L.)is an economically important vegetable crop in the Solanaceae family,with extensive diversity among landraces and close relatives.Here,we report a high-quality reference genome for the eggplant inbred line HQ-1315(S.melongena-HQ)using a combination of Illumina,Nanopore and 10X genomics sequencing technologies and Hi-C technology for genome assembly.The assembled genome has a total size of~1.17 Gb and 12 chromosomes,with a contig N50 of 5.26 Mb,consisting of 36,582 protein-coding genes.Repetitive sequences comprise 70.09%(811.14 Mb)of the eggplant genome,most of which are long terminal repeat(LTR)retrotransposons(65.80%),followed by long interspersed nuclear elements(LINEs,1.54%)and DNA transposons(0.85%).The S.melongena-HQ eggplant genome carries a total of 563 accession-specific gene families containing 1009 genes.In total,73 expanded gene families(892 genes)and 34 contraction gene families(114 genes)were functionally annotated.Comparative analysis of different eggplant genomes identified three types of variations,including singlenucleotide polymorphisms(SNPs),insertions/deletions(indels)and structural variants(SVs).Asymmetric SV accumulation was found in potential regulatory regions of protein-coding genes among the different eggplant genomes.Furthermore,we performed QTL-seq for eggplant fruit length using the S.melongena-HQ reference genome and detected a QTL interval of 71.29–78.26 Mb on chromosome E03.The gene Smechr0301963,which belongs to the SUN gene family,is predicted to be a key candidate gene for eggplant fruit length regulation.Moreover,we anchored a total of 210 linkage markers associated with 71 traits to the eggplant chromosomes and finally obtained 26 QTL hotspots.The eggplant HQ-1315 genome assembly can be accessed at http://eggplant-hq.cn.In conclusion,the eggplant genome presented herein provides a global view of genomic divergence at the whole-genome level and powerful tools for the identification of candidate genes for important traits in eggplant. | Qingzhen Wei Jinglei Wang Wuhong Wang Tianhua Hu Haijiao Hu Chonglai Bao | 2020 | Horticulture Research2020，7，1： | 12 |
| 4 | Quasispecies structure,cornerstone of hepatitis B virus infection: Mass sequencing approach显示文摘Hepatitis B virus(HBV)is a DNA virus with complex replication,and high replication and mutation rates,leading to a heterogeneous viral population.The population is comprised of genomes that are closely related,but not identical;hence,HBV is considered a viral quasispecies.Quasispecies variability may be somewhat limited by the high degree of overlapping between the HBV coding regions,which is especially important in the P and S gene overlapping regions,but is less significant in the X and preCore/Core genes.Despite this restriction,several clinically and pathologically relevant variants have been characterized along the viral genome.Next-generation sequencing(NGS)approaches enable high-throughput analysis of thousands of clonally amplified regions and are powerful tools for characterizing genetic diversity in viral strains.In the present review,we update the information regarding HBV variability and present a summary of the various NGS approaches available for research in this virus.In addition,we provide an analysis of the clinical implications of HBV variants and their study by NGS. | Francisco Rodriguez-Frias Maria Buti David Tabernero Maria Homs | 2013 | World Journal of Gastroenterology2013，19，41： | 11 |
| 5 | Construction of an anchoring SSR marker genetic linkage map and detection of a sex-linked region in two dioecious populations of red bayberry显示文摘Red bayberry(Morella rubra)is an evergreen fruit tree found in southern China whose whole-genome sequence has recently been published.We updated the linkage map of the species by adding 118 SSR markers and the femalespecific marker MrFT2_BD-SEX.The integrated map included eight linkage groups and spanned 491 cM.Eleven sexassociated markers were identified,six of which were located in linkage group 8,in agreement with the previously reported location of the sex-determining region.The MrFT2_BD-SEX marker was genotyped in 203 cultivated accessions.Among the females of the accessions,we found two female-specific alleles,designated W-b(151 bp)and W-d(129 bp).We previously found that‘Dongkui’,a female cultivar,could produce viable pollen(we refer to such plants‘Dongkui-male’)and serve as the paternal parent in crosses.The genotypes of the MrFT2_BD-SEX marker were W-b/Z in‘Biqi’and W-d/Z in‘Dongkui-male’.The progeny of a cross between these parents produced a 3:1 female(W-)to male(ZZ)ratio and the expected 1:1:1:1 ratio of W-b/W-d:W-b/Z:W-d/Z:Z/Z.In addition,the flowering and fruiting phenotypes of all the F1 progeny fit their genotypes.Our results confirm the existence of ZW sex determination and show that the female phenotype is controlled by a single dominant locus(W)in a small genomic region(59 kb and less than 3.3 cM).Furthermore,we have produced a homozygous“super female”(WW)that should produce all-female offspring in the F2 generation,providing a foundation for commercial use and presenting great potential for use in modern breeding programs. | Yan Wang Hui-Min Jia Yu-Tong Shen Hai-Bo Zhao Qin-Song Yang Chang-Qing Zhu De-Li Sun Guo-Yun Wang Chao-Chao Zhou Yun Jiao Chun-Yan Chai Li-Ju Yan Xiong-Wei Li Hui-Juan Jia Zhong-Shan Gao | 2020 | Horticulture Research2020，7，1： | 10 |
| 6 | Elucidation of the ‘Honeycrisp’ pedigree through haplotype analysis with a multi-family integrated SNP linkage map and a large apple (Malus×domestica) pedigree-connected SNP data set显示文摘The apple(Malus×domestica)cultivar Honeycrisp has become important economically and as a breeding parent.An earlier study with SSR markers indicated the original recorded pedigree of‘Honeycrisp’was incorrect and‘Keepsake’was identified as one putative parent,the other being unknown.The objective of this study was to verify‘Keepsake’as a parent and identify and genetically describe the unknown parent and its grandparents.A multi-family based dense and high-quality integrated SNP map was created using the apple 8 K Illumina Infinium SNP array.This map was used alongside a large pedigree-connected data set from the RosBREED project to build extended SNP haplotypes and to identify pedigree relationships.‘Keepsake’was verified as one parent of‘Honeycrisp’and‘Duchess of Oldenburg’and‘Golden Delicious’were identified as grandparents through the unknown parent.Following this finding,siblings of‘Honeycrisp’were identified using the SNP data.Breeding records from several of these siblings suggested that the previously unreported parent is a University of Minnesota selection,MN1627.This selection is no longer available,but now is genetically described through imputed SNP haplotypes.We also present the mosaic grandparental composition of‘Honeycrisp’for each of its 17 chromosome pairs.This new pedigree and genetic information will be useful in future pedigree-based genetic studies to connect‘Honeycrisp’with other cultivars used widely in apple breeding programs.The created SNP linkage map will benefit future research using the data from the Illumina apple 8 and 20 K and Affymetrix 480 K SNP arrays. | Nicholas P Howard Eric van de Weg David S Bedford Cameron P Peace Stijn Vanderzande Matthew D Clark Soon Li Teh Lichun Cai James J Luby | 2017 | Horticulture Research2017，4，1： | 9 |
| 7 | Modeling of bearingless permanent magnet synchronous motor based on mechanical to electrical coordinates transformation显示文摘A bearingless permanent magnet synchronous motor(BPMSM)has two sets of stator windings,torque windings and suspension force windings.By analyzing the flux linkage intersection between the two sets of windings,a method of transforming mechanical coordinates to electrical coordinates is put forward.According to this method,flux linkage equations and voltage equations of the two stator windings are derived.The electromagnetic torque equation of the BPMSM is derived based on the analysis of the role of Lorentz force in the BPMSM.After analyzing the mathematical formula of various sort radial forces in the BPMSM,a complete function of radial suspension forces for the BPMSM is obtained.Finally,an experimental system control diagram and some test results are discussed.This mathematical model provides a theoretical foundation for BPMSM simulation study,experiment waveform analysis and structure design. | ZHU HuangQiu CHENG QiuLiang WANG ChengBo | 2009 | Science China(Technological Sciences)2009，52，12： | 8 |
| 8 | Wheat powdery mildew resistance gene Pm64 derived from wild emmer (Triticum turgidum var.dicoccoides) is tightly linked in repulsion with stripe rust resistance gene Yr5显示文摘Stripe rust and powdery mildew are both devastating diseases for durum and common wheat.Pyramiding of genes conferring resistance to one or more diseases in a single cultivar is an important breeding approach to provide broader spectra of resistances in wheat improvement. A new powdery mildew resistance gene originating from wild emmer(Triticum turgidum var.dicoccoides) backcrossed into common wheat(T. aestivum) line WE35 was identified. It conferred an intermediate level of resistance to Blumeria graminis f. sp. tritici isolate E09 at the seedling stage and a high level of resistance at the adult plant stage. Genetic analysis showed that the powdery mildew resistance in WE35 was controlled by a dominant gene designated Pm64. Bulked segregant analysis(BSA) and molecular mapping indicated that Pm64 was located in chromosome bin 2 BL4-0.50–0.89. Polymorphic markers were developed from the corresponding genomic regions of Chinese Spring wheat and wild emmer accession Zavitan to delimit Pm64 to a 0.55 cM genetic interval between markers WGGBH1364 and WGGBH612, corresponding to a 15 Mb genomic region on Chinese Spring and Zavitan 2 BL, respectively. The genetic linkage map of Pm64 is critical for fine mapping and cloning. Pm64 was completely linked in repulsion with stripe rust resistance gene Yr5. Analysis of a larger segregating population might identify a recombinant line with both genes as a valuable resource in breeding for resistance to powdery mildew and stripe rust. | Deyun Zhang Keyu Zhu Lingli Dong Yong Liang Genqiao Li Tilin Fang Guanghao Guo Qiuhong Wu Jingzhong Xie Yongxing Chen Ping Lu Miaomiao Li Huaizhi Zhang Zhenzhong Wang Yan Zhang Qixin Sun Zhiyong Liu | 2019 | The Crop Journal2019，7，6： | 8 |
| 9 | Linkage of microbiota and osteoporosis:A mini literature review显示文摘The gut microbiota(GM) has become a recent topic of interest in the role of many disease states. Assessing patients with osteoporosis(OP), there is a strong correlation between gut microbe dysregulation and decreased bone density. Gut dysbiosis may lead to inflammation, dysregulation of nutrient and calcium transport across the intestine into circulation and systemic inflammation.Investigation of microbial profile relative to normal gut microbiomes, assessment of inflammatory markers such as interleukin-1(IL-1), IL-6, and tumor necrosis factor-alpha. Therapies to normalize GM in patients with OP or prevent occurrence of OP to be investigated include: High fiber prebiotic diets to promote growth of normal gut bacteria and short chain fatty acid production, Probiotics to encourage growth of normal gut microbes, and antibiotic treatment followed by fecal matter transplant. | David Yatsonsky Ⅱ Karen Pan Vithal B Shendge Jiayong Liu Nabil A Ebraheim | 2019 | World Journal of Orthopedics2019，10，3： | 7 |
| 10 | Transformative hyaluronic acid-based active targeting supramolecular nanoplatform improves long circulation and enhances cellular uptake in cancer therapy显示文摘Hyaluronic acid(HA) is a natural ligand of tumor-targeted drug delivery systems(DDS) due to the relevant CD44 receptor overexpressed on tumor cell membranes. However, other HA receptors(HARE and LYVE-1) are also overexpressing in the reticuloendothelial system(RES). Therefore,polyethylene glycol(PEG) modification of HA-based DDS is necessary to reduce RES capture.Unfortunately, pegylation remarkably inhibits tumor cellular uptake and endosomal escapement,significantly compromising the in vivo antitumor efficacy. Herein, we developed a Dox-loaded HA-based transformable supramolecular nanoplatform(Dox/HCVBP) to overcome this dilemma. Dox/HCVBP contains a tumor extracellular acidity-sensitive detachable PEG shell achieved by a benzoic imine linkage.The in vitro and in vivo investigations further demonstrated that Dox/HCVBP could be in a 'stealth' state at blood stream for a long circulation time due to the buried HA ligands and the minimized nonspecific interaction by PEG shell. However, it could transform into a 'recognition' state under the tumor acidic microenvironment for efficient tumor cellular uptake due to the direct exposure of active targeting ligand HA following PEG shell detachment. Such a transformative concept provides a promising strategy to resolve the dilemma of natural ligand-based DDS with conflicting two processes of tumor cellular uptake and in vivo nonspecific biodistribution. | Lu Zhong Lu Xu Yanying Liu Qingsong Li Dongyang Zhao Zhenbao Li Huicong Zhang Haotian Zhang Qiming Kan Yongjun Wang Jin Sun Zhonggui He | 2019 | Acta Pharmaceutica Sinica B2019，9，2： | 7 |
| 11 | Identification of salt-tolerance QTL in rice(Oryza sativa L.)显示文摘Quantitative trait loci (QTLs) controlling salt-tolerance at the seedling stage in rice (Oryza sativa L.) were identified by interval mapping (SIM) and composite interval mapping (CIM) using a doubled haploid population ZJDH and its high resolution genetic linkage map. The population was derived from an inter-subspecific cross between an indica variety Zhaiyeqing8 (ZYQ8) and a japonica variety Jingxi17 (JX17). Analysis of survival days of seedlings treated with 0.7% NaCl revealed that a major salt-tolerance quantitative trait locus (QTL), Std, was present between markers RG612 and C131 on chromosome 1 when using both MAPMAKER/QTL 1.1 and PLABQTL 1.0 (SIM).Its allele which contributes to salt-tolerance was from ZYQ8. In addition, seven more QTLs which give additive effect on salt-tolerance are identified when using PLABQTL(CIM), and most of them were from JX17. | Jiming Gong Ping He Qian Qian Lishuang Shen Lihuang Zhu Shouyi Chen | 1999 | Chinese Science Bulletin1999，44，1： | 7 |
| 12 | Structure optimal design research on backfill hydraulic support显示文摘Backfill hydraulic support is the key equipment in achieving coal mining and solid backfilling simultaneously in solid backfill mining technology.Based on the summary and analysis of main types,basic structural properties and filed application of backfill hydraulic support,this work has firstly proposed the basic principle of backfill hydraulic support optimization design and provided the method of optimal design of key structural components,like four-bar linkage,rear canopy and tamping structure;the method is further elaborated as changing hinging position of upper bar to optimize four-bar linkage,by lengthening or shortening the rear canopy to optimize length ratio of canopy;and by changing length and hinging position of tamping structure as well as suspension height of backfill scrape conveyor to realize optimization of tamping structure.On this basis,the process of optimal design of backfill hydraulic support is built.The optimal design case of ZC5200/14.5/30 six columns-four bar linkage used in 7203 W workface of Zhaizhen Coal Mine shows that the backfill properties like horizontal roof gap,vertical horizontal gap,tamping angle and tamping head gap are improved obviously through optimizing four-bar linkage,canopy length and tamping structure according to the optimal design method proposed in this work. | 张强 张吉雄 齐文跃 周楠 邰阳 | 2017 | Journal of Central South University2017，24，7： | 7 |
| 13 | Zea mays(L.) P1 locus for cob glume color identified as a post-domestication selection target with an effect on temperate maize genomes显示文摘Artificial selection during domestication and post-domestication improvement results in loss of genetic diversity near target loci. However, the genetic locus associated with cob glume color and the nature of the genomic pattern surrounding it was elusive and the selection effect in that region was not clear. An association mapping panel consisting of 283 diverse modern temperate maize elite lines was genotyped by a chip containing over 55,000 evenly distributed SNPs. Ten-fold resequencing at the target region on 40 of the panel lines and 47 tropical lines was also undertaken. A genome-wide association study(GWAS) for cob glume color confirmed the P1 locus, which is located on the short arm of chromosome 1, with a-log10 P value for surrounding SNPs higher than the Bonferroni threshold(α/n, α < 0.001) when a mixed linear model(MLM) was implemented. A total of 26 markers were identified in a 0.78 Mb region surrounding the P1 locus, including 0.73 Mb and 0.05 Mb upstream and downstream of the P1 gene, respectively. A clear linkage disequilibrium(LD) block was found and LD decayed very rapidly with increasing physical distance surrounding the P1 locus. The estimates of π and Tajima's D were significantly(P < 0.001) lower at both ends compared to the locus. Upon comparison of temperate and tropical lines at much finer resolution by resequencing(180-fold finer than chip SNPs), a more structured LD block pattern was found among the 40 resequenced temperate lines. All evidence indicates that the P1 locus in temperate maize has not undergone neutral evolution but has been subjected to artificial selection during post-domestication selection or improvement. The information and analytical results generated in this study provide insights as to how breeding efforts have affected genome evolution in crop plants. | Chuanxiao Xie Jianfeng Weng Wenguo Liu Cheng Zou Zhuanfang Hao Wenxue Li Minshun Li Xiaosen Guo Gengyun Zhang Yunbi Xu Xinhai Li Shihuang Zhang | 2013 | The Crop Journal2013，1，1： | 6 |
| 14 | High-density SNP-based genetic maps for the parents of an outcrossed and a selfed tetraploid garden rose cross, inferred from admixed progeny using the 68k rose SNP array显示文摘Dense genetic maps create a base for QTL analysis of important traits and future implementation of marker-assisted breeding.In tetraploid rose,the existing linkage maps include<300 markers to cover 28 linkage groups(4 homologous sets of 7 chromosomes).Here we used the 68k WagRhSNP Axiom single-nucleotide polymorphism(SNP)array for rose,in combination with SNP dosage calling at the tetraploid level,to genotype offspring from the garden rose cultivar‘Red New Dawn’.The offspring proved to be not from a single bi-parental cross.In rose breeding,crosses with unintended parents occur regularly.We developed a strategy to separate progeny into putative populations,even while one of the parents was unknown,using principle component analysis on pairwise genetic distances based on sets of selected SNP markers that were homozygous,and therefore uninformative for one parent.One of the inferred populations was consistent with self-fertilization of‘Red New Dawn’.Subsequently,linkage maps were generated for a bi-parental and a self-pollinated population with‘Red New Dawn’as the common maternal parent.The densest map,for the selfed parent,had 1929 SNP markers on 25 linkage groups,covering 1765.5 cM at an average marker distance of 0.9 cM.Synteny with the strawberry(Fragaria vesca)genome was extensive.Rose ICM1 corresponded to F.vesca pseudochromosome 7(Fv7),ICM4 to Fv4,ICM5 to Fv3,ICM6 to Fv2 and ICM7 to Fv5.Rose ICM2 corresponded to parts of F.vesca pseudochromosomes 1 and 6,whereas ICM3 is syntenic to the remainder of Fv6. | Mirjana Vukosavljev Paul Arens Roeland E Voorrips Wendy P C van't Westende G D Esselink Peter M Bourke Peter Cox W Eric van de Weg Richard G F Visser Chris Maliepaard Marinus J M Smulders | 2016 | Horticulture Research2016，3，1： | 6 |
| 15 | Genotyping-by-sequencing application on diploid rose and a resulting high-density SNP-based consensus map显示文摘Roses,which have been cultivated for at least 5000 years,are one of the most important ornamental crops in the world.Because of the interspecific nature and high heterozygosity in commercial roses,the genetic resources available for rose are limited.To effectively identify markers associated with QTL controlling important traits,such as disease resistance,abundant markers along the genome and careful phenotyping are required.Utilizing genotyping by sequencing technology and the strawberry genome(Fragaria vesca v2.0.a1)as a reference,we generated thousands of informative single nucleotide polymorphism(SNP)markers.These SNPs along with known bridge simple sequence repeat(SSR)markers allowed us to create the first high-density integrated consensus map for diploid roses.Individual maps were first created for populations J06-20-14-3דLittle Chief”(J14-3×LC),J06-20-14-3דVineyard Song”(J14-3×VS)and“Old Blush”דRed Fairy”(OB×RF)and these maps were linked with 824 SNPs and 13 SSR bridge markers.The anchor SSR markers were used to determine the numbering of the rose linkage groups.The diploid consensus map has seven linkage groups(LGs),a total length of 892.2 cM,and an average distance of 0.25 cM between 3527 markers.By combining three individual populations,the marker density and the reliability of the marker order in the consensus map was improved over a single population map.Extensive synteny between the strawberry and diploid rose genomes was observed.This consensus map will serve as the tool for the discovery of marker–trait associations in rose breeding using pedigree-based analysis.The high level of conservation observed between the strawberry and rose genomes will help further comparative studies within the Rosaceae family and may aid in the identification of candidate genes within QTL regions. | Muqing Yan David H.Byrne Patricia E.Klein Jizhou Yang Qianni Dong Natalie Anderson | 2018 | Horticulture Research2018，5，1： | 6 |
| 16 | Dissection of two quantitative trait loci for grain weight linked in repulsion on the long arm of chromosome 1 of rice(Oryza sativa L.)显示文摘Grain weight is a key determinant of grain yield in rice. Three sets of rice populations with overlapping segregating regions in isogenic backgrounds were established in the generations of BC2 F5, BC2 F6 and BC2 F7, derived from Zhenshan 97 and Milyang 46, and used for dissection of quantitative trait loci(QTL) for grain weight. Two QTL linked in repulsion phase on the long arm of chromosome 1 were separated. One was located between simple sequence repeat(SSR) markers RM11437 and RM11615, having a smaller additive effect with the enhancing allele from the maintainer line Zhenshan 97 and a partially dominant effect for increasing grain weight. The other was located between SSR markers RM11615 and RM11800, having a larger additive effect with the enhancing allele from the restorer line Milyang 46 and a partially dominant effect for increasing grain weight. When the two QTL segregated simultaneously, a residual additive effect with the enhancing allele from Milyang 46 and an over-dominance effect for increasing grain weight were detected. This suggests that dominant QTL linked in repulsion phase might play an important role in heterosis in rice. Our study also indicates that the use of populations with overlapping segregating regions in isogenic backgrounds is helpful for the dissection of minor linked QTL. | Liang Guo Kai Wang Junyu Chen Derun Huang Yeyang Fan Jieyun Zhuang | 2013 | The Crop Journal2013，1，1： | 6 |

| 18 | Interval mapping for red/green skin color in Asian pears using a modified QTL-seq method显示文摘Pears with red skin are attractive to consumers and provide additional health benefits.Identification of the gene(s)responsible for skin coloration can benefit cultivar selection and breeding.The use of QTL-seq,a bulked segregant analysis method,can be problematic when heterozygous parents are involved.The present study modified the QTL-seq method by introducing a|Δ(SNP-index)|parameter to improve the accuracy of mapping the red skin trait in a group of highly heterozygous Asian pears.The analyses were based on mixed DNA pools composed of 28 red-skinned and 27 green-skinned pear lines derived from a cross between the‘Mantianhong’and‘Hongxiangsu’red-skinned cultivars.The‘Dangshansuli’cultivar genome was used as reference for sequence alignment.An average single-nucleotide polymorphism(SNP)index was calculated using a sliding window approach(200-kb windows,20-kb increments).Nine scaffolds within the candidate QTL interval were in the fifth linkage group from 111.9 to 177.1 cM.There was a significant linkage between the insertions/deletions and simple sequence repeat markers designed from the candidate intervals and the red/green skin(R/G)locus,which was in a 582.5-kb candidate interval that contained 81 predicted protein-coding gene models and was composed of two subintervals at the bottom of the fifth chromosome.The ZFRI 130-16,In2130-12 and In2130-16 markers located near the R/G locus could potentially be used to identify the red skin trait in Asian pear populations.This study provides new insights into the genetics controlling the red skin phenotype in this fruit. | Huabai Xue Ting Shi Fangfang Wang Huangkai Zhou Jian Yang Long Wang Suke Wang Yanli Su Zhen Zhang Yushan Qiao Xiugen Li | 2017 | Horticulture Research2017，4，1： | 5 |
| 19 | The Belt and Road Initiative and the 2030 Agenda for Sustainable Development:seeking linkages for global environmental governance显示文摘Global environmental cooperation serves as an important part in the Chinese ideal of building a Community with a Shared Future for all Human Beings. The report of 19 th CPC National Congress indicates that China is committed to proactive mitigation under the Paris Agreement and further participating in global environmental governance under the 2030 Agenda for Sustainable Development, and both of which are largely integrated to the Belt and Road Initiative(BRI). BRI are also closely linked with South-South environmental and climate cooperation proposed by China from previous UN summits. Based on shared ideas, intersected agendas, and compatible governance approaches, BRI and the 2030 Agenda for Sustainable Development grow increasingly relevant and they might form synergies based on increasingly interactive relations. In sum,seeking and intensifying the linkages between BRI and 2030 sustainable development goals(SDGs) could address global environmental governance deficits and enhance cooperation among nations. | Liang Dong Xiaohua Yang Hongtao Li | 2018 | Chinese Journal of Population,Resources and Environment2018，16，3： | 5 |
