| 1 | Mapping QTLs with epistatic effects and QTL×environment interactions for plant height using a doubled haploid population in cultivated wheat显示文摘Quantitative trait loci (QTLs) for plant height in wheat (Triticum aestivum L.) were studied using a set of 168 doubled haploid (DH) lines, which were derived from the cross Huapei 3/Yumai 57. A genetic linkage map was constructed using 283 SSR and 22 EST-SSR markers. The DH population and the parents were evaluated for wheat plant height in 2005 and 2006 in Tai’an and 2006 in Suzhou. QTL analyses were performed using the software of QTLNetwork version 2.0 based on the mixed linear model. Four additive QTLs and five pairs of epistatic effects were detected, which were distributed on chromosomes 3A, 4B, 4D, 5A, 6A, 7B, and 7D. Among them, three additive QTLs and three pairs of epistatic QTLs showed QTL×environment interactions (QEs). Two major QTLs, Qph4B and Qph4D, which accounted for 14.51% and 20.22% of the phenotypic variation, were located similar to the reported locations of the dwarfing genes Rht1 and Rht2, respectively. The Qph3A-2 with additive effect was not reported in previous linkage mapping studies. The total QTL effects detected for the plant height explained 85.04% of the phenotypic variation, with additive effects 46.07%, epistatic effects 19.89%, and QEs 19.09%. The results showed that both additive effects and epistatic effects were important genetic bases of wheat plant height, which were subjected to environmental modifications, and caused dramatic changes in phenotypic effects. The information obtained in this study will be useful for manipulating the QTLs for wheat plant height by molecular marker-assisted selection (MAS). | Kunpu Zhang Jichun Tian Liang Zhao Shanshan Wang | 2008 | Journal of Genetics and Genomics2008，35，2： | 36 |
| 2 | Dissecting and Enhancing the Contributions of High-Molecular-Weight Glutenin Subunits to Dough Functionality and Bread Quality显示文摘Dear Editor, Seed storage proteins (SSPs) are frequently important determinants of crop quality traits (Shewry and Casey,1999).Dissecting and enhancing the genetic contributions of individual SSPs to their target traits are essential for effectively improving crop quality attributes.However,such a task is often difficult to accomplish,because SSPs are frequently expressed from multigene families and exhibit strong allelic variation.Consequently,detailed knowledge of the function of individual SSPs in crop quality trait is still limited.This scenario is well illustrated by high-molecular-weight glutenin subunits (HMWGSs),a complex family of SSPs that are involved in wheat enduse quality through affecting dough functionality (Békés,2012;Rasheed et al.,2014). | Yiwen Li Xuefi An Ran Yang Xiaomin Guo Guidong Yue Renchun Fan Bin Li Zhensheng Li Kunpu Zhang Zhenying Dong Luyan Zhang Jiankang Wang Xu Jia Hong-Qing Ling Aimin Zhang Xiangqi Zhang Daowen Wang | 2015 | Molecular Plant2015，8，2： | 9 |
| 3 | Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world. | Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong | 2022 | Science China(Life Sciences)2022，65，9： | 9 |
| 4 | Assessment of the individual and combined effects of Rht8 and Ppd-D1a on plant height, time to heading and yield traits in common wheat显示文摘Grain yield in cereal crops is a complex trait controlled by multiple genes and influenced by developmental processes and environment. Here we report the effects of alleles Rht8 and Ppd-D1 a on plant height, time to heading, and grain yield and its component traits. Association analysis and quantitative trait locus mapping using phenotypic data from 15 environments led to the following conclusions. First, both Rht8 and Ppd-D1 a reduce plant height. However, Ppd-D1 a but not Rht8 causes earlier heading.Second, both Rht8 and Ppd-D1 a promote grain yield and affect component traits. Their combined effects are substantially larger than those conferred by either allele alone.Third, promotion of grain yield by Rht8 and Ppd-D1 a is through increasing fertile spikelet number. We speculate that Rht8 and Ppd-D1 a act independently and additively in control of plant height, grain yield and yield component. Combination of the two alleles is desirable for adjusting plant height and enhancing grain yield and abiotic stress tolerance. | Kunpu Zhang Junjun Wang Huanju Qin Zhiying Wei Libo Hang Pengwei Zhang Matthew Reynolds Daowen Wang | 2019 | The Crop Journal2019，7，6： | 5 |
| 5 | Conditional QTL mapping of three yield components in common wheat(Triticum aestivum L.)显示文摘Spike number per m^2(SN),kernel number per spike(KNPS) and thousand-kernel weight(TKW)are the three main components determining wheat(Triticum aestivum L.) yield.To evaluate the relationships among them a doubled haploid(DH) population consisting of 168 lines grown at three locations for three years was analyzed by unconditional and conditional QTL mapping.Thirty-three unconditional QTL and fifty-nine conditional QTL were detected.Among them,two QTL(QSN-DH-2B and QSN-DH-3A-1.1) improved SN,with no effect on KNPS.QKNPS-DH-2B-2.1 improved KNPS,with no effect on SN.QKNPS-DH-1A-1.1,QKNPS-DH-2D-1.1and QKNPS-DH-6A improved KNPS,with no effect on SN or TKW.QKNPS-DH-6B was associated with increased SN and TKW.In addition,QTKW-DH-4B,QTKW-DH-5B and QTKW-DH-7B increased TKW without decreasing KNPS.These results provide useful information for marker assisted selection(MAS) and improvement in wheat yield. | Han Zhang Jiansheng Chen Ruyu Li Zhiying Deng Kunpu Zhang Bin Liu Jichun Tian | 2016 | The Crop Journal2016，4，3： | 5 |
| 6 | Molecular genetic and genomic analysis of wheat milling and end-use traits in China:Progress and perspectives显示文摘Wheat is the most widely cultivated staple food crop, and multiple types of food derivatives are processed and consumed globally. Wheat grain quality(WGQ) is central to food processing and nutritional value, and is a decisive factor for consumer acceptance and commercial value of wheat cultivars. Hence, improvement in WGQ traits is top priority for both conventional and molecular wheat breeding. In this review we will focus on two important WGQ traits, grain milling and end-use, and will summarize recent progress in China. Chinese scientists have invested substantial effort in molecular genetic and genomic analysis of these traits and their effects on end-use properties. The insights and resources generated have contributed to the understanding and improvement of these traits. As high-quality genomics information and powerful genome engineering tools are becoming available for wheat, more fundamental breakthroughs in dissecting the molecular and genomic basis of WGQ are expected. China will strive to make further significant contributions to the study and improvement of WGQ in the genomics era. | Daowen Wang Kunpu Zhang Lingli Dong Zhenying Dong Yiwen Li Abrar Hussain Huijie Zhai | 2018 | The Crop Journal2018，6，1： | 4 |
| 7 | Genetic Analysis of Chromosomal Loci Affecting the Content of Insoluble Glutenin in Common Wheat显示文摘In common wheat, insoluble glutenin(IG) is an important fraction of flour glutenin macropolymers, and insoluble glutenin content(IGC)is positively associated with key end-use quality parameters. Here, we present a genetic analysis of the chromosomal loci affecting IGC with the data collected from 90 common wheat varieties cultivated in four environments. Statistical analysis showed that IGC was controlled mainly genetically and influenced by the environment. Among the major genetic components known to affect end-use quality,1BL/1RS translocation had a significantly negative effect on IGC across all four environments. As to the different alleles of Glu-A1,-B1 and-D1 loci, Glu-A1 a, Glu-B1 b and Glu-D1 d exhibited relatively strong positive effects on IGC in all environments. To identify new loci affecting IGC, association mapping with 1355 DAr T markers was conducted. A total of 133 markers were found associated with IGC in two or more environments(P < 0.05), ten of which consistently affected IGC in all four environments. The phenotypic variance explained by the ten markers varied from 4.66% to 8.03%, and their elite alleles performed significantly better than the inferior counterparts in enhancing IGC. Among the ten markers, w Pt-3743 and w Pt-733835 reflected the action of Glu-D1, and w Pt-664972 probably indicated the effect of Glu-A1. The other seven markers, forming three clusters on 2AL, 3BL or 7BL chromosome arms, represented newly identified genetic determinants of IGC. Our work provided novel insights into the genetic control of IGC, which may facilitate wheat enduse quality improvement through molecular breeding in the future. | Huaibing Jin Zhaojun Wang Da Li Peipei Wu Zhengying Dong Chaowu Rong Xin Liu Huanju Qin Huili Li Daowen Wang Kunpu Zhang | 2015 | Journal of Genetics and Genomics2015，42，9： | 3 |

| 11 | A new phase of treasure hunting in plant genebanks显示文摘The United Nations has estimated that the world population will surpass 8 billion on Nov.15,2022,and will continue to rise to 11.2 billion by 2100.Considering that agricultural resources are limited,it will be a huge challenge to produce sufficient food to feed such a rapidly rising global population.Furthermore,the ongoing climate changes are adding more pressures on worldwide crop productions.To cope with these problems,it is both imperative and urgent to develop the crop cultivars with higher yield potential,improved nutritional quality,and better resilience to environmental stresses. | Guangwei Li Zhiyong Wang Yuxuan Meng Zheng Qing Fu Daowen Wang Kunpu Zhang | 2023 | Molecular Plant2023，16，3： | 0 |
| 12 | Reactions of Triticum urartu accessions to two races of the wheat yellow rust pathogen显示文摘Triticum urartu(AA,2n=2x=14),a wild grass endemic to the Fertile Crescent(FC),is the progenitor of the A subgenome in common wheat.It belongs to the primary gene pool for wheat improvement.Here,we evaluated the yellow rust(caused by Puccinia striiformis f.sp.tritici,Pst)reactions of 147 T.urartu accessions collected from different parts of the FC.The reactions varied from susceptibility to strong resistance.In general,there were more accessions with stronger resistance to race CYR33 than to CYR 32.In most cases the main form of defense was a moderate resistance characterized by the presence of necrotic/chlorotic lesions with fewer Pst uredinia on the leaves.Forty two accessions displayed resistance to both races.Histological analysis showed that Pst growth was abundant in the compatible interaction but significantly suppressed by the resistant response.Gene silencing mediated by Barley stripe mosaic virus was effective in two T.urartu accessions with different resistance responses,indicating that this method can expedite future functional analysis of resistance genes.Our data suggest that T.urartu is a valuable source of resistance to yellow rust,and represents a model for studying the genetic,genomic and molecular basis underlying interaction between wheat and Pst. | Jibin Xiao Lingli Dong Huaibing Jin Juncheng Zhang Kunpu Zhang Na Liu Xinyun Han Hongyuan Zheng Wenming Zheng Daowen Wang | 2018 | The Crop Journal2018，6，5： | 0 |
