| 1 | 硬粒小麦与野生二粒小麦重组自交系群体穗部性状的QTL定位显示文摘野生二粒小麦是现代栽培小麦的祖先种,含有极为丰富的遗传多样性。本研究利用来自以色列Gitit的野生二粒小麦G18-16与来自欧洲的硬粒小麦栽培品种Langdon杂交构建的重组自交系F6代152个家系,进行了抽穗期、单株有效穗数、穗粒数、穗长、芒长等数量性状基因位点(QTL)分析,发现全部家系在5个性状上表现出宽广的遗传差异。14个穗部性状加性QTL被定位,LOD值为1.9~13.4,贡献率为7.3%~54.2%。控制抽穗期的QTL共3个,定位在3A(2个)和7B上;在2A(2个)和5A上共找到3个控制穗粒数的QTL;在5B上找到2个控制单株有效穗数的QTL;控制穗长的3个QTL分布在5A(2个)和7A上;在4B,5A和7A上共找到3个控制芒长的QTL。获得的QTL可用于今后分子标记辅助育种改良现代栽培小麦。 | 严俊 张玲玲 万兵 苟君波 王运长 许昌敏 Tzion Fahima 程剑平 | 2011 | 四川农业大学学报2011，29，2： | 8 |
| 2 | 四倍体小麦籽粒多组分营养物质含量的QTL定位及相关性分析显示文摘为了寻找改良普通栽培小麦营养物质含量的基因资源,以野生二粒小麦G18-16和硬粒小麦Langdon杂交所构建的重组自交系F6代群体为研究材料,种植于黔中地区并对该群体籽粒可溶性蛋白质、总类黄酮、总酚、植酸和黄色素5个营养性状含量进行测定。共检测到6个相关的QTLs,分别分布在染色体2A、3A、4A、6B和7A上。除小麦籽粒总酚性状外,其余四个性状均呈正态分布。网络相关性分析表明,所有营养性状与农艺性状间均呈显著负相关,仅黄色素与农艺性状无显著相关性。主成分分析(Principal component analysis,PCA)也显示总酚和黄色素与其他营养性状有显著差异,并且是造成群体分布差异最主要的因素。因此,小麦总酚和黄色素性状在其生理代谢中可能存在特殊性。另外,PCA还筛选出2组在5个营养性状上存在显著差异的基因池家系各4株,为回交和精细定位提供了较可靠的研究材料。 | 凡迪 薛文韬 严俊 赵钢 FAHIMA Tzion 程剑平 | 2014 | 麦类作物学报2014，34，12： | 6 |
| 3 | 小麦花后库源器官氮素、磷素营养物质积累动态分析显示文摘为探究小麦开花后不同部位氮素、磷素营养物质积累的动态规律,以中国春和贵紫1号2个小麦品种为材料,分别于花后5,15,25,35,45 d对小麦旗叶、茎鞘、颖壳穗轴和子粒中氨基酸、可溶性蛋白质、无机磷、植酸含量及单粒质量进行动态测定。结果表明,在子粒发育过程中,2个小麦品种库源器官氮素、磷素营养物质及单粒质量均有相似的变化趋势。除源器官的氨基酸和茎鞘的植酸外,其他氮素、磷素营养物质与子粒库中的5个营养性状均具有显著相关性。子粒发育中期库源器官氮素、磷素营养物质含量的差异远小于其前期与后期。结果还表明,小麦子粒发育中期(花后15~25 d)库源器官氮、磷代谢最为旺盛。建议此时期更应注重小麦氮、磷养分均衡,既满足子粒积累足够氮、磷营养,不致早衰,又同时注意防止其过量造成贪青晚熟,以保证小麦的优质高产。 | 梁勇 李大清 陈月星 程剑平 赵钢 FAHIMA Tzion 严俊 | 2019 | 河南农业大学学报2019，53，4： | 3 |

| 5 | Effects of Different Selenium Application Methods on Wheat (Triticum aestivum L.) Biofortification and Nutritional Quality显示文摘Mineral nutrient malnutrition,especially deficiency in selenium(Se),affects the health of approximately 1 billion people worldwide.Wheat,a staple food crop,plays an important role in producing Se-enriched foodstuffs to increase the Se intake of humans.This study aimed to evaluate the effects of different Se application methods on grain yield and nutritional quality,grain Se absorption and accumulation,as well as 14 other trace elements concentrations in wheat grains.A sand culture experiment was conducted via a completely randomized 3×2×1 factorial scheme(three Se levels×two methods of Se application,foliar or soil×one Se sources,selenite),with two wheat cultivars(Guizi No.1,Chinese Spring).The results showed that both foliar Se and soil Se application methods had effects on wheat pollination.Foliar Se application resulted in early flowering of wheat,while soil Se application caused early flowering of wheat at low Se levels(5 mg kg^(−1))and delayed wheat flowering at high selenium levels(10 mg kg^(−1)),respectively.For trace elements,human essential trace elements(Fe,Zn,Mn,Cu,Cr,Mo,Co and Ni)concentrations in wheat grains were dependent of Se applica-tion methods and wheat cultivars.However,toxic trace elements(Cd,Pb,Hg,As,Li and Al)concentrations can be decreased by both methods,indicating a possible antagonistic effect.Moreover,both methods increased Se concentrations,and improved grain yield and nutritional quality,while the foliar application was better than soil.Accordingly,this study provided useful information concerning nutritional biofortification of wheat,indicating that it is feasible to apply Se to conduct Se biofortification,inhibit the heavy metal elements concentrations and improve yield and quality in crops,which caused human health benefits. | Yong Liang Yuexing Chen Dong Liu Jianping Cheng Gang Zhao Tzion Fahima Jun Yan | 2020 | Phyton-International Journal of Experimental Botany2020，89，2： | 1 |

| 13 | Molecular mapping of YrTZ2,a stripe rust resistance gene in wild emmer accession TZ-2 and its comparative analyses with Aegilops tauschii显示文摘Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici(Pst), is a devastating disease that can cause severe yield losses. Identification and utilization of stripe rust resistance genes are essential for effective breeding against the disease. Wild emmer accession TZ-2, originally collected from Mount Hermon, Israel, confers near-immunity resistance against several prevailing Pst races in China. A set of 200 F_(6:7) recombinant inbred lines(RILs) derived from a cross between susceptible durum wheat cultivar Langdon and TZ-2 was used for stripe rust evaluation. Genetic analysis indicated that the stripe rust resistance of TZ-2 to Pst race CYR34 was controlled by a single dominant gene, temporarily designated YrTZ2. Through bulked segregant analysis(BSA) with SSR markers, YrTZ2 was located on chromosome arm 1 BS flanked by Xwmc230 and Xgwm413 with genetic distance of 0.8 cM(distal) and 0.3 cM(proximal), respectively. By applying wheat 90K iSelect SNP genotyping assay, 11 polymorphic loci(consisting of 250 SNP markers) closely linked to YrTZ2 were identified. YrTZ2 was further delimited into a 0.8-cM genetic interval between SNP marker IWB19368 and SSR marker Xgwm413, and cosegregated with SNP marker IWB28744(co-segregated with 28 SNP). Comparative genomics analyses revealed high level of collinearity between the YrTZ2 genomic region and the orthologous region of Aegilops tauschii 1 DS. The genomic region between loci IWB19368 and IWB31649 harboring YrTZ2 is orthologous to a 24.5-Mb genomic region between AT1D0112 and AT1D0150, spanning 15 contigs on chromosome 1 DS. The genetic and comparative maps of YrTZ2 provide a framework for map-based cloning and marker-assisted selection of YrTZ2. | WANG Zhen-zhong XIE Jing-zhong GUO Li ZHANG De-yun LI Gen-qiao FANG Ti-lin CHEN Yong-xing LI Jun WU Qiu-hong LU Ping LI Miao-miao WU Hai-bin ZHANG Huai-zhi ZHANG Yan YANG Wu-yun LUO Ming-cheng Fahima Tzion LIU Zhi-yong | 2018 | Journal of Integrative Agriculture2018，17，6： | 0 |
| 14 | Functional characterization of powdery mildew resistance gene MIIW172,a new Pm60 allele and its allelic variation in wild emmer wheat显示文摘Wild emmer wheat(Triticum dicoccoides,WEW)is an immediate progenitor of both the cultivated tetraploid and hexaploid wheats and it harbors rich genetic diversity against powdery mildew caused by Blumeria graminis f.sp.tritici(Bgt).A powdery mildew resistance gene Ml I^(W172)originated from WEW accession I^(W172)(G-797-M)is fine mapped in a 0.048 centimorgan(c M)genetic interval on 7 AL,corresponding to a genomic region spanning 233 kb,1 Mb and 800 kb in Chinese Spring,WEW Zavitan,and T.urartu G1812,respectively.Ml I^(W172)encodes a typical NLR protein NLRI^(W172)and physically locates in an NBS-LRR gene cluster.NLRI^(W172)is subsequently identified as a new allele of Pm60,and its function is validated by EMS mutagenesis and transgenic complementation.Haplotype analysis of the Pm60 alleles reveals diversifications in sequence variation in the locus and presence and absence variations(PAV)in WEW populations.Four common single nucleotide variations(SNV)are detected between the Pm60 alleles from WEW and T.urartu,indicative of speciation divergence between the two different wheat progenitors.The newly identified Pm60 alleles and haplotypes in WEW are anticipated to be valuable for breeding powdery mildew resistance wheat cultivars via marker-assisted selection. | Qiuhong Wu Yongxing Chen Beibei Li Jing Li Panpan Zhang Jingzhong Xie Huaizhi Zhang Guanghao Guo Ping Lu Miaomiao Li Keyu Zhu Wenling Li Tzion Fahima Eviatar Nevo Hongjie Li Lingli Dong Zhiyong Liu | 2022 | Journal of Genetics and Genomics2022，49，8： | 0 |
