Publication - QTL mapping of adult-plant resistance to leaf rust in the wheat cross Zhou 8425B/Chinese spring using high-density SNP markers(Frontiers, 2017) Peipei Zhang; Guihong Yin; Aiyong Qi; Fengmei Gao; Xianchun Xia; He Zhonghu; Zaifeng Li; Daqun LiuWheat leaf rust is an important disease worldwide. Growing resistant cultivars is an effective means to control the disease. In the present study, 244 recombinant inbred lines from Zhou 8425B/Chinese Spring cross were phenotyped for leaf rust severities during the 2011-2012, 2012-2013, 2013-2014, and 2014-2015 cropping seasons at Baoding, Hebei province, and 2012-2013 and 2013-2014 cropping seasons in Zhoukou, Henan province. The population was genotyped using the high-density Illumina iSelect 90K SNP assay and SSR markers. Inclusive composite interval mapping identified eight QTL, designated as QLr.hebau-2AL, QLr.hebau-2BS, QLr.hebau-3A, QLr.hebau-3BS, QLr.hebau-4AL, QLr.hebau-4B, QLr.hebau-5BL, and QLr.hebau-7DS, respectively. QLr.hebau-2BS, QLr.hebau-3A, QLr.hebau-3BS, and QLr.hebau-5BL were derived from Zhou 8425B, whereas the other four were from Chinese Spring. Three stable QTL on chromosomes 2BS, 4B and 7DS explained 7.5-10.6%, 5.5-24.4%, and 11.2-20.9% of the phenotypic variance, respectively. QLr.hebau-2BS in Zhou 8425B might be the same as LrZH22 in Zhoumai 22; QLr.hebau-4B might be the residual resistance of Lr12, and QLr.hebau-7DS is Lr34. QLr.hebau-2AL, QLr.hebau-3BS, QLr.hebau-4AL, and QLr.hebau-5BL are likely to be novel QTL for leaf rust. These QTL and their closely linked SNP and SSR markers can be used for fine mapping, candidate gene discovery, and marker-assisted selection in wheat breeding.
Publication - Fine mapping of leaf rust resistance gene Lrzh84 using expressed sequence tag and sequence-tagged site markers, and allelism with other genes on wheat chromosome 1b(American Phytopathological Society (APS), 2013) Yue Zhou; Xianchun Xia; He Zhonghu; Xing Li; Zaifeng Li; Daqun LiuZhou 8425B, possessing the leaf rust resistance gene LrZH84, is an elite wheat (Triticum aestivum) parental line in the Yellow-Huai Valley region of China. In the present study, 2,086 F2 plants derived from Zhou 8425B/Chinese Spring were used for fine mapping of LrZH84 with expressed sequence tag (EST) and sequence-tagged site (STS) markers. Seventy inter-simple sequence repeat EST and STS markers on 1BL were used to screen the two parents and resistant and susceptible bulks; those polymorphic were used to analyze the entire F2 population. Three EST markers (BF474863, BE497107, and CD373538) were closely linked to LrZH84, with genetic distances of 0.7, 0.7, and 1.7 cM, respectively. STS marker Hbsf-1 was developed from the sequences of polymerase chain reaction fragments amplified from EST marker BF474863. LrZH84 was 8.19 cM proximal to Lr44, but may be allelic to LrXi and LrG98 although they showed different reactions with some Puccinia triticina pathotypes.

Publication - Seedling and slow rusting resistances to leaf rust in CIMMYT wheat lines(Institute of Crop Sciences, 2011) Han Ye; He Zhonghu; Xianchun Xia; Xing Li; Zaifeng Li; Daqun LiuCIMMYT wheat has played an important role in wheat breeding in China. Identification of leaf rust resistance genes in CIMMYT wheat is important for developing wheat cultivars with resistance to leaf rust in China. A total of 103 CIMMYT wheat lines and a set of 35 differential lines, mostly near-isogenic lines in the background of Thatcher with known leaf rust resistance genes were inoculated with 15 Chinese pathotypes of Puccinia triticina for postulating leaf rust resistance genes in CIMMYT wheats at the seedling stage. These genotypes were also planted in the field for characterization of slow rusting responses to leaf rust in the 2008?2009 and 2009?2010 cropping seasons.Four leaf rust resistance genes Lr26, Lr34, Lr42, and Lr47 were postulated in 46 genotypes through seedling test, pedigree analysis and molecular maker detection. Resistance gene Lr26 was present in nine accessions. Lr34 was identified in 28 lines. Lr42 was found in eleven lines and two lines might contain Lr47. Known resistance genes were not identified in the other 57 accessions and these lines were resistant to most of pathotypes tested. Forty-six genotypes showed slow leaf rusting resistance in the two cropping seasons. The results from seedling and field tests showed that CIMMYT wheats carry abundant effective seedling and adult plant resistance genes, and can be used in breeding resistant cultivars for durable control of wheat leaf rust in China.
Publication - Mapping of wheat stripe rust resistance gene YrZH84 with RGAP markers and its application(Institute of Crop Sciences, 2009) Guihong Yin; Wang Jian-Wu; Wen W.E.; He Zhonghu; Zaifeng Li; Wang Hui; Xianchun XiaZhou 8425B, with an effective stripe rust resistance gene YrZH84, is a hall-mark parent line of wheat (Triticum aestivum L.) in the Yellow-Huai Rivers wheat growing region. An F2 population derived from the cross Zhou 8425B/Chinese Spring and their parents were used for polymorphism analysis employing the resistance gene-analog polymorphism (RGAP) markers and bulked segregant analysis (BSA) based on marker genotypes and phenotypes selection. An RGAP marker Xrga-1 was identified, which was tightly linked to the stripe rust resistance gene YrZH84, with a genetic distance of 0.8 cM. The fragment amplified by Xrga-1 was 343 bp. BLAST analysis indicated that the rga-1 showed 93% of identical nucleotide sequences to barley stem rust resistance gene Rpg1, and 92% to barley powdery mildew resistance gene Mla homology family. Fifty-eight cultivars from Yellow-Huai rivers wheat growing region were genotyped by the RGAP marker Xrga-1. From the information of genotypes, pedigrees and resistance responses, the cultivars Zhoumai 11, Zhoumai 20, Zhoumai 22, Aikang 58, 04 Zhong 36, Yuanyu 3, 05 Zhong 37, Wankang 18, and Yuzhan 10 were identified to carry the resistance gene YrZH84. These cultivars were the derivatives of Zhou 8425B. These results will greatly benefit the marker-assisted selection in wheat and cloning of the resistance gene YrZH84.
