The first seedling or all-stage resistance (R) R gene against stripe rust isolated from Moro wheat (Triticum aestivum L.) using a map-based cloning approach was identified as Yr10. Clone 4B of this gene encodes a highly evolutionary-conserved and unique CC-NBS-LRR sequence.

2018年2月23日 · The stripe rust resistance gene Yr10 confers the race-specific resistance to most tested Pst races in China including CYR29. Early studies proposed that Yr10 was a nucleotide-binding site, leucine-rich repeat gene archived as GenBank accession AF149112 (hereafter designated the Yr10 candidate gene or Yr10 CG ).

2008年7月18日 · Yellow rust resistance locus Yr10 located on chromosome 1B in Moro and originated from the Turkish line PI178383 was investigated in terms of polymorphism in seven winter type bread wheat cvs.

2014年12月1日 · In the present study, we demonstrated that an expressed genomic sequence from chromosome 1B (clone 4B) constitutes the stripe rust resistance gene Yr10. Clone 4B represents a novel CC–NBS–LRR sequence and its presence in cultivars possessing Yr10 and in lines segregating for this gene was demonstrated.

2024年12月12日 · The presence of the Yr10 gene was conclusively confirmed by the EST-SSR marker E1, which displayed a distinct 754 bp band (Fig. 7). Monogenic segregation was observed at the E1 locus in BC 3 F 1 plants, with a 3:1 ratio in BC 3 F 2 plants (Table S1 ).

2012年11月20日 · Up to date, the three known loci Yr10, Yr18 and Yr36 are still effective for stripe rust resistance. However, economic and robust molecular markers are lacking for these loci, and their deployment in Chinese wheat is largely unknown.

【摘 要】Yr10基因是目前尚未被大面积应用的小麦条锈病抗性改良的良好基因源.以抗性水平不同的小麦品种及其近缘种共28份材料,进行Yr10第二外显子区功能标记开发的可行性探索,结果表明:本研究所用的小麦抗性材料中不含有Yr10基因,其抗性由其他抗性基因决定 ...

The dominant gene Yr10 was originally found in Turkish wheat line P.I.178383 (Temel et al 2008). Microsatellite marker Xpsp3000 was found linked to Yr10 gene at a genetic distance estimated at 1.2 cM (Wang et al to be highly resistant to more than 20 stripe rust races from six countries (Gerechter-Amitai and Stubbs 1970).

2024年8月1日 · Yr10 was allegedly cloned as a gene encoding a CC-NBS-LRR protein conferring resistance to North American Pst isolate SRC-84 [11], whereas a completely linked gene named YrNAM with an apparent identical specificity encodes a protein with a NAM domain and a ZnF-BED domain, effective against several Chinese Pst races [12].

2014年7月23日 · The first seedling or all-stage resistance R gene against stripe rust in wheat was identified as Yr10. This constitutively expressed gene encodes a unique CC–NBS–LRR sequence in wheat. However, highly evolutionary-conserved homologs were identified in many different monocot species.
