Apr 17, 2024 · Sequencing of putative Yr10 mutants by Ni et al. identified changes in a gene named YrNAM that was closely linked to gene Yr10 CG, reported earlier as the Yr10 candidate.

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.

Dec 1, 2014 · 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.

Oct 6, 2014 · 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；26 号材料中可能含有与 Yr10 基因第二外显子序列相似的抗性基因 ...

小麦条锈病是由条形柄锈菌(Puccinia striiformis f.sp.tritici)引起的一类真菌病害,严重威胁我国小麦的生产.条形柄锈菌气流传播并且小种变异频繁,所以小麦条锈病的防治一直处于被动状态.大量的生产实践和科研表明,培育和种植对条锈病具有抗性的小麦是最经济安全和 ...

通过病毒诱导基因沉默（VIGS）系统对候选基因进行功能分析，发现基因 TaHPPD （4-羟苯基丙酮酸双加氧酶）通过影响SA信号传导负调控小麦对条锈病的抗性， 与发病机制相关。 PR ) 基因表达和 ROS 清除。 我们的研究深入了解了 Yr10 介导的小麦抗性。 Stripe rust, caused by Puccinia striiformis f. sp. tritici), is a catastrophic disease that threatens global wheat yield. is a race-specific all-stage disease resistance gene in wheat.

May 26, 2021 · 摘要：小麦抗条锈病基因Yr10作为全生育期抗性基因,对国内大部分的条锈菌生理小种表现抗性,为探究Yr10介导的抗病通路,以小麦AvocetS (AvS)和其近等基因系AvS Yr10NIL (AvS+ Yr10)为材料,接种条锈菌CYR31后分别构成亲和与非亲和体系,通过分析含有抗病基因Yr10非亲和体系中的信号分子变化,比较非亲和与亲和体系中抗病过程相关基因的表达差异和功能,进而解析Yr10的抗病通路.结果 表明,在含有抗病基因Yr10的非亲和体系中,RAR1、HSP90和SGT1可能 …

小麦条锈病是由小麦条锈菌(Puccinia striiformisf. sp.tritici)引起的一种重要真菌病害,对我国小麦生产带来重要威胁.与化学防控相比,利用抗病基因及选育抗病品种是控制小麦条锈病最为经济,有效的途径.小麦抗条锈病基因 Yr10 是一个全生育期抗病基因(ASR),对我国目前 ...

In order to determine the distribution of stripe rust resistance genes Yr5, Yr10 and Yr18 among 348 wheat germplasms which were collected from many breeding units all over the country, their co-segregated or closely linked molecular markers S1320, SC200 and csLV34 were ...

小麦条锈病是一种世界性病害,严重威胁着小麦生产,目前尚未发现成 功克隆小麦抗锈基因的文献报道.小麦抗条锈病基因Yr10可抵抗我国目前出 现的所有条锈菌生理小种,而且在生产上还基本没有被利用.因此,本文以Yr10 的载体品种Moro作材料,首次应用差异显示RT-PCR ...
