2023年11月27日 · Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), poses a threat to global wheat production. Deployment of widely effective resistance genes underpins management of this ongoing threat. This study focused on the mapping of stripe rust resistance gene YR63 from a Portuguese hexaploid wheat landrace AUS27955 of the Watkins Collection.

YR63 exhibits resistance to a broad spectrum of Pst races from Australia, Africa, Asia, Europe, Middle East and South America. It was mapped to the short arm of chromosome 7B, between two single nucleotide polymorphic (SNP) markers sunCS_YR63 and sunCS_67, positioned at 0.8 and 3.7 Mb, respectively, in the Chinese Spring genome assembly v2.1.

一项名为“Wheat stripe rust resistance locus YR63 is a hot spot for evolution of defence genes - a pangenome discovery”的研究揭示了一种新的小麦抗条锈病的基因，命名为YR63。 该基因位于小麦第7B染色体的短臂上，能够抵抗来自澳大利亚、非洲、亚洲、欧洲、中东和南美洲的多种条锈病菌株。 研究人员使用了多种方法，包括基因组测序、RNA测序和比较基因组分析等，对YR63进行了详细的研究。 研究人员还发现，在基因簇中，YR63位于一个富含多种核苷酸结合和亮氨酸 …

2023年11月27日 · We characterised YR63 locus using an integrated approach engaging targeted genotyping-by-sequencing (tGBS), mutagenesis, resistance gene enrichment and sequencing (MutRenSeq), RNA sequencing (RNASeq) and comparative genomic analysis with tetraploid (Zavitan and Svevo) and hexaploid (Chinese Spring) …

2017年4月5日 · Yr6 and Yr63 are located on the short arm of chromosome 7B (El-Bedewy and Robbelen 1982; McIntosh et al. 2014), a different chromosomal arm from YrLk. The Yr6 near-isogenic line AvSYr6NIL and Yr6 carrier cultivars Heines Peko and Heines Kolben (Calonnec et al. 1997) were susceptible to Pst race Sun11-11 in our greenhouse test, while YrLk is ...

2022年1月26日 · Markers for many seedling stripe rust resistance genes, including Yr47 , Yr51 , Yr57 , Yr63 , Yr81 , and Yr82 , as well as adult plant resistance genes Yr18 , Yr36 , and Yr46 , have been reported. Similarly, markers for several …

2017年8月4日 · Yr63 has been mapped to the short arm of 7B chromosome (McIntosh et al., 2013). Based on the relative genetic position of Yr63 in the integrated genetic map constructed by [ 24 ], IWA3506 was mapped at an average genetic distance of 30.0 cM from Yr63 , which indicates that IWA3506 is likely different from Yr63 , and thus represents a newly ...
