2021年7月5日 · High-temperature wheat leaf rust resistance gene Lr13 exhibits pleiotropic effects on hybrid necrosis Mol Plant . 2021 Jul 5;14(7):1029-1032. doi: 10.1016/j.molp.2021.05.009.

2021年7月5日 · In summary, we isolated the high-temperature leaf rust resistance gene LrZH22/Lr13 from the elite wheat cultivar Zhoumai 22 using map-based cloning, MutRenSeq, EMS mutagenesis, transgenic validation, and haplotype analysis. Independent cloning and genetic analysis revealed that els1/Ne2 is the same as LrZH22/Lr13.

2021年7月5日 · Wheat leaf rust resistance gene Lr13 is a specific Ne2 allele for hybrid necrosis. Wheat leaf rust resistance gene Lr13 is a specific Ne2 allele for hybrid necrosis Mol Plant. 2021 Jul 5;14(7):1025-1028. doi: 10.1016/j.molp.2021.05.010. Epub 2021 …

2021年7月5日 · Lr13 is regarded as one of the most widely distributed leaf rust R genes in wheat (McIntosh et al., 1995). Researchers observed that lines carrying Lr13 consistently gave hybrid necrosis in specific crosses.

Ne2 shows extremely tight genetic linkage with leaf rust resistance gene Lr13 (Zhang et al., 2016). We previously identified a temperature-sensitive leaf rust resistance gene LrZH22 in Chinese wheat cultivar Zhoumai 22 (ZM, Figure 1A) that was effective against most Chinese Pt pathotypes (Wang et al., 2016) and shared an overlapping genetic ...

2015年12月10日 · Lr13 contributed negligible resistance singly, but every year the combination of Lr13 and Lr34 showed synergistic resistance (McCallum unpublished data). Given the presence of Lr13 in Canadian germplasm, closely linked DNA markers are desirable for marker-assisted selection and characterization of germplasm and parental material.

Genetic and mutational analyses of wheat leaf rust resistance gene Lr13 and hybrid necrosis gene Ne2 m indicated that they are the same gene. Hybrid necrosis in wheat characterized by chlorosis and eventual necrosis of plant tissues in certain wheat hybrids is controlled by the interaction of comple …

results indicated that LrZH22/Lr13 is a high-temperature leaf rust resistance gene likely influenced by genetic background. Another possibility is the presence of an enhancer in ZM.

In wheat, Lr13, first identified in the Canadian cultivar “Manitou” in 1966, is an important adult-plant leaf rust resistance gene (McIntosh et al., 1995) that is widely found in wheat cultivars (e.g., ‘Frontana,’ ‘Frondoso,’ and ‘Fronteria’) and used in many breeding programs throughout the world (Roelfs, 1988; Pathan and Park ...

2022年3月14日 · We identified the race-specific disease resistance gene Yr27, which encodes an intracellular immune receptor, to be a major contributor to this resistance. Yr27 is allelic to the leaf rust...
