Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster located in a distal region of chromosome 7AL that has suppressed genetic recombination. A nucleotide-binding, leucine-rich repeat (NLR) immune receptor gene was isolated using mutagene …

2020年11月11日 · Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster located in a distal region of chromosome 7AL that has suppressed genetic recombination. A nucleotide-binding, leucine-rich repeat (NLR) immune receptor gene was isolated using mutagenesis and R gene enrichment sequencing (MutRenSeq).

Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster that resides in a distal region of chromosome 7A with suppressed genetic recombination due to unknown causes.

2023年2月11日 · Pm1a encodes a typical NLR protein that triggers a hypersensitive immune reaction upon recognition of the pathogen-derived effector protein encoded by the avirulence (Avr) gene AvrPm1a, which was also cloned using a B. graminis bi …

2020年12月15日 · Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster located in a distal region of chromosome 7AL that has suppressed genetic recombination. A nucleotide‐binding, leucine‐rich repeat (NLR) immune receptor gene was isolated using mutagenesis and R gene enrichment sequencing (MutRenSeq).

2023年8月22日 · Stable transformation of Pm1a confers a strong resistance in susceptible cv. Fielder and heterologous co-expression of Pm1a and AvrPm1 proved their receptor–effector relation. Interestingly, through phylogenetic analysis and the terminal chromosome arm 7AL rearrangement, Pm1a is closer to D. villosum -derived Pm21 at the evolutionary level.

2023年7月28日 · 病虫害对小麦产量降低约20%，谷物锈病 (锈菌属)和霉病 (蓝霉属)病原体具有高度的宿主特异性，与少数宿主物种共同进化。 由小麦黑麦病 (Pst)引起的条锈病和由小麦黑麦病 (Pt)引起的叶锈病可导致易感品种损失高达50%。 单一栽培和气候变化有利于出现新的高毒力病原体变种，从而降低产量，对全球粮食安全构成严重威胁。 虽可通过杀菌剂进行防治，但其产生的选择压力易使病原体突变产生抗药性，且存在昂贵、环境不友好等缺陷。 以往研究人员曾对病 …

2017年9月18日 · Pm1a was the first PM resistance gene identified on the long arm of chromosome 7A from a Canadian wheat cultivar Axminster 13, 14, 15, 16, 17. Since then, other genes have been identified...

Pm1a 编码一种典型的 NLR 蛋白，该蛋白在识别由无毒力 ( Avr ) 基因 AvrPm1a 编码的病原体衍生效应蛋白后触发超敏免疫反应，该基因也使用 禾本科 双亲作图群体进行了克隆（Hewitt 等人，2016 年） 。 , 2021 年）。 在该研究中， Bgt中的Pm1a 毒力表型与 AvrPm1a 中的五个单核苷酸多态性 (SNP) 相关，其中四个是非同义的。

Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster located in a distal region of chromosome 7AL that has suppressed genetic recombination. nucleotide-binding, leucine-rich repeat (NLR) immune receptor gene was isolated using mutagenesis and R gene enrichment sequencing (MutRenSeq).
