WebMar 1, 2024 · Mining powdery mildew resistance genes in wheat cultivars and their appliance in breeding program is a promising way to control this dis- ease. Genetic analysis revealed that a single dominant resistance gene named PmTm4 originated from Chinese wheat line Tangmai 4 confers resistance to prevailing isolates of B. graminis f. sp. tritici … WebFeb 25, 2024 · Six wheat genotypes with documented Pm genes at locus Pm5, including CI14125 with Pm5a, Aquila with Pm5b, FZ30 with Pm5e, Xiaobaidongmai with mlxbd, Hongquanmang with PmH, and Hongyoumai with Pmhym, were used to compare their reaction patterns to different Blumeria graminis f. sp. tritici isolates with that of DGM.

WebFeb 15, 2024 · Powdery mildew, which is caused by Blumeria graminis f. sp. tritici (Bgt), is a disease of wheat worldwide. Xiaobaidong is a Chinese wheat landrace, which still maintains good resistance against powdery mildew. To obtain more genetic markers closely linked to the powdery mildew resistance gene mlxbd and narrow the candidate region for its … WebPm5e were identified in different Chinese wheat landraces. Pm5e encodes a nucleotide-binding domain leucine-rich-repeat (NLR) containing protein, and the functional markers … WebJul 4, 2007 · All wheats carrying a Pm5 allele as the only resistance factor were resistant to Bgt pathotypes 10 and 14; however, a differential response to other isolates, especially 2, 5, 9, 13, 71, 77 and E, allowed identification of each allele by a unique reaction pattern. Lines IGV1-455 and IGV1-556 carrying Pm5d were resistant to all isolates. green bottle hairspray
