摘要：
Powdery mildew (Pm), caused by Blumeria graminis f. sp. tritici (Bgt), is one of the most serious diseases of common wheat (Triticum aestivum L.) in many regions of the world. Rapid loss of resistance caused by pathogen virulence requires continual improvement of Pm resistance through utilization of novel resistance genes. Pm07J126, in wheat line 07jian126, is a dominant resistance gene, conferring immunity to the prevailing Bgt population in Sichuan province. Previous studies showed that Pm07J126 might be derived from rye (Secale cereale L.) and that it was closely linked with SSR marker barc183. In this study, we localized Pm07J126 to the distal end of chromosome 6DS based on markers barc183 and cfd135. Collinearity analysis of wheat, Brachypodium and rice helped to identify an sequence tagged site marker in close proximity to barc183 in chromosome bin 6DS6-0.99-1.00. Marker Xcib9 that co-segregated with Pm07J126 should be useful for marker-assisted selection in wheat breeding programs.
