“…Therefore, marker cfd135 was closely linked with Pm07J126. Based on the present work and previous knowledge (Yu et al 2012), we identified SSR markers barc183 and cfd315 closely linked to Pm07J126. According to information on the two SSR markers (Somers et al 2004), Pm resistance gene Pm07J126 might be localized on the distal end of the wheat chromosome 6DS (Fig.…”

“…CM39, and CN19 were highly susceptible (IT 3-4), whereas 07jian126 and KS93WGRC28 (containing Pm20) were immune (IT 0) ( Table 1). F 2 segregation ratios were consistent with expected 3:1 ratios (Yu et al 2012). Localization of Pm07J126 with SSR markers Eight wheat SSR markers were examined for polymorphism between the parents and the resistant and susceptible bulks each comprising ten resistant and ten susceptible F 2 individuals.…”

“…The STS marker Xcib9 can be used in MAS of Pm07J126 in breeding programs. Although previous tests indicated that Pm07J126 might be different from the rye-derived Pm genes Pm7, Pm8, Pm17 and PmJZHM2RL (Yu et al 2012), its actual origin remains unknown. Pm07J126 conferred a high level of resistance similar to line KS93WGRC28 (Pm20) to 21 Bgt isolates (Yu et al 2012), but it is currently not possible to distinguish the two genes by pathogenicity tests.…”

“…The wheat line 07jian126 is highly resistant to Pm at all growth stages and its resistance is controlled by a single dominant gene, designated as Pm07J126, which might be derived from rye (Yu et al 2012). SSR marker barc183 was closely linked to Pm07J126.…”

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.

Powdery mildew is one of the serious diseases of wheat (Triticum aestivum L., 2 n = 6 × = 42, genomes AABBDD). Rye (Secale cereale L., 2 n = 2 × = 14, genome RR) offers a rich reservoir of powdery mildew resistant genes for wheat breeding program. However, extensive use of these resistant genes may render them susceptible to new pathogen races because of co-evolution of host and pathogen. Therefore, the continuous exploration of new powdery mildew resistant genes is important to wheat breeding program. In the present study, we identified several wheat-rye addition lines from the progeny of T. aestivum L. Mianyang11 × S. cereale L. Kustro, i.e., monosomic addition lines of the rye chromosomes 4R and 6R; a disomic addition line of 6R; and monotelosomic or ditelosomic addition lines of the long arms of rye chromosomes 4R (4 RL) and 6R (6 RL). All these lines displayed immunity to powdery mildew. Thus, we concluded that both the 4 RL and 6 RL arms of Kustro contain powdery mildew resistant genes. It is the first time to discover that 4 RL arm carries powdery mildew resistant gene. Additionally, wheat lines containing new wheat-rye translocation chromosomes were also obtained: these lines retained a short arm of wheat chromosome 5D (5 DS) on which rye chromosome 4R was fused through the short arm 4 RS (designated 5 DS-4 RS · 4 RL; 4 RL stands for the long arm of rye chromosome 4R); or they had an extra short arm of rye chromosome 4R (4 RS) that was attached to the short arm of wheat chromosome 5D (5 DS) (designated 4 RS-5 DS · 5 DL; 5 DL stands for the long arm of wheat chromosome 5D). These two translocation chromosomes could be transmitted to next generation stably, and the wheat lines containing 5 DS-4 RS · 4 RL chromosome also displayed immunity to powdery mildew. The materials obtained in this study can be used for wheat powdery mildew resistant breeding program.
