“…Molecular markers have not only been successfully employed in determining the location of Triticum aestivum-and T. dicoccoides-derived powdery mildew resistance loci at the subchromosomal level (Hartl et al 1995(Hartl et al , 1999Huang et al 2000b;Rong et al 2000;Tao et al 2000;Liu et al 2002;Neu et al 2002), but they have also been instrumental in the genetical delimitation of alien translocation fragments harbouring powdery mildew resistance determinants: Pm13 from Aegilops longissima was mapped to a translocated3S l S segment distal to Xcdo460-3B (Cenci et al 1999), and Pm27 from T. timopheevii was pinpointed to a fragment with breakpoints between the marker loci Xpsr8/Xpsr964 on 6BS and Xpsr154/Xpsr546 on 6BL (Järve et al 2000).…”

The powdery mildew resistance gene Pm22, identified in the Italian wheat cultivar Virest and originally assigned to wheat chromosome 1D, was mapped to chromosome 7A with the aid of molecular markers. Mapping of common AFLP and SSR markers in two wheat crosses segregating for Pm22 and Pm1c, respectively, indicated that Pm22 is a member of the complex Pm1 locus. Pm22 also showed a pattern of resistance reaction to a differential set of Blumeria graminis f. sp. tritici isolates that was distinguishable from those from other Pm1 alleles in lines Axminster/8*Cc ( Pm1a), MocZlatka ( Pm1b), Weihenstephan Stamm M1N ( Pm1c) and Triticum spelta var. duhamelianum TRI 2258 ( Pm1d). Based on these results, the gene symbol Pm1e is proposed for the powdery mildew resistance gene in cv. Virest.

“…They have been widely used in wheat for gene mapping. Currently, SSR markers have been successfully used in important wheat traits such as resistance to stripe rust and powdery mildew resistance gene mapping research (Jarve et al 2000;Liu et al 2002). In our laboratory, many leaf rust resistance genes such as LrZH84 (Zhao et al 2008), LrG98 (Chen et al 2010), LrXi (Li et al 2010a), LrBi16 (Zhang et al 2011), LrNJ97 (Zhou et al 2013), and LrFun (Xing et al 2014) were identified using SSR markers.…”

Qi A., Li X., Shi L., Liu D., Li Z. (2015): Identification of a leaf rust resistance gene in the Chinese wheat line LB0288. Czech J. Genet. Plant Breed., 51: 43-49.Leaf rust (LR), caused by Puccinia triticina (Pt), is worldwide one of the most spread diseases in common wheat (Triticum aestivum L.). With the objective of identifying and mapping new genes for resistance to leaf rust, F 1 and F 2 plants from a cross between the resistant cultivar LB0288 and the susceptible cultivar Thatcher were inoculated with the Chinese P. triticina pathotype THTT in the greenhouse. A set of 1273 simple sequence repeat (SSR) primer pairs were used to test the parents and the resistant and susceptible bulks. The results indicated, that LB0288 carried a single dominant resistance gene LrLB88, closely linked to the CAPS marker of Lr1 (WR003) and the SSR marker Xbarc144, with genetic distances of 0 cM and 5.3 cM, respectively. Based on the chromosomal location and seedling reactions, it can be concluded that LrLB88 might be a new leaf rust resistance gene. These markers can be useful for marker assisted selection in breeding of leaf rust resistant wheat cultivars.

“…Using RFLP and microsatellite analysis, a Triticum timopheevii translocation was detected in chromosome 6B of the hybrid line 146-155-T and its breakpoints were located (Järve et al, 2000). The results of the hybridization of the rDNA intergenic spacer fragment showed that the region flanking the NorB2 locus in the introgression line originated from chromosome 6G of T. timopheevii and had been transferred into 146-155-T by homoeologous recombination.…”

Timopheevii wheats are discussed as donors for improving the disease resistance of common wheat. Attention is paid to the comparison of the morphological and chromosomal characteristics of Triticum timopheevii and T. militinae, their crossability with T. aestivum and their response to fungal diseases. The possible origin of T. militinae from an introgressive hybridization between T. timopheevii and an unknown species is discussed. Major genes for resistance to various fungal diseases, transferred to common wheat from T. timopheevii, are listed.
