Application of STS markers for leaf rust resistance genes in near-isogenic lines of spring wheat cv. Thatcher.

Sequence tagged site (STS) markers for eight resistance genes against Puccinia recondita f. sp. tritici were used to screen a set of near-isogenic lines of wheat cv.

Leaf rust resistance genes of wheat: identification in cultivars and resistance sources.

Thirty-seven wheat cultivars originating from seven European countries were examined by using sequence tagged site (STS) markers for seven Lr (leaf rust = brown rust) resistance genes against the fungal pathogen of wheat Puccinia recondita f. sp. tritici (Lr9, Lr10, Lr19, Lr24, Lr26 and Lr37).

Putative resistance genes of cereals: structure and expected function.

Sequences of two recently cloned genes playing a role in resistance against wheat pathogens (receptor-like kinase Lrk10 and Cre3 genes) were used to search for similarity of cereal clones included in the NCBI database. We found 23 clones with similarity to the Cre3 gene with predicted NBS and LRR domains, and 50 clones with serine/threonine kinase function and similarity to the new receptor-like kinase gene Lrk10 from wheat. In those two groups of clones some conservative nucleotide sequences were identified.
