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. Two sequences are identical between the majority of resistance gene candidate clones with a high similarity to Lrk10, and two sequences are identical between the majority of resistance gene candidate clones with similarity to the Cre3 gene.
