Abstract
The deduced peptide sequences of 25 gene fragments of NBS-LRR resistance (R) gene homologues from rice and barley and of characterized R genes were compared, revealing a string of six conserved motifs. Mapping of the R-gene candidates in rice showed linkage to genes conferring race-specific resistance to rice blast (Pi-k, Pi-f and Pi-1) and bacterial blight disease (Xa-1, Xa-3 and Xa-4), in barley to powdery mildew (Mla) and the rust fungus (Rpg1). In rice four mixed clusters were detected, each harboring at least two highly dissimilar NBS-LRR genes. A YAC-contig was established for one of these mixed clusters. YAC fragmentation experiments revealed the presence of at least five NBS-LRR genes within 200 kb in head-to-tail orientation.
