Abstract excerpt
BACKGROUND: The Pi2/9 locus contains multiple nucleotide binding site-leucine-rich repeat (NBS-LRR) genes in the rice genome. Although three functional R-genes have been cloned from this locus, little is known about the origin and evolutionary history of these genes. Herein, an extensive genome-wide survey of Pi2/9 homologs in rice, sorghum, Brachypodium and Arabidopsis, was conducted to explore this theme....
