Frequent loss of lineages and deficient duplications accounted for low copy number of disease resistance genes in Cucurbitaceae.

BMC genomics - 17 May 2013

Abstract excerpt

BACKGROUND: The sequenced genomes of cucumber, melon and watermelon have relatively few R-genes, with 70, 75 and 55 copies only, respectively. The mechanism for low copy number of R-genes in Cucurbitaceae genomes remains unknown. RESULTS: Manual annotation of R-genes in the sequenced genomes of Cucurbitaceae species showed that approximately half of them are pseudogenes. Comparative analysis of R-genes showed...
