Abstract
Self-incompatibility in Brassica species is regulated by a set of S-locus g enes: SLG, SRK, and SP11/SCR. In the vicinity of the S-locus genes, several expressed genes, SLL2 and SP2/ClpP, etc., were identified in B. campestris . Arabidopsis thaliana is a self-compatible Brassica relative, and its comp lete genome has been sequenced. From comparison of the genomic sequences be tween B. campestris and A. thaliana, microsynteny between gene clusters of Arabidopsis and Brassica SLL2 regions was observed, though the S-locus gene s, SLG, SRK, and SP11/SCR were not found in the region of Arabidopsis. Almo st all genes predicted in this region of Arabidopsis were expressed in both vegetative and reproductive organs, suggesting that the genes in the SLL2 region might not be related to self-incompatibility. Considering the recent speculation that the S-locus genes were translocated as a single unit betw een Arabidopsis and Brassica, the translocation might have occurred in the region between the SLL2 and SP7 genes.
