Suppression of gene expression of a recessive SP11/SCR allele by an untranscribed SP11/SCR allele in Brassica self-incompatibility.

Abstract excerpt

Mutations in the S locus of a self-compatible cultivar Yellow Sarson in Brassica rapa, which has a self-compatible class-I S haplotype, S-f2, were investigated. S-28 in Brassica oleracea was found to be a member of an interspecific pair with S-f2 in B. rapa. The original S haplotype of S-f2 was identified to be S-54 in B. rapa. Sequence comparison of alleles in S-f2 with those in S-54 and B. oleracea S-28...
