Abstract

The nucleotide (nt) sequences of the 5'-flanking regions of two Brassica self-incompatibility genes, SLG⁹ and SRK⁹, were determined. Their sequences were highly conserved: a region spanning 1.9 kb in the 5'-flanking region was completely identical except for a 1319-bp segment in SLG⁹. These observations strongly suggest that SLG⁹ and SRK⁹ together with their promoter regions were involved in a gene duplication or conversion event which occurred before the 1319-bp SLG⁹-specific sequence was inserted in SLG⁹ or deleted in SRK⁹.
