Different gene order of SRKs relative to SLGs in Brassica class-I and class-II S haplotypes. The gene order of SRKs and SLGs from two class-II S haplotype (B. rapa S-60 and B. oleracea S-15) and 4 class-I haplotypes (B. rapa S-9 and S-46; Bnn napus S-A14 and S-910) is compared. The arrangement of the S loci was determined by molecular markers in the S-locus flanking region 1 and region 2 (modified from ).
