Analysis of the style-specific, self-compatible haplotype S4sm. (A) A cosmid contig for the S4 haplotype and DNA gel blot analysis with cosmid-derived probes. Open boxes denote cosmid clones. N, Nijisseiki (S2S4); O, Osa-Nijisseiki (S2S4sm); K, Kosui (S4S5); C, Chojuro (S2S3); H, Hayatama (S1S2). (B) PCR amplification of SFBB genes from genomic DNA of Nijisseiki and cosmid clones for the S4 haplotype. (C) CAPS analysis of the S4smS4sm genotype, Chukanbohon Nou No.1, and other S genotypes.
