	1	Phylogenetic Analysis on SLG and SRK Genes in Brassica and Raphanus显示文摘S-locus genes were cloned from three Brassica napus and three B. campestris lines by using PCR walking and homologuesequence methods. A phylogenetic gene tree was constructed based on the six cloned genes and fifty-one previouslyreported SLG/SRK genes of Brassica and Raphanus. The SLGs from R. sativus were dispersed in the phylogenetic treeintermingling with SLG/SRKs from B. oleracea, B. napus and B. campestris. The SLG/SRK genes of classⅡclusteredindependently in one group. The SLG/SRK genes of classⅠshowed to be more divergent than classⅡgenes. Theseresults suggested that the divergence of classⅠand classⅡ should have occurred before the differentiation of thegenera Brassica and Raphanus. In addition, SLG and SRK of the same S haplotypes belonged to the same class. Itsuggested that class-Ⅰ and class-Ⅱ group divergence occurred first, and then SLG and SRK diverged. The three SC SRKgenes from B. napus and B. campestris were grouped into one cluster, displaying difference from the SC SLG of B.oleracea. These three SC SRK genes were close to SI SRK of SI1300, SI271 and guanyou in phylogenetic relationships.These results indicated that SC and SI genes diverged more recently. It is not clear yet whether the differentiation of SCand SI genes was earlier than the differentiation of Brassica and Raphanus. Studies based on more genes are necessaryfor a comprehensive elucidation of the phylogenetic relationships in Brassicaceae.
