| 英文摘要 | Self-incompatibility (si), an important barrier to inbreeding in flowering plants, is controlled in many species by a single polymorphic s-locus. in the solanaceae, two tightly linked s-locus genes, s-rnase and slf (s-locus f-box)/sfb (s-haplotype-specific f-box), control si expression in pistil and pollen, respectively. the pollen s-determinant appears to function to inhibit all but self s-rnase in the solanaceae, but its genetic function in the closely-related plantaginaceae remains equivocal. we have employed transposon mutagenesis in a member of the plantaginaceae (antirrhinum) to generate a pollen-part si-breakdown mutant pma1 (pollen-part mutation in antirrhinum1). molecular genetic analyses showed that an extra telocentric chromosome containing ahslf-s (1) is present in its self-compatible but not in its si progeny. furthermore, analysis of the effects of selection revealed positive selection acting on both slfs and sfbs, but with a stronger purifying selection on slfs. taken together, our results suggest an inhibitor role of the pollen s in the plantaginaceae (as represented by antirrhinum), similar to that found in the solanaceae. the implication of these findings is discussed in the context of s-locus evolution in flowering plants. |
