| 英文摘要 | P>the self-incompatibility (si) response occurs widely in flowering plants as a means of preventing self-fertilization. in these self/non-self discrimination systems, plant pistils reject self or genetically related pollen. in the solanaceae, plantaginaceae and rosaceae, pistil-secreted s-rnases enter the pollen tube and function as cytotoxins to specifically arrest self-pollen tube growth. recent studies have revealed that the s-locus f-box (slf) protein controls the pollen expression of si in these families. however, the precise role of slf remains largely unknown. here we report that phssk1 (petunia hybrida slf-interacting skp1-like1), an equivalent of ahssk1 of antirrhinum hispanicum, is expressed specifically in pollen and acts as an adaptor in an scf(skp1-cullin1-f-box)slf complex, indicating that this pollen-specific ssk1-slf interaction occurs in both petunia and antirrhinum, two species from the solanaceae and plantaginaceae, respectively. substantial reduction of phssk1 in pollen reduced cross-pollen compatibility (cpc) in the s-rnase-based si response, suggesting that the pollen s determinant contributes to inhibiting rather than protecting the s-rnase activity, at least in solanaceous plants. furthermore, our results provide an example that a specific skp1-like protein other than the known conserved ones can be recruited into a canonical scf complex as an adaptor. |
