Control of S-RNase-based self-incompatibility
<正>Self-incompatibility(SI)is an intraspecific reproductive barrier in flowering plants to prevent self- fertilization.In this self/non-self discrimination system,plant pistils reject self or genetically related pollen.In the most widespread SI system,pistil-secreted S-RNases enter pollen tube and function as cytotoxins to specifically inhibit growth of the cognate pollen tube.However,how this inhibition occurs is unclear.Recently, the S-locus F-box(SLF)protein has been demonstrated to be the pollen determinant,but its precise role remains largely unknown.We provide evidence showing that SLF-interacting SKP1-like1(SSK1)protein is
