| Research Abstract |
Prunus in the Rosaceae show the gametophytic self-incompatibility system, which hinders effective fruit production and breeding in Prunus. This study was started to elucidate the molecular basis of the gametophytic self-incompatibility in Prunus. We identified pollen expressed actin that binds to the pistil Sdeterminant, S-RNase. Furthermore, we identified a Skp1-like protein called SSK1 that binds to the pollen Sdeterminant, SFB. We have cloned Cul1 that forms the SCF complex with SSK1 and SFB. Based on the results obtained, we have developed the working hypothesis for the molecular recognition of the gametophytic self-incompatibility in Prunus.
