Outline of Final Research Achievements

Prunus (Rosaceae) exhibits the S-ribonuclease (S-RNase)-based gametophytic self-incompatibility (GSI), which hinders effective fruit production and breeding in Prunus fruit trees. This system is also present in the families Plantaginaceae and Solanaceae and the tribe Maleae of the family Rosaceae. The consequences of pollen S gene mutations and heterodiallelic pollen production differ between Prunus species and other plants, suggesting there are different pollen S functions during self/nonself-recognition. This study tested the working hypothesis that pollen expressed SLFLs located around the Prunus S locus region work as general inhibitor to detoxify all S-RNase. Results obtained have supported the working hypothesis but firm direct evidence has not been obtained.
