| Outline of Final Research Achievements |
Mechanism of the pollen S gene expression in flowering plants are difficult to interpret, because of the complex physiological phenomena that occur in the stigma and the style tissue. In this study, we examine about the non-self or self-recognition system using the mature pollen culture in self-incompatibility(SI) of citrus. As a result of investigating the multiple microsatellite (SSR) genotyping of a single pollen grain, for analyzing the element of pollen S gene and its segregation, it was revealed that seven of the 8 segregating loci in the pollen population of ‘Banpeiyu’ pummelo(Citrus maxima (Burm.)Merr.) fit a 1: 1 ratio. In addition, the results of inhibition rate of pollen tube using the mature pollen culture were showed the possibility having non-self recognition by multiple factors SI system.
