Abstract:
Involvement of the S^e-haplotype in self-compatibility in the Japanese plum cultivars ´Santa Rosa` (S<sup>c</sup>S<sup>e</sup>) and ´Beauty` ( S^cS^e), was investigated. Self-pollination and pollen-tube growth tests confirmed that cv. ´Rio`, which also has a S^e haplotype ( S^aS^e), is self-compatible. In self- and cross-pollination experiments between cultivars with the S^cS^e haplotype, the resultant progenies segregated into two S-haplotypes, S^cS^e and S^eS^e, suggesting that only the S^e-haplotype was inherited in progeny from the male parent. These results indicated that the S^e-haplotype is responsible for self-compatibility. Expression analyses of S-RNase showed that the S^e-RNase gene was transcribed in the style. Therefore, it appeared that inhibition of transcription of the S-RNase gene is not responsible for the self-compatibility in the S^e-haplotype of Japanese plum.
