摘要:

苹果、梨等果树均具有典型的配子体型自交不亲和性,该性状是由单一位点(S-locus)上的分别控制花柱和花粉特异性的复等位基因(S-allele)所决定的。其中,控制花柱自交不亲和性的决定因子被确定为S-RNase,而花粉决定因子则可能是由SLFS-locus F-box)/SFBS-haplotype-specific F-box)控制。以蔷薇科果树和芸香科果树为例,从自交不亲和反应雌、雄决定子的发现、自交亲和突变机制研究、S-RNase介导的花粉管信号转导,以及自交亲和种质在果树育种中的应用等方面综述果树自交不亲和机制研究进展,以期为后续自交不亲和性研究提供一定参考。

Abstract:

Self-incompatibility is a genetic mechanism which inhibits self-crossing and promotes out-crossing in flowering plants. Apple,pear,and other fruit trees exhibit the typical gametophytic self-incompatibility that is determined by the multiple alleles(S-allele)at a single locus(S-locus)containing at least two genes. One is the stylar-S determinant that is determined by the S-RNase gene,while the other is the pollen-S determinant that may be controlled by one or multiple F-box genes. The research progress of gametophytic self-incompatibility in Rosaceae and Rutaceae fruit trees is introduced as follows:the discovery of the male and female determinants,the mechanism of self-incompatibility mutation,S-RNase-mediated pollen tube signal transduction,and the application of self-incompatibility mutation in new variety breeding. These information is available for the studies of gametophytic self-incompatibility in future.

Key words: fruit tree, gametophytic self-incompatibility, S-RNase, pollen F-box
