Abstract:

Pollen-pistil interaction plays an important role in evolutionary process of species by influencing pollen affinity and serving as reproductive barriers,which determines the reproductive mode of higher plants. Therefore,on the one hand,cloning of male or female recognition factors is the basis of in-depth understanding of plant reproduction mode,which is of great significance for the analysis of the evolutionary mechanism of species. On the other hand,for crop breeding practices that rely extensively on selfing or hybridization,in-depth analysis of the function and mechanism of male or female recognition factors is also of great breeding value. In this review,the current research progress of pollen-pistil interaction factors were summarized systematically,especially in Arabidopsis thaliana,tomato,torenia and other model crops for pollen-pistil recognition research. The structure of pollen and pollen tube,and the S-locus,which determines self-incompatibility,are firstly introduced. Then,according to the sequence of pollen tube extension on female organs,stigma,style and ovule were introduced,and the correlation and uncorrelation between self-incompatibility and cross-incompatibility were introduced in detail. Finally,the research focus of pollen-pistil interaction was prospected.

Key words: sexual reproduction, self-incompatibility, unilateral incompatibility, cross-incompatibility, incongruity, pollen-pistil interactions
