摘　　要：小孢子是高等植物生活史中雄配子体发育过程中短暂而重要的阶段,是减数分裂后四分体释放出的单核细胞。现从细胞学和分子机制两方面对近年来有关蔬菜作物小孢子胚胎发生诱导中小孢子细胞形态的变化、生化改变和细胞质的模型再建、细胞核重排、分裂途径、多细胞花粉胚的发育和蔬菜作物小孢子胚胎发生的分子机制,如胚胎发生相关基因的克隆和表达、胚胎发生相关蛋白等研究进行了综述及展望,旨在为进一步研究小孢子胚胎发生机理提供理论依据和奠定技术基础。Microspore is a short and important stage in the male gametophyte development process of higher plants life history,and it is monocyte released by tetrad in meiosis stage. From the aspects of cytology and molecular mechanisms of microspore in recent years, tile microspore embryogenesis of cell morphology changes, biochemical changes, cytoplasmic model rebuilding, nuclear rearrangements, split ways,multi-cellular pollen embryos and microspore molecular mechanisms of cloning and expression of embryonic related genes and proteins of vegetables were summarized and prospected,in order to provide a theoretical basis and technological foundation for further research on microspore embryogenesis mechanism.
