摘　　要：植物小孢子胚胎发生是作物遗传育种研究中的一个重要内容,也可以用来作为一个研究离体胚胎发育的优良模式系统。小孢子胚胎发生可以分为获得胚性潜能、启动细胞分裂和图式形成等3个特征阶段,对这3个阶段中主要的细胞分子特征进行综述。Microspore embryogenesis has been representing an important tool for research in plant genetics and breeding. From a developmental point of view, microspore embryogenesis is a rewarding system for understanding the process of embryo formation from single, haploid microspores. Microspore embryogenic development can be divided into three main characteristic phases including acqui- sition of embryogenic potential, initiation of cell divisions, and pattern formation. The aim of this review was to provide an overview of the main cellular and molecular events that characterize these three commitment phases.
