花卉体细胞胚胎发生研究进展

Studies of Flowers Somatic Embryogenesis

综述花卉体细胞胚胎发生途径、体细胞胚胎发生过程的生理生化变化及其影响因素、体细胞胚胎发生与胚性基因的表达和花卉体细胞无性系变异等方面的研究进展,植物体细胞胚胎发生研究在基因工程体细胞融合、细胞突变体诱导、人工种子、杂种合子胚的挽救、种质保存、苗木快速繁殖等诸多方面有着广阔的应用前景,也是遗传学、转基因工程体系、生理生化、植物发育过程的基因表达和调控、功能基因组研究等方面一个必不可少的新兴研究系统。

This paper summarizes the progress on the studies of the somatic embryogenesis,the changes of physiological and biochemical in the somatic embryogenesis,the relationship of somatic embryogenesis and embryogenic gene,and the clone variation in flower. The studied of somatic embryogenesis would be importance for somatic cell fusion, individual cell induction, artifiacal seeds production, hybrid zygote embryo saving, genetic resources preserving and in vitro multiplication and so on. It＇s also a new system for genetics, transgene, physiological and biochemical changes and the gene expression, gene expression regulation and the genome functions in the process of plant development study.
