摘要:

体细胞胚胎发生作为细胞全能性的一种表达方式,不仅在植物的遗传改良和产业化快速繁殖等方面有着重大实践意义,也是开展植物发育生物学理论研究的理想模型。综述多胺和乙烯在植物体胚发生过程中的作用及其分子作用机制的研究进展,主要涉及多胺和乙烯的合成分解代谢过程、体细胞胚胎发育在相关基因和蛋白质组学等方面的研究进展,为进一步深入了解体细胞胚的发生发育规律及基因调控机制以及建立植物高效再生体系提供参考。

关键词: 体细胞胚胎发生, 多胺, 乙烯

Abstract:

Somatic embryogenesis is an expression mode of totipotency, it not only has important practical uses in genetic improvements and industrializing propagation, but also is an ideal research model for studying plant developmental biology. This paper reviewed progress of study on roles of polyamines and ethylene during plant somatic embryogenesis, the molecular mechanism mainly related to the biosynthesis catabolism of polyamines and ethylene, and somatic embryogenesis in the gene and proteomics research. The review could provide reference for further understanding the developmental patterns and gene regulation mechanism of somatic embryogenesis and for establishing efficient plant regeneration system.

Key words: somatic embryogenesis, polyamine, ethylene
