植物体细胞胚胎发生的调控网络

Regulatory networks of somatic embryogenesis in plant

摘要:

植物体细胞胚胎发生是一个极其复杂而有序的过程，受到多种内、外因素的影响与调控。其中基因的表达与调控是影响体细胞胚胎发生最重要和最根本的因素。这些基因包括PLANT GROWTH ACTIVATOR系列基因、LEAFY COTYLEDON家族基因、BABY BOOM基因、SOMATIC EMBRYOGENESIS RECEPTOR-LIKE KINASE基因和PICKLE基因等，它们相互作用构成了一个复杂的调控网络。以下结合本实验室对PLANT GROWTH ACTIVATOR 37等基因的研究，对这一调控网络进行了介绍，并探讨了未来体细胞胚胎发生的研究方向。

Abstract:

The somatic embryogenesis in plant is a very complicated and highly ordered process, which is regulated by many internal and external factors. Among them, gene expression and regulation are key factors. Genes encoding regulatory proteins, for example PLANT GROWTH ACTIVATOR, LEAFY COTYLEDON, BABY BOOM, SOMATIC EMBRYOGENESIS RECEPTOR-LIKE KINASE and PICKLE, interact with each other and form a complicated regulatory network. Recent progress on this regulatory network was reviewed on the basis of our study on the PLANT GROWTH ACTIVATOR 37 gene. In addition, future research perspectives on plant somatic embryogenesis were discussed.
