Regulatory networks of somatic embryogenesis in plant
植物体细胞胚胎发生的调控网络

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.
