植物体细胞胚胎发生受体类蛋白激酶的生物学功能

体细胞胚胎发生受体类蛋白激酶(Somatic embryogenesis receptor-like kinases,SERKs)属于膜富亮氨酸重复序列受体类蛋白激酶(Leucine-rich repeat sequence receptor-like kinase,LRR-RLK)家族的第二亚类。SERK具有典型的胞外信号受体结构域、跨膜结构域和胞内激酶活性结构域,研究发现SERKs在植物生命活动中承担着多个角色。文章简述了SERKs的典型结构域特征,重点介绍该类蛋白在体细胞胚发生、生殖发育、激素感应和病理反应方面发挥的功能,同时对该蛋白激酶的研究价值和应用前景进行了探讨。

Biological function of the Somatic embryogenesis receptor-like kinases in plant

Somatic Embryogenesis Receptor-Like Kinases (SERKs) belong to the LRR-RLK II subfamily, which contain three conserved domains: an extracellular domain, a transmembrane domain, and an intracellular catalytic kinase domain. Previous studies had found that SERKs play many roles during plant development. This review made a brief introduction about the character of the SERKs and described the biological function of these proteins in somatic embryogenesis, sporogenesis, hormone response and host defense response. The research value and the application prospects of the SERKs were discussed.
