植物多肽激素研究概况

Peptide Hormones in Plants

目前发现的植物多肽多达9种。基于配基-受体的胞间互作模式,目前公认的植物多肽激素包括4种:系统素(Systemin)、植物硫肽激素(Phytosulfokine)、SCR/SP11和CLV3,分别参与了植食性昆虫防御反应、细胞增殖、自交不亲和的识别,以及茎分生组织干细胞分裂与分化平衡的维持。本文对四种植物多肽激素基因家族的研究进展做了较为详尽的综述,并结合本试验室的研究进展做了展望。

There are at least nine members in the plant peptides, whose protein sequences have been published. Basing on the cell-to-cell interaction＇s pattern of ＂ligand-receptor＂, four peptides have been accepted as peptide hormones, including Systemin, Phytosulfokine, SCR/SP11 and CLV3, which are involved in wounding respond, cell proliferation, percipience between pollen and stigma in self-incompatibility, and balancing division and differentiation in the shoot apical meristem （SAM）, respectively. Here, we outline recent understanding of these four plant peptide hormones, meanwhile make a prospection according to our research＇s advance.
