摘要: 高等植物的第一个多肽激素(系统素)发现已经有10多年的历史。到目前为止, 被普遍认可的植物多肽激素有4种: 系统素、PSK、CLV3和SCR, 分别参与了植物的防御反应、细胞的分裂、茎端生长点干细胞数目维持和花粉-柱头的识别过程。这些小分子多肽化合物以配基的形式与细胞膜表面的受体激酶相互作用, 从而实现细胞之间的信号交流。本文对这4种多肽激素及其相应受体的研究进展做了简要评述, 并着重介绍当前研究比较热门的CLV3多肽, 最后对相关领域的发展前景进行探讨。

Abstract: Although the first peptide hormone (systemin) in plants has been discovered for more than ten years, till now only four peptides have been accepted as peptide hormones. They are systemin, PSK, CLV3 and SCR, involved in wounding response, cell division, stem cell maintenance in the shoot apical meristem, and the interaction between pollen and stigma, respectively. These small peptides act as ligands to interact with receptor kinases located on the surface of the cytoplasma membrane, triggering downstream signal transductions.In this paper we outline the progresses made in this area, with emphasis on CLV3 peptides. We also provide our prospective vision in this field.
