摘　要：

类受体蛋白(receptor-like protein, RLP)广泛存在于高等植物中, 其家族在拟南芥中有57个成员。研究表明RLP蛋白参 与了植物茎尖分生组织(shoot apical meristem, SAM)、根尖分生组织(root apical meristem, RAM)和维管分生组织等器官的 生长与发育过程, 例如CLV2 (CLAVATA2)和FEA2 (FASCINATED EAR2)参与了分生组织的维持与分化和其他器官的发 育、TMM (TOO MANY MOUTHS)则介导了植物表皮细胞的分裂和气孔分布。另一方面, RLP蛋白在植物抗病中发挥着 重要作用, 包括番茄抗叶霉菌Cf类蛋白、番茄抗黑白轮枝菌Ve1和Ve2以及番茄应答非致病绿色木霉菌激发子的抗病蛋白 LeEix等。同时, 研究表明RLP蛋白在细胞间信号的接受与传递过程中起着极为重要的作用。本文综述了近年来对植物类 受体蛋白参与植物生长与发育的功能、信号识别、传输与转导等方面的研究进展。

Abstract:

Receptor-like proteins (RLPs) are present in many plant species with a total of 57 members in Arabidopsis thaliana. It was shown that RLP proteins are implicated in plant growth and development as well as in disease resistance. CLAVATA2 (CLV2), FASCINATED EAR2 (FEA2) and TOO MANY MOUTHS (TMM) play a role in plant development; CLV2 and its functional maize ortholog FEA2 regulates meristem maintenance and organogensis, while TMM regulates stomatal distribution. In addition, RLPs have been found to play a role in disease resistance, such as the tomato (Solanum lycopersicum) Cf, Ve and LeEix proteins that mediate resistance against the fungal pathogens Cladosporium fulvum, Verticillium spp., and Trichoderma viride, respectively. Evidence is also accumulating for RLP to be a critical component in cell-to-cell communication. The progress of RLP functioning and signaling are summarized in this review.

Key words: receptor-like protein; Arabidopsis; growth and development; signal transduction
