摘　要：

核糖体由核糖体RNA和核糖体蛋白组成。植物核糖体的组成蛋白共81种, 每种都包含2~7个序列不同的成员。不同成员形成的组合使得核糖体具有了高度的组织特异性, 这是植物核糖体区别于其他真核生物的重要特征, 也被认为是植物适应固着生长和环境变化的方式之一。因此, 植物核糖体蛋白可能参与了植物特定时期的生长发育过程, 有些还可能演化出核糖体外的功能。本文综述了拟南芥核糖体蛋白参与的植物发育及响应胁迫应答的研究进展。

Abstract:

Arabidopsis thaliana genome encodes 81 different types of ribosomal proteins. Each ribosomal protein is encoded by two to seven expressed genes paralogs, forming a family, which could contribute to ribosome high heterogeneity in plant. The heterogeneity of plant ribosome is an important characteristic of plant ribosome distinguished from other eukaryotes, and regarded as attributable to the sessile nature of plants and adaptable under changing environments. Ribosomal proteins are involved in plant growth and developmental process, and some of the paralogs might evolve extraribosomal functions. This paper summarizes the research progress of ribosomal protein function of involving development and response to stress in A. thaliana.

Key words: ribosome; ribosomal proteins; Arabidopsis thaliana
