摘要: 植物在调控生长发育、响应外界胁迫时, 细胞内外的pH 变化是及时、重要的反应之一。快速碱化因子类基因( RALF) 属于植物多肽类信号分子, 是一类大的家族基因, 它的活动引起胞外pH 值快速升高, 有关RALF 类基因的研究在几种茄科植物中开展的较多, 包括RALF 蛋白信号分子的结构及加工、基因表达、受体研究以及功能等方面。最近我们在白菜和紫菜薹中的研究发现有一些RALF 类基因与植物的育性有关, 本文就茄科植物中的这些研究进展进行介绍, 为RALF 的进一步研究提供参考。

关键词: 快速碱化因子, RALF, 茄科植物

Abstract: The change of the intra- and extra-cellular pH played important roles in plant growth and development and response to environmental stresses . Rapid alkalinization factors ( RALF) were polypeptide signals in the plant , belonging to a large gene family . The activity of RALF could induce extra-cellular pH increasing rapidly .Many studies on RALFs were in Solanum, including the structure and maturation , the gene expression , receptors and functions and so on. Combining our recent findings on the rdationship between RALF and fertility in plants, the present paper introduced the process of the research
on the RALF in Solanum and provided references for the further studies in this orea .

Key words: Rapid alkalization factor
