最近对几个模式植物基因组的生物信息学和遗传学分析表明，存在一组高度丰富的信号肽，被定义为富含半胱氨酸的多肽(CRP)。CRP的大小通常在50到90个氨基酸残基之间，它们是带正电荷的，它们含有4-16个半胱氨酸残基，这对正确的构象折叠是重要的。尽管CRP类之间存在结构差异，但每个类的成员在分子性质和功能上有着惊人的相似之处。本文综述了EPF/EPFL、SP11/SCR、PRSS、RALF、LORE等几个家族信号肽的最新研究进展，以及其他一些属于CRP类的信号肽。有令人信服的证据表明，这些CRP在植物生活史中作为信号分子发挥了多种作用，包括气孔发育和模式形成、自交不亲和、花粉管生长和引导、生殖过程和根瘤形成。
Recent bioinformatic and genetic analyses of several model plant genomes have revealed the existence of a highly abundant group of signaling peptides that are defined as cysteine-rich peptides (CRPs). CRPs are usually in size between 50 and 90 amino acid residues, they are positively charged, and they contain 4-16 cysteine residues that are important for the correct conformational folding. Despite the structural differences among CRP classes, members from each class have striking similarities in their molecular properties and function. The present review presents the recent progress in research on signaling peptides from several families including: EPF/EPFL, SP11/SCR, PrsS, RALF, LURE, and some other peptides belonging to CRP group. There is convincing evidence indicating multiple roles for these CRPs as signaling molecules during the plant life cycle, ranging from stomata development and patterning, self-incompatibility, pollen tube growth and guidance, reproductive processes, and nodule formation.
