Peptide signaling regulates a variety of developmental processes and environmental responses in plants. For example, the peptide systemin induces the systemic defense response in tomato and defensins are small cysteine-rich proteins that are involved in the innate immune system of plants. The CLAVATA3 peptide regulates meristem size and the SCR peptide is the pollen self-incompatibility recognition factor in the Brassicaceae. LURE peptides produced by synergid cells attract pollen tubes to the embryo sac. RALFs are a recently discovered family of plant peptides that play a role in plant cell growth.
肽信号调节植物的多种发育过程和环境响应。例如，肽系统素诱导番茄的全身防御反应，防御素是一种参与植物先天免疫系统的富含半胱氨酸的小蛋白。CLAVATA3 肽调节分生组织的大小，SCR 肽是十字花科植物花粉自交不亲和识别因子。由助细胞产生的 LURE 肽吸引花粉管进入胚囊。RALFs 是最近发现的一类植物肽，在植物细胞生长中发挥作用。
