Small peptides (SPs), ranging from 5 to 100 amino acids, play integral roles in plants due to their diverse functions. Despite their low abundance and small molecular weight, SPs intricately regulate critical aspects of plant life, including cell division, growth, differentiation, flowering, fruiting, maturation, and stress responses. As vital mediators of intercellular signaling, SPs have garnered significant attention in plant biology research. This comprehensive review delves into SPs' structure, classification, and identification, providing a detailed understanding of their significance. Additionally, we summarize recent findings on the biological functions and signaling pathways of prominent SPs that regulate plant growth and development. This review also offers a perspective on future research directions in peptide signaling pathways.
小肽（SPs），由 5 到 100 个氨基酸组成，由于其多种功能，在植物中起着重要作用。尽管它们的丰度低，分子量小，但 SPs 却错综复杂地调节着植物生命的关键方面，包括细胞分裂、生长、分化、开花、结果、成熟和应激反应。作为细胞间信号传导的重要介质，SPs 在植物生物学研究中受到了广泛关注。本综述深入探讨了 SPs 的结构、分类和鉴定，详细了解了它们的重要性。此外，我们总结了最近关于调节植物生长和发育的主要 SPs 的生物学功能和信号通路的发现。本综述还对肽信号通路的未来研究方向提供了一个视角。
