摘要

The study of plant peptides has gained significant attention in recent years, emerging as a crucial area of research with broad implications in agriculture, pharmaceuticals, and nutraceuticals. These short chains of amino acids serve diverse functions, including plant growth regulation, stress tolerance, and pest protection, and offer advantages like high specificity, low toxicity, membrane permeability, low immunogenicity, and biodegradability. This review provides a comprehensive overview of plant peptides, including their characteristics, genetic origin, classification, production methods, and mechanisms of action. Various types of peptides, such as cyclotides, orbitides, PawS-derived peptides, cysteine-rich peptides, etc. are thoroughly discussed. These peptides possess antimicrobial, antifungal, and cytotoxic properties, contributing significantly to plant immunity. The review also highlights peptides involved in helping plants adapt to environmental stresses like drought, cold, salinity, etc. Additionally, hormone-like peptides, such as CLAVATA3/Embryo surrounding region, C-terminally Encoded Peptide, Phytosulfokine, Rapid Alkalinization Factor, etc. are explored for their roles in regulating plant physiological processes like cell division, differentiation, and growth. Understanding the molecular mechanisms and functions of existing plant peptides is crucial for identifying and developing new peptides. This knowledge opens up opportunities for creating innovative products like bio-based pesticides, biostimulants to boost crop resilience, and nutraceuticals that offer health benefits. The review highlights importance of plant peptides in advancing agriculture and biotechnology, presenting opportunities for improving crop productivity and sustainability.
