At their core, plant peptides are short chains of amino acids, a fundamental component of proteins. However, their significance lies in their specific sequences and structures, which dictate their unique biological activities. Research highlights that plants are prolific peptide chemists, producing thousands of different peptidic molecules, each with potentially distinct functions. These molecules are often generated through proteolytic cleavage, a process where larger proteins are broken down into smaller, active peptides. This is a fundamental aspect of plant-derived bioactive peptide production, with methods like enzyme hydrolysis playing a crucial role in their extraction and isolation.

One of the most well-documented roles of plant peptides is in plant defense作者：YL Chen·2020·被引用次数：128—Plant peptides have recently emerged as key signaling molecules of stress responses, not only to mechanical wounding and pathogen infection but .... They are constituent molecules of the innate defense system, acting as a first line of response against threats. Plant peptides involved in defense against pathogen infection are crucial for plant survival, triggering immune responses and protecting against microbial invaders. Studies have identified specific plant-derived noncanonical antibacterial peptide (NCBP1) with efficacy against both Gram-positive and Gram-negative bacteria, showcasing their potential as natural antimicrobials. Furthermore, defense peptides are part of plants' innate immune system and show widespread occurrence across the plant kingdom, underscoring their evolutionary importancePlant peptides – taking them to the next level - Oxford Academic.

Beyond defense, plant peptides are deeply involved in regulating plant growth, development, reproduction and environmental stress responses. They are currently being considered as a novel class of plant hormones, acting as signaling molecules that orchestrate complex physiological processes. Peptide signaling plays a significant role in various aspects of plant growth and development, with specific receptors identified for various peptides.
