Plant peptides are small chains of amino acids that play a fundamental and diverse role in virtually every aspect of plant life, acting as crucial signaling moleculesPeptides in plant reproduction—small yet powerful. Far from being mere building blocks, these peptides are essential regulators of plant growth and development, orchestrate complex defense mechanisms against pathogens, and enable plants to adapt to environmental stresses. While the broader category of peptides encompasses many compounds, understanding plant peptides specifically reveals a sophisticated communication network within plants, vital for their survival and propagation. Research into plant peptides has significantly expanded, uncovering their intricate functions and potential applications.

Plant peptides are critical in mediating these stress responses.作者：X Chen·2025·被引用次数：24—Here, we discovered aplant-derived noncanonical antibacterialpeptide(NCBP1) against both Gram-positive and Gram-negative bacteria. They can trigger defense pathways, enhance tolerance to abiotic stresses like salt, and bolster the plant's immune system against infections. This includes the action of plant antimicrobial peptides (AMPs) which directly combat pathogens.
* Defense Mechanisms: Beyond general stress, specific plant peptides are directly involved in defense against pathogen infection. These can act as signaling molecules that alert the plant to an invasion, or as direct effectors that fight off bacteria, fungi, and viruses. Families such as defensins, lipid transfer proteins (LTPs), thionins, heveins, and cyclotides are notable examples of plant defense peptides.
Plant peptides function primarily through signaling pathways. They bind to specific receptors on cell surfaces, initiating a cascade of events within the cell that leads to a specific biological response. This peptide signaling is analogous to hormone signaling in animals, allowing for precise control over cellular activities.
