Sources and Discovery of Plant Peptides

The origins of peptides in plants are primarily endogenous, with plants synthesizing them from their own protein precursors. Bioactive peptides are mainly produced from plant proteins through enzymatic cleavage. This process allows plants to generate a diverse repertoire of signaling molecules from a limited number of larger proteins.

The scientific community is increasingly recognizing the potential of these natural compounds. Databases like PlantPepDB are being developed to catalogue the growing number of identified plant peptides, facilitating further research. Advanced computational methods, such as AI-driven pipelines, are also being employed to discover hidden signaling peptides in plants, revealing new families of molecules and their functions.
