plant-polyphenols

2 articles

Plant polyphenols are a diverse class of secondary metabolites synthesized by plants, characterized by multiple phenolic ring structures, and including compounds such as flavonoids, tannins, and stilbenes. They play critical roles in plant biology, serving as chemical defenses against pathogens and herbivores, UV protectants, and signaling molecules that mediate interactions with pollinators and soil microbes. Understanding their biosynthesis and regulation is central to plant science research, with implications for crop resilience, stress tolerance, and the breeding of nutritionally enhanced varieties.
