Research Progress on Light-regulated Synthesis of Plant Polyphenols
Plant polyphenols are a complex class of phenolic secondary metabolites with polyphenol structure in the plants,which can cope with oxidative damage caused by biotic and abiotic stresses.Therefore plant polyphenols play important roles in plant growth and development.Light has a crucial impact on plant growth and development and polyphenol synthesis,which mainly affects the synthesis of polyphenols by regulating metabolic pathway genes such as phenylpropanoid pathway.The paper briefly described the synthesis pathway of polyphenols,and summarized the effects of light on thesynthesis of polyphenols from three aspects:photoperiod,light intensity and light quality,aiming to provide theoretical basis for future research on the regula-tory mechanisms of polyphenol production.
