Abstract:

Flavonoids are a class of secondary metabolites with ‘flavan’ skeleton and thousands of derivatives. The biosynthetic pathways of flavonoids are complicated,and some of them and related enzymes have been analyzed. Flavonoids play important roles in the growth and development of plants and the formation of flowers and fruits. Studies revealed that flavonoids can response to stresses and improve the tolerance and resistance of plants. This article reviews the biosynthetic pathways and molecular regulation mechanism of flavonoids in plants,the response of flavonoid pathways to different stresses,the main roles and mechanisms of flavonoids,and the future research directions. Thus,this article is expected to providing theoretical support for the targeted cultivation of horticultural crop varieties with highly resistant,deep processing,and product development.

Key words: flavonoids, biosynthesis, regulation, stress, role and mechanism
