类黄酮化合物在植物胁迫反应中作用的研究进展

Advances in the Research on Flavonoid Biosynthesis and Plant Stress Response

植物胁迫发生时,一个明显的特征是在植物器官中积累红色与紫色类黄酮化合物。文章讨论了类黄酮化合物在植物胁迫保护中作用,如类黄酮化合物在抗植物UV-B辐射、抗病性以及铝毒害耐性等多方面的作用,也讨论了植物受胁迫时类黄酮积累的分子基础。

A hallmark of plant stress is the accumulation of the red or purple flavonoids. Many evidences proved that flavonoids played the important roles in plant stress protection. So the contribution of plant flavonoids to UV-B protection, disease resistances and resistances to aluminum toxicity were outlined. Progress on defining the mechanisms that controlled the amounts and varieties of flavonoids produced in plants in response to diverse environmental stress was also discussed.
