MYB转录因子调控植物黄酮醇生物合成的研究进展
Research progress on the regulation of flavonol biosynthesis in plants by MYB transcription factors
摘要
Abstract
Flavonols are the most widely distributed and abundant flavonoids in the plant kingdom.They play crucial roles in plant growth and development,stress resistance,and adaptation to environmental challenges,while also possessing potent antioxidant properties that are of significant importance to human health.Given the multiple values of flavonols,elucidating the regulatory mechanisms of their biosynthetic pathways has become a research hotspot.As one of the largest families of transcription factors in plants,MYB transcription factors play a central regulatory role in the biosynthesis of flavonols.MYB can directly regulate downstream target genes,collaborate with bHLH and WD40 proteins to form MBW complexes for coordinated regulation,and integrate environmental signals such as light,temperature,and drought to achieve precise control of flavonol synthesis.This paper reviewed the physiological functions and biosynthetic pathways of flavonols,with a particular focus on the structural characteristics of MYB transcription factors and their molecular mechanisms in regulating flavonol synthesis,summarized key MYB transcription factor members involved in flavonol regulation across different species and their functions,while addressing the limitations of current research and outlining future directions,aiming to provide a theoretical basis for improving the nutritional value of crops and breeding new cultivars of flowers with novel colors.[Ch,4 fig.1 tab.78 ref.].关键词
