花青素(Anthocyanins)是黄酮类多酚化合物,在植物体内各个器官广泛分布,在维持植物正常生理活动中发挥重要作用。作为一种天然可食用色素,花青素因具有强抗氧化性,能够增强人体免疫力,具有保护视力和美容养颜等功效。bHLH转录因子作为植物中仅次于MYB转录因子的第二大转录因子超家族,在植物花青素的合成过程中起着重要调控作用。bHLH蛋白不仅能直接作用于花青素合成相关结构基因,还能通过与MYB、WD40蛋白形成复合体的形式调控植物花青素的生物合成,且bHLH转录因子发挥作用的过程中受环境因子以及激素信号的影响。本文综述了花青素生物合成途径及其调控机制,总结了bHLH类转录因子的结构特征、参与花青素合成调控的主要方式以及环境因素和激素信号对其在花青素积累过程中发挥作用的影响,以期为进一步研究花青素生物合成调控机制、花色调控、园艺植物育种等奠定基础。
Anthocyanins, a type of flavonoid polyphenolic compounds, are widely found in various plant organs and play a crucial role in maintaining programmed physiological activities. As natural edible pigments, anthocyanins are powerful antioxidants that can boost the human immune system and provide benefits such as vision protection and beauty promotion. bHLH transcription factors, as the second largest transcription factor superfamily in plants after MYB, play a significant role in regulating anthocyanin biosynthesis. bHLH proteins not only directly interact with structural genes in anthocyanin synthesis but also form complexes with MYB and WD40 proteins to regulate the process. Their functions are influenced by environmental factors and hormonal signals. This article reviews the anthocyanin biosynthesis pathways and their regulatory mechanisms, including summarization of their structural characteristics, their regulatory mechanisms, and the impact of external environmental factors and hormone signals on bHLH regulation during anthocyanin accumulation. We expect to provide a foundation for further research on anthocyanin regulation, color formulation, and horticultural plant breeding.
