摘要

Anthocyanin accumulation is a key determinant of fruit quality and market value, influenced by a complex regulatory network. This review synthesizes recent advances in understanding the multifaceted regulation of anthocyanin accumulation, with a primary focus on the core MYB–bHLH–WD40 (MBW) protein complex. We provide a comprehensive analysis of the genes governing the MBW complex, delving into both transcriptional control and post-translational modifications that fine-tune its stability and activity. Furthermore, we examine how internal hormonal signals and external environmental cues are integrated upstream to modulate this central regulatory machinery, thereby precisely controlling anthocyanin pigmentation. By consolidating these regulatory layers, this review aims to establish a cohesive framework that illuminates the sophisticated molecular hierarchy governing fruit anthocyanin accumulation, providing a foundation for future research and potential biotechnological applications in fruit improvement.
