Abstract Anthocyanins, a flavonoid group of polyphenolic compounds, are important human health-promoting pigments responsible for the red and blue colors of horticultural products such as fruits, flowers, and leaves. The anthocyanin biosynthetic and transport pathways are well known. Key regulatory factors involved in these pathways have been characterized in many plant species. Recently, it has been found that regulatory proteins controlling anthocyanin biosynthesis at the transcriptional and post-transcriptional levels are found to be differentially modulated by environmental and biological factors such as light, temperature, sugars, and hormones. In this review, a simplified model for the role of environmental and developmental factors in the modulation of the anthocyanin biosynthesis pathway in horticultural plants is proposed, with emphasis on the coordinated regulation of the key transcriptional MYB-bHLH-WD40 (MBW) complex.
