Anthocyanins, a class of flavonoids, are recognized for their diverse functions in plant development and beneficial effects on human health. Many of the genes encoding anthocyanin biosynthesis enzymes and the transcription factors that activate or repress them have been identified. Regulatory proteins that control anthocyanin biosynthesis by regulating the expression of different structural genes at the transcriptional and post-transcriptional levels are differentially modulated by environmental and biological factors such as light, temperature, sugar and hormones. This minireview summarizes the recent findings contributing to our understanding of the role of sugars and hormones in the modulation of the anthocyanin biosynthesis pathway with emphasis on the coordinated regulation of the critical transcriptional R2R3-MYB/bHLH/WD40 (MBW) complex in Arabidopsis.

Seed color is a key agronomic trait in crops such as peanut, where it is a vital indicator of both nutritional and commercial value. In recent years, peanuts with darker seed coats have gained market attention due to their high anthocyanin content. Here, we used bulk segregant analysis to identify the gene associated with the purplish-red coat trait and identified a novel gene encoding a basic/helix-loop-helix transcription factor, PURPLE RED SEED COAT1 (PSC1), which regulates the accumulation of anthocyanins in the seed coat.

Anthocyanins are a type of water-soluble pigments widely distributed in colorful plants, which have been extensively used in food and cosmetics industry. The current production of anthocyanins heavily depends on extraction from plant materials, which leads to low purity and inconsistency among batches. Compared with conventional extraction, microorganism-mediated production of anthocyanins has advantages such as a short production cycle, high purity, low waste production, low energy requirements, and consistency between different batches.

American elderberry juice (EBJ) and fermented elderberry juice (EBF) were spray dried using two different carriers: S. cerevisiae yeast (SC), used for juice fermentation and as encapsulating agent, and pea protein, to produce protein-polyphenol ingredients. The spray drying (SD) performance (solids recovery, SR; phenolic retention, PR) and quality attributes (physicochemical and functional properties, phytochemical content and bioaccessibility after in vitro digestion) of eight treatments of spray dried elderberry particles were determined.
