Anthocyanin Accumulation is Controlled by Layers of Repression

Preventing too much of a good thing: epigenetic regulation limits sucrose‐induced anthocyanin production in Arabidopsis

“…Beyond their aesthetic appeal, the accumulation of anthocyanins in flowers and fruits is crucial for attracting pollinators and seed dispersers, respectively, and these pigments confer a number of protective benefits in vegetative tissues (Davies et al ., 2022). However, having too much of a good thing can be problematic, and the overaccumulation of anthocyanins in green tissues may result in reduced photosynthetic efficiency (Allan et al ., 2019). Plants have therefore evolved intricate regulatory networks to ensure that anthocyanins are produced in the correct tissue, at the right time, and at the proper concentration given their ambient conditions.…”
