Abstract

Summary Anthocyanins are natural pigments that accumulate only in light‐grown and not in dark‐grown Arabidopsis plants. Repression of anthocyanin accumulation in darkness requires the CONSTITUTIVELY PHOTOMORPHOGENIC 1/ SUPPRESSOR OF PHYA ‐105 ( COP 1/ SPA ) ubiquitin ligase, as cop1 and spa mutants ...
