The production of anthocyanin is regulated by light and corresponding photoreceptors. In this study, we found that exposure to blue light and overexpression of CRY1a are associated with increased accumulation of anthocyanin in tomato (Solanum lycopersicum L.). These responses are the result of changes in mRNA and the protein levels of SlHY5, which is a transcription factor. In vitro and invivo experiments...
Anthocyanins are thought to provide photoprotection under stressful conditions. We used two genotypes of Begonia semperflorens with different pigmentation to study the effects of anthocyanins on tolerance of high-light stress. The maximum quantum yield of PSII (Fv/Fm) in red leaves was significantly higher than that in green leaves during and after high-light stress. High light also induced significant...
