Title	Phototropin connects blue light perception to starch metabolism in green algae
Description	In photosynthetic organisms light acts as an environmental signal to control their development and physiology, and as energy source to drive the conversion of CO2 into carbohydrates used for growth or storage. The main storage carbohydrate in green algae is starch, which accumulates during the day and is broken down at night to meet cellular energy demands. The signalling role of light quality in the regulation of starch accumulation remains unexplored. Here, we report that in the model green alga Chlamydomonas reinhardtii blue light perceived by the photoreceptor PHOTOTROPIN suppresses starch accumulation. To gain more insight into the molecular mechanism underlying the PHOT-mediated light perception and starch accumulation, we applied we applied mass spectrometry (MS)-based quantitative proteomics to compare WT and phot cells grown in asynchronous photoautotrophic conditions under low light.
