Visible light impacts the biology and evolution of non-photosynthetic yeast
A new publication from CeMEB members Anders Blomberg and Jonas Warringer concludes that visible light can affect organisms even if they are not photosynthetic.
Cellular responses to stress from visible light remain poorly understood, despite being a regular part of the life cycle of many organisms. In this article, we developed a method for measuring growth under visible light stress, and used it to screen for light sensitivity in yeast Saccharomyces cerevisiae.
We conclude that yeast photobiology is multifaceted and that protein kinase A plays a key role in the ability of cells to grow upon visible light exposure. We propose that visible light impacts on the biology and evolution of many non-photosynthetic organisms and have practical implications for how organisms are studied in the laboratory, with or without illumination.
