Abstract: 
The facultatively photosynthetic bacterium Rhodobacter sphaeroides harbours an unusual light, oxygen, voltage (LOV) domain protein, RsLOV. While showing a characteristic photocycle, the protein lacks a C-terminal output domain, similar to PpSB2 in Pseudomonas putida. Oxygen tension and light quantity are the two factors mainly responsible for controlling the expression of photosynthesis genes in R. sphaeroides. Two photoreceptor proteins are known to be involved in this regulation: the intensively studied AppA protein and the more recently identified cryptochrome-like protein CryB. Here we show by transcriptome and physiological studies that RsLOV is also involved in the regulation of photosynthetic gene expression. Our data further hint at a connection between RsLOV, carbohydrate metabolism and chemotaxis, as well as with the cellular response to photooxidative stress. RsLOV affects not only blue light-dependent gene expression but also redox-dependent regulation.
