英文摘要Photoreceptors are found in all kingdoms of life and bacteriophytochromes (Bphps) are the most abundant photo-sensing receptors in bacteria. Interestingly, BphPs have been linked to some bacterial physiological responses, yet most of the biological processes they regulate are still elusive, especially in non-photosynthetic bacteria. Here, we show that a bacteriophytochrome (CmoBphp) from a deep-sea bacterium Croceicoccus marinus OT19 perceives infrared light (wavelength at 940 nm) and transduces photo-sensing signals to a downstream intracellular transduction cascade for better growth. We discover that the infrared light-mediated growth promotion of C. marinus OT19 is attributed partly to the enhancement of pyruvate and propanoate metabolism. Further study suggests that CmoBphp plays a crucial role in integrating infrared light with intracellular signalling to control the bacterial growth and metabolism. This is the first report that deep-sea non-photosynthetic bacteria can sense infrared light to control growth through a bacteriophytochrome photoreceptor, thus providing new understandings towards light energy utilization by microorganisms.
