Dataset Summary

Title	Dark respiration optimizes photosynthesis carbon yield in cyanobacteria
Description	Cyanobacteria and plants experience daily diel light/dark growth. Respiration in the dark supports survival of the photosynthetic cells by oxidizing storage compound fixed during the day. Dark respiration thus significantly lowers the overall photosynthetic carbon yield. Optimal dark respiration could minimize carbon loss and improve overall photosynthetic carbon yield. However, it is unclear how photosynthetic organisms best allocate carbon resources at night for dark survival and preparation for the reinitiation of carbon fixation reactions upon light exposure. We show in the cyanobacterium Synechococcus elongatus PCC 7942 that an integrative respiratory pathway in the dark helps allocate carbon resource for cell survival and preparation for photosynthesis reinitiation upon photoinduction. Optimization of dark respiration thus represents a unique strategy to enhance photosynthetic carbon yield and potential crop productivity.
