Dataset for "Photosynthesis-driven interactions in the phycosphere enhance bacterial extracellular superoxide production"

This dataset was collected to investigate the multi-omic mechanisms underlying photosynthesis-driven interactions within the phycosphere, specifically focusing on how these interactions regulate and enhance bacterial extracellular superoxide production under carbon-starvation conditions. Experimental efforts involved co-culturing the cyanobacterium Microcystis aeruginosa and the heterotrophic bacterium Pseudomonas sp. QJX-1 under controlled illumination and carbon-limiting states. Chronological time-course sampling was executed to capture prokaryotic transcriptomic shifts (RNA-seq at 48h and 108h) and untargeted exometabolomic footprints (LC-MS at 48h, 72h, and 108h) to establish the molecular and chemical profiles driving phycosphere microscale redox coupling.
