β-Carbonic anhydrases integrate CO2 and light cues to coordinate photosynthesis in tomato.
This work identifies two tomato β-carbonic anhydrases responsive to deficient CO2 and establishes chloroplast βCA1 as a key integrator of CO2 and light cues that optimizes photosystem performance through modulation of pmf partitioning and reveals stromal pH regulation as a previously unrecognized mechanism for optimizi...
