Far-Red Light Photoacclimation Rewires Antenna-Photosystem Organization in Cyanobacterial Cells

Thylakoid membrane remodeling regulates photosynthetic activity in response to changing light, but it is unknown whether such membrane-scale control exists in cyanobacteria, which lack the spatially segregated membrane domains of green algae and plants. Using cryo-electron tomography guided by single-cell hyperspectral correlative imaging, we link spectral acclimation state to thylakoid…
