The antenna of far-red absorbing cyanobacteria increases both absorption and quantum efficiency of Photosystem II
Abstract
Some cyanobacteria acclimate to far-red light by integrating chlorophyll f into their photosystems. Additional chlorophylls typically slow down charge separation but here the authors show that charge separation in chlorophyll-f-containing Photosystem II is faster in the presence of red-shifted allophycocyanin antennas.
