Origins and photophysiological features of the five marine cyanobacteria used in this study.

PBS, phycobilisome; Pcb, Prochlorophyte chlorophyll binding protein; NPQ, non photochemical quenching of fluorescence induced at 300 µmol photons m−2 s−1; σPSII, PSII effective absorbance cross section for blue light; |σI|, magnitude of the effective target size for PSII photoinactivation by blue light; RPSII, PSII repair rate; ETOL, maximal variable irradiance (n = 4±s.e.).
