||P.511 right column top paragraph: "A higher density of PSI reaction centres can be calculated for the plasmalemma of Gloeobacter using the chlorophyll per cell for cells grown at high irradiances, the chlorophyll : P700 ratio from Koenig and Schmidt (1995) and
the cell dimensions from Holt et al. (1994). This density of 18 nmol/m^2 for high light-acclimated cells is not unexpected given the higher PSI : PSII ratio in cyanobacteria and algae with
phycobilins as major light-harvesting components than in vascular plants (Raven 1984 Falkowski and Raven 2007)."
