B. Higher Plant

Fig. 5 Connectivity of the chlorophyll networks in PSI from (a) cyanobacteria and (b) higher plants. The thickness of a line between two chlorophylls is proportional to the logarithm of the excitation transfer rate between them. Only the strongest connections are shown, for simplicity. Chlorophylls of the LHCI belt in plant PSI are rendered in gray in (b). Figure made using Protein Data Bank files 1JBO and IQZV with the program VMD.
