Top view (a) and side view (b) of the maps of inter-pigment EET rates. The color bars correspond to rates faster than 1 ps (red), in the 1–10 ps range (thick white) and in the 10–20 ps range (thin black). Inter-pigment rates slower than 20 ps are omitted. The shadings indicate the outlines of AcpPCIs. Group I (green), Group II (blue), and Group III (orange). c EET rates between AcpPCIs and from AcpPCIs to PSI core. The efficient EET pathways from AcpPCIs to PSI core are indicated by magenta arrows. d EET between the Chls viewed from the stromal side. EET pathways from AcpPCIs to PSI core (solid arrows), between the AcpPCIs (dashed arrows). Red arrows: faster than 2 ps; blue arrows: between 2 ps and 5 ps; orange arrows: between 5 ps and 10 ps. P1-P13 represent the AcpPCI-1 to AcpPCI-13 subunits, respectively.
