Phylogeny and structural analysis of PSI and PSII. (A). The phylogenetic tree of the LHCA subfamily. (B). The phylogenetic tree of the LHCB subfamily. The detailed information, including gene IDs and bootstrap values, for Fig. 1A and B is provided in Figs. S2 and S3, respectively. (C).The left PSI-LHCI structure represents Chlamydomonas reinhardtii from the Chlorophyta (PDB ID: 6IJO). The middle PSI-LHCI structure corresponds to Physcomitrium patens from the Bryophyta (PDB ID: 6L35). The right PSI-LHCI structure pertains to Pisum sativum from the Angiospermae (PDB ID: 4XK8). the Cyanidioschyzon merolae PSI-LHCI supercomplex is provided in Fig. S4 (D). The PSII-LHCII complexes from C (PDB ID: 6KAF) and P. sativum (PDB ID: 5XNM).
