Diversification of the Light-Harvesting Complex Gene Family via Intra- and Intergenic Duplications in the Coral Symbiotic Alga Symbiodinium
Fig 2
Composition and gene distribution of the S. minutum LHCR and LHCF proteins.
(A) Different colors represent phylogenetic groups and the subgroupings within each group recovered in the phylogenetic tree in Fig 1. Group F1 is represented as a single box for clarity (see Fig. 2B). Numbers in the boxes indicate subgroupings within the F4 and R3 groups supported in the phylogenetic tree, where ‘0’ represents the F4 group members with no subgroupings found in the tree. (B) Detailed distribution pattern of group F1. Different color codes indicate subgroupings in the tree, with subgroup ‘0’ showing no phylogenetic affiliation with any other subgroups. Non-F1 members are shown in the gray boxes with the names of the groups. The arrowhead indicates the gene locus possessing the SPLR motif (see text). The star indicates the fusion gene of LHCR and LHCF families. Numbers with ‘#’ above the boxes indicate the unit labels for each protein unit in polyproteins.
