Distribution PBS operons inferred from phylogenetic placement of PC and PE subunits. Amino-acid sequences for PC (cpcBA) and PE (cpeBA) sequences were inserted into the respective phylogenetic tree (shown in Figures 4a and b) using the evolutionary placement algorithm in RAxML. Each bar plot shows the distribution of sequences from various samples in the corresponding phylogeny. If sequences were inserted directly on a terminal leaf, the strain/contig name is shown in the plot. For sequences inserted into internal nodes, the node name is given and its position in the tree is shown in Figure 4a or Figure 4b. For collapsed clades, the combined distribution of sequences in the clade is shown. (a, b) PC sequences from the 2009 transect and previous studies (a) and from the 2011 time series (b). (c, d) PE sequences from the 2009 transect and previous studies (c) and from the 2011 time series (d). Pigment type clade designations are shown in boxes with the novel type IIB clade shaded in grey. CalCOFI, West coast of California (California Current); GML, Great Mazurian Lakes; GOF, Gulf of Finland; GS020, Lake Gatun; LB, Lake Balaton; LM, Lake Mondsee.
