Phylogenetic tree of sulfate transporter-like proteins in cyanobacteria. The clustalw program was used to align the protein sequences, and the tree was generated in the treeview program. Abbreviations for species names: slr/sll, Synechocystis PCC6803; alr/all, Anabaena PCC7120; tlr/tll, Thermosynechococcus BP1; Npun, Nostoc punctiforme; Tery, Trichodesmium erythraeum; PMT, Prochlorococcus marinus MIT9313; PMM, Prochlorococcus marinus MED4; Pro, Prochlorococcus marinus SS120; SynW, Synechococcus WH8102; 7002, Synechococcus PCC7002; Cwat, Crocosphaera watsonii WH8501; Avar, Anabaena variabilis ATCC29413; and Selo, Synechococcus elongatus PCC7942. Marine species are represented by 7002, Tery, Cwat, SynW, Pro, PMT, and PMM.
