Maximum likelihood phylogenies and motif patterns of four lectin families in cyanobacteria. A GRFT lectin family, with Rhodophyta GRFT from Griffithsia sp. (GenBank accession AY744144.1) used as the out-group. B OAAH lectin family, with four homologous sequences from Kappaphycus alvarezii (numbered as Rhodophyta OAAH-1–4) used as the out-group; C Mannan-binding lectin family, with the Bacteroidota lectin sequence from Polaribacter reichenbachii used as the out-group; D Legume lectin-like lectin family, with homologous sequences from Rhodochaete parvula (numbered as Rhodophyta legume 1–3) used as the outgroup.. The number pairs on the branches represent both SH-aLRT test and bootstrap values with 1000 replicates. Accession numbers for the sequences data are provided as supplementary Table S1
