Fig. 2. The presence of pilus-related proteins in cultured marine picocyanobacteria strains.

Fig. 2

Pilus proteins from Synechococcus sp. WH7803 were used for the BLASTp search. Log10 E-value scales are shown (1 to <10−10, white to red; and 1 to <10−70, white to blue). Black cells represent proteins that were not detected (ND). Numbers in the ‘PilE’ column indicate the genomic distance between pilE and pilA1 homologues (e.g. 1 denotes pilE and pilA1 are contiguous in the genome; 0 denotes the same gene gave homology to both pilE and pilA1 due to the conserved N-terminal of the protein; # denotes both genes are separated by >20 genes). PilC, PilQ and PilB were used to determine the presence of the pilus transmembrane apparatus. ComEA and ComEC were selected to determine the presence of the additional machinery required for competence.
