Genomic characterization between Pelagibacter and pelagiphage according to the GANTC motif. a Distribution of GANTC motif methylation in both strands of Cand. Pelagibacter Giovannoni NP1 genome. The inner blue and red bars indicate the coding sequence region of the genome. The methylation fraction bar for each strand is red for values ≥ 0.9, orange for ≥ 0.6, and bright yellow for ≥ 0.3. The prophage region of the genome is highlighted by a purple bar from Pleška et al. [26]. The GANTC motif depletion region is marked through a multiscale signal representation (MSR) analysis. b, Phylogenetic tree of pelagiphages of the head–tail connector protein. Red boxes represent the GANTC depletion subgroups of pelagiphage. c The GANTC motif density comparisons between genomes of Pelagibacter and pelagiphage
