Genome comparisons of Subcluster A1 phages Barriga and Nhonho. Each genome map is shown with the coordinates in kbp flanked by genes represented as boxes positioned above (transcribed rightwards) or below (transcribed leftwards); the phams to which each gene belongs are indicated above or below genes (and colored accordingly) with the number of pham members in parentheses. Pairwise nucleotide sequence similarity between genomes is shown as spectrum-colored shading between the genomes as determined with BLASTN; greatest similarity is shown in purple and weakest similarity (above a threshold level of 10−4) shown in red. Barriga and Nhonho have similar gene contents and genome architectures but with a notable insertion/deletion between the recB and immunity repressor genes. The nucleotide similarity between the two phages is quite high in the capsid genes in the left arm, disappears almost entirely downstream of the major capsid protein, and reemerges in the minor tail proteins
