Analysis of secondary replicons. a GC/coverage plot of R1S1 contigs representing the secondary replicons (black diamonds) and primary replicon (single grey triangle). Clusters of contigs forming putative secondary replicons of ~ 220 (coverage of 42–57) and ~ 545 kb (coverage of 87–107) are highlighted with hatched ovals. The single contig outside of the two clusters (43% GC, coverage of 70) encoded four genes annotated as DNA methyltransferase, restriction endonuclease, phage integrase, and hypothetical protein. Not included are two small contigs (1 and 1.3 kb) with high coverage (352 and 162), encoding a transposase and an ATPase, respectively. b Contig mapping of R1S1 contigs to ACAM34 secondary replicons. The red area connects sequences of the ACAM34 (upper horizontal bar) and R1S1 (lower horizontal bar) secondary replicons that share ≥ 80% nucleotide identity, with regions of higher identity shown in darker red. For R1S1, the two horizontal bars represent concatenations of contigs containing mapped sequences (R1S1 contigs not mapping to ACAM34 secondary replicons are not shown). The panel highlights the low degree of conservation between R1S1 and ACAM34 secondary replicons. Mapping was performed with CONTIGuator [31] and visualised using ACT [30]
