Circular genome maps of the chromosome 1 (A), the chromosome 2 (B), the plasmid A (C), and the plasmid B (D) in Aquincola tertiaricarbonis RN12 strain, from outside to inside indicate the following: Circle 1: indicator of genome size; Circle 2 and 3: coding sequences in plus and minus strand, different colors represent the functional classification of COG with different CDS; Circle 4: the distribution of rRNA and tRNA; Circle 5: G + C content (the outer circle shown in red is greater than the average content, and the inner circle shown in green is less than the average content); Circle 6: GC skew (green represents the GC skew > 0, orange represents the GC skew < 0)
