Figure 7. The differing genome organizations in the Chuviridae.
(A) ML trees of three main putative proteins conserved among the chuviruses. Viruses with circular genomes (Type I) are shaded blue, while those with segmented genomes (Type II) are shaded red. (B) Structures of all complete chuvirus genomes. Circular genomes are indicated with the arrow (blue) situated at the 3′ end, and the genome is drawn in a linear form for ease of comparison only, being broken at the region of variable sequence (refer to the ‘Materials and methods’). (C) An example showing mapping of sequencing reads to the circular chuvirus genome. The template for mapping contains two genomes connected head-to-tail. The two boxes magnify the genomic region containing abundant sequence variation.
