Pie Chart from Scientific Research

Categories of viral genes under positive selection in cryopeg brine (CB) and sea ice brine (SB). Left pie graph , all genes are divided into two groups: genes under positive selection and purifying selection based on pN / pS values. Middle pie graph , genes under positive selection are divided into annotatable and un-annotatable groups by comparing to genes in databases. The number of genes in the above groups is indicated in parentheses after the group names. Right pie graph , the annotatable genes from the middle pie graph are grouped into different gene categories. The percentage of genes assigned to different categories is indicated after the category name. Sample labels: CB, cryopeg brine; SB, sea ice brine; SW: seawater
