Fig 1 — A circular view of the phylogenomic tree represents the evolutionary transmittance of Brazilian SARS-CoV-2 isolates along with the reference genome (Wuhan-Hu-1). Each color of nodes and clades are represented a corresponding genomic isolated year. The lengths of the branches are proportional to the evolutionary distances. The outer circular arrow indicated the evolutionary flow of Brazilian SARS-CoV-2 isolates.
