Characteristics of SARS-CoV-2 nucleocapsid gene. A, Phylogenetic analysis of the viral nucleocapsid gene. The SARS-CoV-2 is labeled in red in the phylogenetic trees. Other human coronaviruses from a public database are listed as an outgroup. Evolutionary distances were calculated with the neighbor-joining method. B, Amino acid sequence comparison of the nucleocapsid gene of SARS-CoV-2, IPBCAMS-WH-01/2019 (EPI_ISL_402123), compared with SARS-CoV (NC004718).
