Figure 2: Maximum-likelihood dendrogram of full-length genome of severe acute respiratory syndrome coronavirus-2 virus and representative betacoronaviruses. The nucleotide sequences are aligned using Muscle algorithm with bootstrap values of 1000 replicates. The scale bar indicates the branch lengths measured in number of nucleotide substitution rate per site, estimated by the Jukes-Cantor model. The green color triangle indicates severe acute respiratory syndrome coronavirus-2 virus isolates from Asian countries like India (IND), China (CHI), Pakistan (PAK), and South Korea (KOR), pink color code for European countries such as Spain (ESP), Greece (GRC), France (FRA), and Italy (ITA), purple color code for Australian continent (AUS), cyan blue color indicates African continent (South Africa, ZAF), yellow color code for south American country such as Brazil (BRA), blue color code for North American country like USA, black for South-East Asian country (Malaysia, MYS), and orange color code for Middle East country like Iran. Similarly, black square box is an indicted for severe acute respiratory syndrome severe acute respiratory syndrome-like-betacoronavirus isolated from Bat (Rhinolophus sinicus) and red square box is for Pangolin-like coronavirus (Manis javanica, Malayan pangolin). Severe acute respiratory syndrome-coronavirus is indicated in brown color hexagon shape, and Middle East respiratory syndrome coronavirus is indicated in blue color diamond shape isolated from a patient in 2003, infected with severe acute respiratory syndrome at Saudi Arabia.
