Convergent evolution of SARS-CoV-2 in human and animals
Recently,many SARS-CoV-2 variants including 501Y.V1,501Y.V2 and 501Y.V3 were detected in different regions(Table S1)and drew great attention from all over the world.The 501Y.V1 was firstly isolated in the United Kingdom(UK)(Davies et al.,2020)and featured with 7 substitutions including N501Y as well as 3 deletions in S protein.This variant was identified to increase the viral transmissibility by 56％in comparison with the preexisting strains.Days after this report,another SARS-CoV-2 variant(501Y.V2)featured with N501Y,K417N and E484K substitutions in S protein was supposed to rapidly outcompete the preexisting strains(Tegally et al.,2020)in South Africa.Besides,the 501Y.V3 variant was initially detected in Brazil and has caused rapidly increased infections with SNPs N501Y,K417T and E484K.Of them,N501Y,K417N/T and E484K are of particular interest because the N501Y was shared in all three variants and the K417N/T and E484K were detected simultaneous appeared with N501Y in 501Y.V2 and 501Y.V3.
