摘　　要：Genomoviridae is a virus family belonging to circular replication associated protein encoding ssDNA(CRESS-DNA)viruses,which have diverse genomic architecture and are widely distributed among different ecosystems.In this study,we characterized 39 novel genomovirus genomes including 3 from wild egrets,9 from wild cranes,as well as 27 from wild finches in three different types of cloacal swabs of wild bird sampled in the station of Xinqing bird ringing,Maoershan Nature Reserve in Heilongjiang Province,Changbai Mountain in Jilin Province,and Hangzhou Wetland Park in Zhejiang Province,China.Here,using a Rep sequence phylogeny-based analysis,we divided the 39 genomoviruses into 8 genera within the family Genomoviridae,including Gemycircularvirus(n=20),Gemykibivirus(n=3),Gemygorvirus(n=2),Gemyvongvirus(n=2),Gemykolovirus(n=3),Gemykrogvirus(n=6),Gemytondvirus(n=1),Gemyduguivirus(n=1)and one unclassified genomovirus.The 39 genomovirus genomes belong to 36 species(27 of which are new)based on the currently accepted genomovirus pairwise nucleotide sequence identity species demarcation threshold of 78%.Overall,the research enriches our knowledge of CRESS-DNA viral diversity in China and emphasizes the prevalence of genomoviruses in nature.
