Discovery of two small circular ssDNA viruses associated with the whitefly Bemisia tabaci

Discovery of two small circular ssDNA viruses associated with the whitefly Bemisia tabaci The complete genome sequences of two novel small circular DNA viruses isolated from sweet-potato whiteflies collected in central-West (AdDF) and Southeast (AdO) regions of Brazil were determined by Next Generation Sequencing (NGS), and confirmed by cloning and Sanger sequencing. The genomes are 2,199 and 2,211 nt-long, respectively, encoding a putative coat protein (CP) and a replication-associated protein (Rep) and showing a genomic organization typical of viruses from the family Genomoviridae. Phylogenetic analysis with deduced amino acid sequences of Rep indicates that the virus from AdO is closely related to other members of the genus Gemycircularvirus, while the virus from AdDF is distantly related to other genomovirus. It was thus classified in a putative new genus, for which the name “Gemybolavirus” is proposed. These new genomoviruses are tentatively named “Bemisia associated gemybolavirus AdDF”, and “Bemisia associated gemycircularvirus AdO”. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

The complete genome sequences of two novel small circular DNA viruses isolated from sweet-potato whiteflies collected in central-West (AdDF) and Southeast (AdO) regions of Brazil were determined by Next Generation Sequencing (NGS), and confirmed by cloning and Sanger sequencing. The genomes are 2,199 and 2,211 nt-long, respectively, encoding a putative coat protein (CP) and a replication-associated protein (Rep) and showing a genomic organization typical of viruses from the family Genomoviridae. Phylogenetic analysis with deduced amino acid sequences of Rep indicates that the virus from AdO is closely related to other members of the genus Gemycircularvirus, while the virus from AdDF is distantly related to other genomovirus. It was thus classified in a putative new genus, for which the name “Gemybolavirus” is proposed. These new genomoviruses are tentatively named “Bemisia associated gemybolavirus AdDF”, and “Bemisia associated gemycircularvirus AdO”.
