The complete genome sequence of Stellaria aquatica virus A, a new member of the genus Alphacarmovirus, family Tombusviridae.

A new member of the genus Alphacarmovirus was detected in Stellaria aquatica using high-throughput RNA sequencing analysis. The complete genome sequence of this new virus isolate, tentatively named "Stellaria aquatica virus A" (StAV-A), comprises 4,017 nucleotides with five predicted open reading frames (ORFs) and has a typical alphacarmovirus genome organization. Pairwise comparison of StAV-A with selected members of family Tombusviridae showed 44-58%, 32-64%, and 19-49% sequence identity for the overall nucleotide sequence, polymerase, and coat protein, respectively. Phylogenetic analysis of polymerase sequences places StAV-A alongside other members of the genus Alphacarmovirus in the family Tombusviridae.
