Abstract
We report the complete genome sequence of a new avastrovirus of goose-origin (FLX). The 7299-nt-long genome consisted ofthree overlapping open reading frames (ORFs) that were in different reading frames.Pairwise comparisons showed that the FLX genome was59% identical to its closest relatives and that the levels of amino acid identity shared by FLX with other astroviruses did not exceed 54% in ORF1a, 66% in ORF1b, and 50% in ORF2,respectively. Phylogenetic analysis based on the amino acid sequence ofthefull-length ORF2 demonstrated that FLX was highly divergent from all other avastroviruses.At the amino acid level the complete capsid region ofFLX shared genetic distances of 0.574-0.719 with three official avastrovirus species, suggesting that it can be classified as a member of a novel species in the genusAvastrovirus.
