Abstract
A macluravirus, tentatively named alpinia oxyphylla mosaic virus (AloMV), was identified in Alpinia oxyphylla, and its complete genomic sequence determined. The positively single-stranded RNA genome is comprised of 8213 nucleotides excluding the poly (A) tail, and contains one large open reading frame encoding a polyprotein of 2,626 amino acids. Blastp search showed that the polyprotein of AloMV shared 48%~68% aa sequence identities with other reported macluraviruses. Phylogenetic analysis based on the nucleotide sequence of the polyprotein showed that AloMV, together with all other macluraviruses, clustered into the same group most closely related to cardamom mosaic virus, sharing 66.3% nt and 68% aa sequence identities, respectively. These data above suggest that AloMV represents an isolate of a putative new member within the genus Macluravirus.
