Abstract

The complete genomic sequence of a novel potyvirus from a noni plant in China (Morinda citrifolia) with foliar mosaic and chlorotic symptoms was determined. The genomic RNA consists of 9645 nucleotides (nt) excluding the poly(A) tail, containing the typical open reading frame (ORF) of potyviruses and encoding a large putative polyprotein of 3077 amino acids (aa). Pairwise comparisons showed that the virus shares 48.8%–58.5% sequence identity at the genome sequence level, and 38.5%–53.4% identity at the polyprotein sequence level with other members of the genus Potyvirus. Phylogenetic analysis indicated that the virus is most closely related to jasmine virus T and plum pox virus in the genus Potyvirus. These results suggest that this virus should be considered a distinct member of the genus Potyvirus, and it was tentatively named “noni mosaic virus” (NoMV).
