Complete nucleotide sequence of chrysanthemum mosaic-associated virus, a novel emaravirus infecting chrysanthemum.

Here, we report the complete genome sequence of chrysanthemum mosaic-associated virus (ChMaV), a putative new member of the genus Emaravirus. The ChMaV genome comprises seven negative-sense RNA segments (RNAs 1, 2, 3a, 3b, 4, 5, and 6), and the amino acid sequences of its RNA-dependent RNA polymerase (RNA1), glycoprotein precursor (RNA2), nucleocapsid protein (RNA3), and movement protein (RNA4) showed the closest relationship to pear chlorotic leaf spot-associated virus. Phylogenetic analysis showed that it clusters with emaraviruses whose host plants originate from East Asia.
