Complete genome sequence of a tentative new caulimovirus from the medicinal plant Atractylodes macrocephala

Abstract

A total of nine contigs related to caulimovirus-like sequences were detected using high-throughput paired-end RNA sequencing. An attempt to find the plant sample infected with this type of virus identified the medicinal plant Atractylodes macrocephala Koidzumi showing mild mottle symptoms. Subsequently, the complete DNA genome sequence of the Atractylodes virus was determined. The 8,105-nt genome of the virus was composed of six open reading frames and displayed the highest nucleotide sequence identity (70 %) with soybean Putnam virus. Based upon the symptoms observed on the source plant, we propose to refer to this new member of the genus Caulimovirus as atractylodes mild mottle virus.
