Complete genome sequence of a new badnavirus infecting a tea plant in China

The complete genome of a novel virus, provisionally named "Camellia sinensis badnavirus 1" (CSBV1), was identified in tea plant ( Camellia sinensis ) leaves collected in Anhui Province, China. The genome of CSBV1 consists of 8,195 bp and possesses three open reading frames (ORFs), sharing 68.6 % nucleotide sequence identity with the genome of Camellia lemon glow virus (CLGV) from Camellia japonica . The genome organization of CSBV1 is highly similar to that of members of the genus Badnavirus (family Caulimoviridae ). Phylogenetic analysis revealed that CSBV1, CLGV, and cacao swollen shoot virus form a separate clade within the genus Badnavirus , suggesting that CSBV1 is the first badnavirus infecting C. sinensis.
