Abstract
Gymnema sylvestre is a tropical climber species that is widely used in traditional medicine since ages. In the present study, the transcriptome datasets of G. sylvestre available in public domain were screened for the presence of novel plant viral sequences and a putative novel virus tentatively named as Gymnema sylvestre virus 1 (GysV1) was identified. Coding-complete genome segments of GysV1 that are 6.35kb (RNA1) and 3.98kb (RNA2) long possessed a single large open reading frame coding for a polyprotein. BLASTp, sequence identity and phylogenetic analyses revealed the relatedness of GysV1 to the members of the subgenus Cholivirus (genus Sadwavirus; family Secoviridae; order Picornavirales). Based on the species demarcation criteria of the family Secoviridae, GysV1 can be regarded as a new cholivirus member.
