title: Letter to the editor: Characterization of a Grapevine leafroll-associated virus 3 from India showing incongruence in its phylogeny.
abstract: Survey conducted during 2010-2011 in the vineyards of Nashik and Pune regions of India revealed the association of an Ampelovirus antigenically related to Grapevine leafroll-associated virus 3 (GLRaV-3) with seven cultivars of grapevine. Upon sequencing of the coat protein (CP) and partial heat shock protein 70 homologue (HSP70h) genes of GLRaV-3 present in the cultivar Cabernet Souvignon showed distinct grouping behaviour. It clustered in group 2 and group 1 on the basis of CP and HSP70h sequences, respectively. Incongruent clustering pattern observed on the basis of two genomic regions suggest that GLRaV-3 is a distinct isolate from India.
