Cherry virus A
Family : Betaflexiviridae
Genus : Capillovirus
Acronym : CVA
Introduction
Cherry virus A (CVA) is a graft-transmissible member of the genus Capillovirus that infects different stone fruits. Sweet cherry (Prunus avium L; family Rosaceae) is an important deciduous temperate fruit crop in the Western Himalayan. The single-stranded RNA genome of capilloviruses consists of two ORFs. ORF1 encodes a large polyprotein containing the replication-associated proteins plus a coat protein, and ORF2, located within a different reading frame, encodes a movement protein.
