Yellow vein net disease of Calendula associated with Cucumber mosaic virus has been reported previously (Naqvi & Samad, 1985) which belongs to a plant pathogenic virus in the family Bromoviridae. The study of the CP gene of begomovirus complex isolates from northern India and their similarity with other important crop-infecting begomoviruses reveals the broadened host range in India.
PNRSV is transmitted by pollen, seed and vegetative propagation methods (FIORE et al., 2008), being a positive-sense RNA virus with a tripartite genome that belongs to the genus Ilarvirus of the Bromoviridae family.
These viruses are classified in the Bromoviridae family, genus Ilarvirus (ApMV) or Secoviridae family, genus Nepovirus (ArMV).
AMV is the type member of the genus Alfamovirus in the Bromoviridae family of plant viruses.
Cucumber mosaic virus (CMV, genus: Cucumovirus, family: Bromoviridae) is one of the most widespread plant viruses in the world with extensive host range infecting about 1000 species including cereals, fruits, vegetables and ornamentals and its economic impact, CMV has been considered as one of the most important viruses (Roossinck, 1999; Palukaitis and Arenal, 2003).
