Abstract
A potyvirus was isolated from diseased Cymbidium pendulum and C. tigrinum epiphytic orchids collected from Sikkim in northern India. ELISA, RT-PCR and Northern blot analysis revealed the association of potyvirus infection with disease symptoms. The sequencing of a RT-PCR-amplified amplicon using potyvirus group-specific primers showed that this virus is distinct but most closely related to Calanthe mild mosaic virus. This paper reports the occurrence of potyvirus in wild orchids especially in Cymbidium spp.
