EVOLUTIONARY RELATIONSHIP OF UKRAINIAN ISOLATE OF ODONTOGLOSSUM RINGSPOT VIRUS

Odontoglossum ringspot virus (ORSV) is one of the most dangerous viruses decorative orchids. Infection caused by this can reduce phenotypic differences orchids in collections, and as a result lead to their total exhaustion. In study, possible origin Ukrainian isolate ORSV from collection O.V. Fomin Botanical Garden Taras Shevchenko National University Kyiv was investigated. The properties nucleotide sequences RNA-depended RNA-polymerase (RdRp) coat protein gene were examined. RNAs isolated leaves Cymbidium hybridum Garden’s amplified through RT-PCR sequenced. Obtained compared at level with isolates accessible within GenBank. Phylogenetic examination appeared that studied may have common root few South Korean isolates.
