| Popis: | The complete nucleotide sequence of a new RNA mycovirus in the KY isolate of Phomopsis longicolla Hobbs 1985 and its protoplasts subcultures p5, p9, and ME711 was discovered. The virus, provisionally named Phomopsis longicolla RNA virus 1 (PlRV1), was localized in mitochondria and was determined to have a genome 2822 nucleotides long. A single open reading frame could be translated in silico by both standard and mitochondrial genetic codes into a product featuring conservative domains for an RNA-dependent RNA polymerase (RdRp). The RdRp of PlRV1 has no counterpart among mycoviruses, but it is about 30% identical with the RdRp of plant ourmiaviruses. Recently, new mycoviruses related to plant ourmiaviruses and forming one clade with PlRV1 have been discovered. This separate clade could represent the crucial link between plant and fungal viruses. |
