Emaravirus Emaravirus Emaravirus is a genus of plant viruses. The genus has more than six species, including: "European mountain ash ringspot-associated virus" (type species), "Fig mosaic virus", "Pigeonpea sterility mosaic virus", "Raspberry leaf blotch virus", "Rose rosette virus" and Maize red stripe virus. "European mountain ash ringspot-associated virus" is associated with a leaf mottling and ringspot disease of European mountain ash "Sorbus aucuparia". It can be transmitted by grafting and possibly mites. The virion particle is between 80-100 nm and consists of an enveloped ribonucleocapsid that exhibits helical symmetry. The genomes are segmented, consisting of four strands of negative-sense single-stranded RNA.
Sorbus aucuparia and white, while the heart-wood is brown. In almost treeless regions it is used as firewood. The leaves are sometimes used as fodder for livestock while the fruit are used against erysipeloid infections in domestic pigs and goats. Bark of the plant was used to dye wool brown or red. Honey from "S. aucuparia" flowers is strongly aromatic and has a reddish color. "Sorbus aucuparia" is planted in mountain ranges to fortify landslides and avalanche zones. It is also used as an ornamental plant in parks, gardens, or as an avenue tree. Ornamental cultivars include 'Asplenifolia', which has divided and
