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 anglica cliffs, quarries and rocky hillsides. It appears to be indifferent to soil pH. Occasional specimens are known from oak woodland. Research suggests Sorbus anglica developed from a cross between Sorbus porrigentiformis and Sorbus aucuparia. Sorbus anglica Sorbus anglica, the English whitebeam, is a species of whitebeam tree in the family Rosaceae. It is uncommonly found in Ireland and the United Kingdom, with an entire British population estimated at about 600 individuals. Sorbus anglica grows as a small tree or shrub, often with multiple stems. The leaves are broader than most other Sorbus, with lobes whose bases are incised up to
