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 The tallest "S. aucuparia" in the United Kingdom stands in the Chiltern Hills in South East England. This exceptional specimen is 28 m tall and has a trunk diameter of 56 cm. In Germany, an unusually large specimen is located near Wendisch Waren, a village in Mecklenburg-Vorpommern. This tree stands at more than 15 m tall, is around 100 years old, and has a diameter of 70 cm. The tallest known "S. aucuparia" in Ireland is an 18 m tall specimen at Glenstal Abbey, County Limerick. "Sorbus aucuparia" is pollinated by bees and flies. Its seeds are not digested by
