Family: Bromoviridae
Genus: Ilarvirus
Acronym: ApMV
ApMV Synonyms: Apple infectious variegation virus, European plum line pattern virus, Plum line pattern virus, Rose infectious chlorosis virus, Rose mosaic virus
Causes mosaic in apple, and line-pattern in plum, although other viruses cause similar symptoms in plum. In rose it causes mosaic symptoms (chlorotic bands and lines) which are not readily differentiated from those caused by prunus necrotic ringspot virus. It occurs naturally in hop and in birch in leaves of which it causes chlorotic lines and rings. It may be transmitted... more info

Acronym: ApMV
ApMV Synonyms: Apple infectious variegation virus, European plum line pattern virus, Plum line pattern virus, Rose infectious chlorosis virus, Rose mosaic virus
Causes mosaic in apple, and line-pattern in plum, although other viruses cause similar symptoms in plum. In rose it causes mosaic symptoms (chlorotic bands and lines) which are not readily differentiated from those caused by prunus necrotic ringspot virus. It occurs naturally in hop and in birch in leaves of which it causes chlorotic lines and rings. It may be transmitted by natural root grafts. Apple mosaic was one of the first ‘variegations’ shown to be transmissible by grafting.
Apple mosaic virus is one of the pathogens responsible for rose mosaic disease. Symptoms vary, and can include line patterns, ringspots, and mottle. It is spread by propagating from infected plants, and can be brought under control with a good indexing program.
In apple, ApMV causes a variety of leaf symptoms and reductions in fruit yield of varying severity. In apple, this virus is spread mainly by grafting to infected rootstocks. ApMV also occurs in hops, birch and plum. It is difficult to transmit mechanically from woody to herbaceous hosts, but is easily transmitted by sap among herbaceous plants.
