Cherry leaf roll virus (CLRV) is a plant pathogenic virus of the subfamily Comovirinae, family Secoviridae, order Picornavirales.

Hosts

The Cherry leaf roll virus infects a wide variety of woody plants and produces different symptoms by host. Symptoms of infection were first identified in walnut and sweet cherry trees.[1] The virus is known to infect at least 36 plant families and natural hosts include olive, elm, ash, elderberry, beech, rhubarb, dogwood, and lilac.[1][2]

Symptoms

Symptoms include leaf roll, leaf yellowing, early dropping of leaves, stunted growth, and plant dieback.[1][3] Plants can also be infected without exhibiting symptoms.[1][4]
