Wheat yellow leaf virus (WYLV) is a wheat (Triticum spp. L.), barley (Hordeum vulgare L.), rye (Secale cereale M.Bieb.), and oat (Avena sativa L.) pathogenic virus of the family Closteroviridae.[1] WYLV virions are 1600–1850 nm in length and 10 nm in diameter.[2][3] The virus, like other members of its genus, is transmitted by aphids.[2] Identified vectors include Rhopalosiphum padi L. and R. maidis Fitch. (Aphididae).[2][4] The virus has been identified in crop plants in Japan, China, and Italy.[2] Native host plants include Italian ryegrass (Festuca perennis Lam.) in Europe and Agropyron tsukushiense var. transiens Ohwi in Japan.[2] The virus proliferates in the phloem of its host plants, interfering with the plant's ability to produce sufficient chlorophyll (Chlorosis), causing the leaves to yellow and the plant to die.[2]
