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.cite journal | last = Fauquet | first = M.

Identified vectors include "Rhopalosiphum padi" L. and "R. maidis" Fitch. (Aphididae).cite book | last = Vidhyasekaran | first = Perumal | title = Concise Encyclopedia of Plant Pathology | publisher = CRC Press | date = 2004| pages = 563 | isbn = 978-1560229438] The virus has been identified in crop plants in Japan, China, and Italy. Native host plants include Italian ryegrass ("Lolium multiflorum" Lam.) in Europe and "Agropyron tsukushiense" var. "transiens" Ohwi in Japan. 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.
