Gene Class
Reaction to wheat streak mosaic virus
Symptoms
Caused by a virus transmitted by the wheat curl mite (Aceria tulipae). Mites are dispersed from volunteer wheat and alternate hosts to newly emerging wheat by wind. Symptoms include stunting and parallel green- yellow streaks on leaves. Leaf margins are often rolled toward the midrib by feeding activity of the mites. Heads that form may be totally or partially sterile. Favored by early planting dates. Barley, corn, rye and many grasses can serve as alternate hosts for both the mite and virus.
