High plains disease : ウィキペディア英語版 | High plains disease High plains disease is a viral disease afflicting wheat and maize. It is caused by the negative-sense ssRNA virus wheat mosaic virus. Symptoms are similar to wheat streak mosaic virus, with leaf veins showing yellow flecks and streaks, followed by leaf margin purpling in maize. Depending on the timing of infection, stunting and death occur. Plants can be doubly infected with high plains virus and wheat streak mosaic virus. ==Vector and hosts== High plains virus is spread by wheat curl mites, ''Aceria tosichella'', which are small enough to be carried on air currents. Sandbur grass species are a known host for the wheat curl mite. High plains disease also may occur on barley, oats and rye, and on drooping brome ''Bromus tectorum'' and yellow foxtail ''Setaria pumila'' grasses.
