Wheat is an economically important crop in Colorado and around the world with many plant disease problems. The Roberts lab focuses on diseases that can cause significant yield losses in Colorado wheat, including viral diseases (Wheat streak mosaic virus and Triticum mosaic virus, among others) and bacterial leaf streak (caused by Xanthomonas translucens pv. undulosa).  Our goal is to better understand plant immunity in wheat and to characterize the pathogens that exist in and around Colorado wheat fields.
