Virus infection in an endangered grassland habitat

Abstract : The Barley and Cereal yellow dwarf virus (B/CYDV) species complex includes some of the most economically important disease-causing agents of small grain cereal crops. BYDV plays an important role in the competitive dynamics of native and invasive grasses in nonmanaged systems. B/CYDV are known to infect over 150 Poaceae species, and BYDV was recently found to infect the invasive species Ventenata dubia in grassland habitats. The Palouse region of northern Idaho and eastern Washington in the USA is one of the most productive wheat-growing regions of the world, but little is known about viral prevalence in grassland habitats of the region. In order to manage and conserve endangered grasslands a better understanding of the interactions among members of an ecological community, including pathogens, is required. The objectives of this study were to determine the prevalence of B/CYDV among grass hosts in endangered Palouse Prairie remnants and Conservation Reserve Program (CRP) lands, identify B/CYDV species present in the region, and examine the factors that influence virus prevalence.
