Family: Poaceae Weed host
Anthoxanthum latent blanching virus (ALBV)
Taxonomic position
Genus: Hordeivirus Family: Virgaviridae
Geographical distribution
ALBV infection in plants of Anthoxanthum odoratum was first reported from Wales, UK (Catherall and Chamberlain 1980). The virus spreads in the UK (Edwards et al. 1989).
Symptoms and host(s)
The virus-infected sweet vernal grass plants express inconspicuous chlorotic stripes in leaves and are sometimes symptomless.
Transmission
The virus is mechanically sap-transmissible to graminaceous hosts. There is no known vector for this virus.
Virion properties and genome
The virions are rod-shaped, straight, with modal length of 20 × 110–150 nm diameter (Edwards et al. 1989). The genome consists of three positive-sense single-stranded RNAs and a “triple gene block” set of cell-to-cell movement proteins (Jackson et al. 2011; Adams et al. 2017).
