The grass Agropyron tsukushiense var. transiens is native to Far East Asia, and Hordeum compressum is native to southern South America. They were found to be susceptible to all the races that they were tested to of the following: loose smut of wheat (Ustilago tritici): loose, covered, and false loose smut of barley (U. nuda, U. hordei, and U. nigra); loose and covered smut of oats (U. avenae and U. kolleri); and head smut of grasses (U. bullata). The two grasses are the first known common hosts for these smuts and will be used to study the relationships between these pathogens.
