Abstract
Fifteen isolates of F. avenaceum were pathogenic to oat seedlings, irrespective of host plant from which they had originally been isolated. Pathogenicity was correlated to the activity of cell wall-bound .beta.-glucosidase and .alpha.-arabinosidase of the mycelium. The observed enzymatic hydrolysis of avenacin to the biologically inactive aglycone avenamin in infected oat roots by all fungal isolates demonstrates the species-specificity of this inactivation mechanism and explains also the lack of oat-specific races of the fungus. One isolate of F. avenaceum retained its pathogenicity despite continuous subculture on nutrient agar for 27 yr.
