Isozyme and general protein patterns of Armillaria spp. collected from the boreal mixedwood forest of Ontario

Isolates of four North American biological species of Armillaria, I (A. ostoyae), III, V, and VII (A. lutea), that occur in the boreal mixedwood forest of Ontario were differentiated by their esterase isozyme patterns and total protein profiles. Within biological species I, there are two types of esterase patterns that correspond to the genotypically distinct clones observed in isolates from the same geographic area. In addition, isolates of biological species I from different geographic areas showed differences in their esterase patterns. The general protein patterns of four biological species of Armillaria isolated from maple also showed the distinct pattern of each intersterility group.
