摘要: Isozyme and random amplified polymorphic DNA (RAPD) analyses have been used in combination with numerical taxonomy to study the taxonomic relationships among toxigenic species Fusarium acuminatum Ellis & Everh. sensu Gordon (subsp. subsp. armeniacum), sporotrichioides Sherb. tricinctum (Corda) Sacc. Eight enzymes, selected 23 enzyme systems tested initially for activity, resolution, consistent formation of bands, were isozyme analysis 75 strains. Both cluster grouping by average linkage method correspondence data set resulted an arrangement four taxa inconsistent their classical classification sections Gibbosum Sporotrichiella. Isolates F. more closely related than armeniacum. Correspondingly, armeniacum group was closer acumina...
