title: Rapid mitochondrial probes for analysis of polymorphisms in Fusarium oxysporum special forms.
abstract: A method is described for the production of simple mitochondrial DNA probes from filamentous fungi for the partial characterization of mitochondrial DNA without the need for cloning, gradient centrifugation or PCR amplification. A probe (P449) consisting of a 3.38 kb mitochondrial fragment from an isolate of Fusarium oxysporum special form cubense was used to determine RFLPs in restriction digests of total DNA from 28 isolates of F. oxysporum from a variety of hosts and locations. The probe showed mtDNA polymorphisms within and between different special forms.
