RESTRICTION-ENDONUCLEASE ANALYSIS OF MITOCHONDRIAL-DNA OF METARHIZIUM-ANISOPLIAE STRAINS

Mitochondrial DNAs from strains A4, A19, AL, E6, E9 and MT of Metarhiz ium anisopliae var. anisopliae were isolated and characterized by rest riction-endonucleases. The banding pattern obtained was the same for a ll strains investigated, indicating that their mtDNAs have the same mo lecular sizes (about 36 Kb) and the same restriction sites for the enz ymes used. Thus, the restriction pattern of the mtDNA of these strains may serve as a specific marker for the identification of the variety anisopliae or of subpopulations of this variety.
