title: The Use of Rare-Cutting Endonucleases in Electrophoretic Karyotyping of Fungal Genomes
abstract: A method for the fast and reliable restriction analysis of intact fungal chromosomes is presented. For this purpose rare-cutting restriction enzymes of pro- and eukaryotic origin were used. Restriction fragments were separated on pulsed-field gels. Complete inactivation of proteinases remaining from chromosome preparations was crucial in this attempt. Rare-cutting restriction enzymes were employed to demonstrate the applicability of this procedure to the analysis of complex fungal genomes. This includes the localization of genes on discrete chromosomal fragments,the identification of telomeric restriction fragments, and the analysis of fungal transformants.
