Electrophoretic molecular karyotype of the dermatophyte Trichophyton rubrum

The electrophoretic karyotype of the dermatophyte Trichophyton rubrum was established using contour-clamped homogeneous electric field (CHEF) gel electrophoresis. Five chromosomal bands of approximately 3.0 to 5.8 megabase pairs (Mbp) each were observed and together indicated that 22.05 Mbp of the total genome are organized as chromosomal macromolecules. In addition to establishing the number and size of T. rubrum chromosomes, these results open perspectives for the construction of chromosome-specific libraries and for the physical mapping of genes of interest, thus permitting future gene link...
