Variation in electrophoretic karyotype among Mexican isolates of Mycosphaerella fijiensis.

The article determines the electrophoretic karyotype of Mycosphaerella fijiensis using contour-clamped homogenous electric field gel electrophoresis. The highest variation in banding profiles was found in the chromosomes with sizes below 1.5 megabases pairs. The physical and genetic mapping of the fungus could lead to the development of new strategies for the control of black Sigatoka.
