Comparison of covered kernel smut Sporisorium sorghi isolates from different geographic regions by isozyme analysis
Phytopathology 86 (11 suppl.), S58-S59
Abstract: Covered smut infected kernels were collected from Kansas and five different regions of Africa. Single teliospore isolates obtained from these kernels were tested for the presence of 25 enzymes by starch gel electrophoresis. High levels of activity were detected for 11 enzymes. The isozyme banding patterns were considered to represent 11 genetic loci. Ten loci were monomorphic among all teliospores tested. One isolate from Senegal had a different isozyme banding pattern from other isolates on the only polymorphic locus found. There is a high degree of intraspecific relatedness in Sporisorium sorghi.
