Mating Types of Phaeosphaeria nodorum (anamorph Stagonospora nodorum) from Central Asia

The distribution was examined of the mating type idiomorphs (MAT-1 and -2) of Phaeosphaeria (anamorph Stagonospora) nodorum using DNA from 49 isolates collected from commercial and experimental fields in 2003 and 2004 in Central Asia. MAT-1 and -2 isolates were present in the Kazakh and Russian origins of P. nodorum, but no MAT-2 isolates were found in Tajikistan. The possibility of a skewed Tajik population cannot be excluded, considering that the sampled region in Tajikistan was geographically isolated from Kazakhstan and Russia
