Polymerase chain reaction amplification of 33 A. alternata isolates from Datong with the two mating type-specific primers.
The primers amplify a ~661 bp unique fragment from isolates carrying MAT1-1 idiomorph and a 494 bp unique fragment from isolates carrying MAT1-2 idiomorph. The first panel is a 100-bp size ladder.
