Mating-Type Analysis in <i>Diaporthe</i> Isolates from Soybean in Central Europe.

ABSTRACT: Species of the genus Diaporthe have a mating-type system with the two mating types MAT1-1 and MAT1-2, like other ascomycetes. They can either be heterothallic, which means that any isolate only possesses one of the two mating types and needs a mating partner for sexual reproduction, or homothallic, which means that they possess both mating types and are self-fertile. For several Diaporthe species, no sexual reproduction has been observed so far. Using PCR with primers specific to the defining genes MAT1-1-1 and MAT1-2-1, we determined the mating types of 33 isolates of Diaporthe caulivora, D. eres, D. longicolla, and D. novem from central Europe. In addition, we partially sequenced the mating-type genes of 25 isolates. We found that d
