Abstract

Both A and A mating types of and formed oospores by selfing when they were paired with different mating types on opposite sides of polycarbonate membranes. The selfing of one mating type in the presence of the other mating type demonstrates the production of diffusible substances like plant hormones as found in related fungi. Young cultures and A isolates were better hormone producers, whereas old cultures and A isolates were more responsive to hormones in both intra- and interspecific pairings. The polycarbonate membrane method should facilitate identification and genetic studies of heterothallic species of .
