a Prior to the revised nomenclature of mating type genes, the MAT loci of Magnaporthe spp. were arbitrarily named Mat1-2 and Mat1-1. While these names have since been changed to comply with the naming system, the pheromone gene names still reflect the original MAT gene names. b In homothallic fungi, the mating type genes are all found within a single genome. Thus, it is not necessary to classify the locus as MAT1-1 or MAT1-2. However, these species do still harbour MAT genes with homology to those found in heterothallic species. c T. reesei harbours the h-type pheromone in place of the a-factor pheromone found in many other species. Furthermore, the two pheromones of T. reesei are not expressed in a mating-type dependant manner. This is covered in the section regarding pheromones.
