The mating-type genes control formation of the dikaryon from two haploid strains. These genes are now used in mating-type-assisted breeding programs for economically important mushrooms, especially the oyster mushroom, Pleurotus ostreatus, aiming at high-yield and high-quality standard mushroom production. However, it improves the breeding program when the breeder is able to quickly identify compatible strains in a given set of progeny. The two mating factors with their mating-type loci are used as markers for breeding and have been incorporated in a chromosome mapping investigation. The linkage maps include not only genetic markers such as the mating types that can be cored, but also molecular markers such as PCR-assisted approaches, e.g. RAPD analyses, or RFLP markers. Once mating-type genes within progeny may be more easily identified by the use of PCR-directed cloning of partial mating-type genes. We analyzed homeodomain (HD1 and HD2) and pheromone receptor(rcb1, 2 and 3) genes as molecular markers for breeding using mating type A and B of Pleurotus eryngii and Pleurotus ferulae by direct PCR.
