Microsatellite loci are increasingly used as markers in the human, animal and plant genomes. Being highly mutable, microsatellite regions are able to differentiate between related taxa, even at the level of individual isolates in a single species. Studies on mushroom population structure, gene flow and dispersal between natural and cultivated species have become central in breeding programmes and the knowledge of new polymorphic, codominant markers will be a promising avenue to exploit wild genetic resources. The molecular phylogeny in 50 different commercial cultivated strains of Pleurotus eryngii using PCR amplification with URP primers and mitochondrial microsatellite primer was studed. The sizes of the polymorphic fragments obtained were in the range of 200 to 2000 bp. RAPD analysis techniques were able to detect genetic variation among the tested strains. With these isolated PCR amplification with URP primers we intend to analyse the population structure of the P. eryngii species complex and investigate the structure of the basidiomycete genome which deserves. A few single-locus microsatellite markers have been isolated in Pleurotus eryngii and Pleurotus ferulae. This technique is useful in those species where microsatellite loci are rare in the mitochondria.
