- Abstract
Pleurotus pulmonarius is a tetrapolarity heterothallic fungus, but the structure of its mating loci has not yet been resolved, causing troubles in breeding of the fungus. In this study, the genome of P. pulmonarius was sequenced by second generation sequencing technology, and mating type loci of progeny of the wild variety X1 were searched by bioinformatics method. The results showed that A mating loci of P. pulmonarius were specific and the structure of A mating loci in two protoplast mononucleated strains (X1-1 and X1-15) was quite different. X1-1 contained a pair of conservative HD1 and HD2 genes, while X1-15 contained two additional HD2 genes and one HD1 gene in addition to a pair of HD1 and HD2 genes. The B mating type locus of P. pulmonarius is similar to that of other basidiomycetes, containing eight pheromone receptor genes and one pheromone precursor gene. The specific mating-locus structure of P. pulmonarius revealed in this paper provides a theoretical basis for later genetic study and breeding of the fungus.
