The white-rot basidiomycete Coriolus versicolor secretes several enzymes that participate in the degradation of lignin and various persistent organic pollutants. In this study, we attempted to establish a genetic transformation system with a homogenous promoter sequence for driving the gene for antibiotic resistance. We succeeded in cloning the promoter sequence of the gene for glyceraldehyde-3-phosphate dehydrogenase (gpd), which is expressed at high levels in C. versicolor. The expression vector pT7GPTHPT was constructed, which included a gene for resistance to hygromycin B under control of the gpd promoter. The successful selection of transformants on medium that contained hygromycin B indicated that the system should be useful not only for the genetic transformation of C. versicolor, but also for the overproduction of useful fungal enzymes such as laccase and peroxidase.
