Transformation of Pleurotus ostreatus PC9 with the mutated heterotrimeric G protein alpha subunit (Gα) gene resulted in higher laccase (Lac) activity and intracellular cyclic adenosine monophosphate (cAMP) concentrations as compared to those in wild-type PC9. The transformant also exhibited higher Lac activity than the wild type when cultured in a medium containing known Lac inducers CuSO4 and ferulic acid.
