A family of genes encoding laccases has recently been described for the basidiomycete I-62 (CECT 20197). Transcript levels of genes lcc1, lcc2, and lcc3 were analyzed under four different culture conditions to study their expression patterns. Two of the laccase genes were clearly inducible by veratryl alcohol: the lcc1 gene is inducible in early stages of growth, and the lcc2 gene is also inducible but only when the organism reaches the stationary phase. Transcript levels for the third gene, lcc3, were uninduced by veratryl alcohol and repressed by glucose.
