Comparison of the genomic DNA sequences of the tyrosinase 2 gene of G. frondosa. B and W represented nucleotide sequences of tyr2 from brown-colored wild-type monokaryotic strain IM-BM11-P21 and white-colored albino strain IM-WM1-25, respectively. Nucleotide sequences of tyr2 of albino strain (tyr2^−Δ25) that are identical with wild-type strain are indicated by dots. Codons that are containing nucleotide substitution with amino acid changing are underlined and amino acid residues are shown under the codon. The deletion mutation that was the possible main reason for deficiency of tyrosinase activity is boxed. Bold case letters indicate primer positions
