In order to confirm the presence of putative glucoamylase gene in Tricholoma matsutake genome, the genomic DNA was prepared from T. matsutake NBRC30773 strain and was used as template to clone the glucoamylases gene (TmGlu1). We obtained the nucleotide sequence of TmGlu1 and its franking region. The coding region (from ATG to stop codon) is 2,186 bp. The locations of exons and introns were determined from the nucleotide sequences of 3’- and 5’-RACE PCR and RT- PCR products. On the other hand, to investigate the relationship between composition of medium and glucoamylase expression, we checked the expression level of glucoamylase gene by realtime reverse transcription PCR and measurement of glucoamylase enzyme activity. It was found that enzyme activity of glucoamylase was very low in different medium. Expression of glucoamylases gene appeared to not be affected by different carbon source.
