A cDNA library was constructed using mRNA from the cells of 7-day-old cultures of Flammulina velutipes after induction of fruiting treatment. A cDNA clone, FVFD16 (Flammulina velutipes fruiting body differentiation), was selected by differential screening. The expression property of the FVFD16 gene was examined by Northern blot analysis. FVFD16 represents mRNA that is specifically expressed during differentiation of fruit bodies. The conspicuous accumulation of the FVFD16 mRNA was detected in 4-day-old and 1-day-old cultures. The nucleotide sequence of the FVFD16 gene was determined and the mRNA contained an open reading frame that encoded a putative protein of 128 amino acid residues (13.5 kDa).
