The protoplast formation and regeneration of Morchella crassipes were studied. The optimum conditions for protoplast formation were determined. In details, the enzymolysis system consisted of 4% snailase, 5% lywallzyme and 4% ellulase. And 0.6 mol/L KCl phosphate buffer (pH 6.98) was used. The enzymolysis was conducted at 30℃ for 4 h. The age of cells for protoplast preparation was 56 h. The protoplast yield reached 5.3×104 cells/mg. On the PSA (potato sucrose agar) medium contenting 0.3 mol/L KCl and 0.3 mol/L inositol, the regeneration rate was 9%.
