Sing. Using p301-bG1, PEG-mediated transformation of protoplast of L. edodes was studied. Mixed with PEG-purified plasmid DNA, the protoplasts of L. edodes were treated with PEG solution and cultured on CYM regeneration plate containing 40 mug/mL bialaphos. Bialaphos-resistant and GUS-positive transformants were obtained using this transformation system. Although the transformation efficiency was relatively low, the protocols release large expenses on expensive instrument and restriction enzymes, providing a simple and economical method for mushroom breeding at the molecular level.展开更多
