Efficient transformation of the medicinal mushroomGanoderma lucidum

Efficient transformation of the medicinal mushroomGanoderma lucidum Ganoderma lucidum is a well-known and important medicinal mushroom, but its genetic modification has not been reported. We developed an efficient procedure for isolation and regeneration of protoplasts fromG. lucidum. To construct a vector for high-level expression of heterologous genes inG. lucidum, the 1.4-kb regulatory region of the glyceraldehyde-3-phosphate dehydrogenase gene (GPD) was isolated from the genomic DNA ofLentinus edodes, and theGPD promoter was fused to the β-glucuronidase (GUS) and bialaphos resistance (bar) genes. Using the resulting construct, p301-bG1, an efficient transformation system based on electroporation was established forG. lucidum. GUS expression was observed among transformants conferring bialaphos resistance, indicating that theL. edodes GPD promoter can be used for expression of exogenous genes inG. lucidum. We also studied green fluorescent protein (GFP) as another reporter for transformation ofG. lucidum. TheL. edodes GPD promoter was fused respectively to theGFP andbar genes, and the resulting construct, p301-bg, was introduced intoG. lucidum. StableGFP expression in transformants was detectable by fluorescence microscopy, suggesting the suitability ofGFP as a reporter system in transformation of this mushroom. This is the first report of an efficient transformation system forG. lucidum using different reporters, paving the way for genetic modification of this famous medicinal mushroom. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Plant Molecular Biology Reporter Springer Journals

Abstract

Ganoderma lucidum is a well-known and important medicinal mushroom, but its genetic modification has not been reported. We developed an efficient procedure for isolation and regeneration of protoplasts fromG. lucidum. To construct a vector for high-level expression of heterologous genes inG. lucidum, the 1.4-kb regulatory region of the glyceraldehyde-3-phosphate dehydrogenase gene (GPD) was isolated from the genomic DNA ofLentinus edodes, and theGPD promoter was fused to the β-glucuronidase (GUS) and bialaphos resistance (bar) genes. Using the resulting construct, p301-bG1, an efficient transformation system based on electroporation was established forG. lucidum. GUS expression was observed among transformants conferring bialaphos resistance, indicating that theL. edodes GPD promoter can be used for expression of exogenous genes inG. lucidum. We also studied green fluorescent protein (GFP) as another reporter for transformation ofG. lucidum. TheL. edodes GPD promoter was fused respectively to theGFP andbar genes, and the resulting construct, p301-bg, was introduced intoG. lucidum. StableGFP expression in transformants was detectable by fluorescence microscopy, suggesting the suitability ofGFP as a reporter system in transformation of this mushroom. This is the first report of an efficient transformation system forG. lucidum using different reporters, paving the way for genetic modification of this famous medicinal mushroom.
