Improvement of the Transformation Efficiency of Flammulina velutipes Fv-1 Using the Glyceraldehyde-3-phosphate Dehydrogenase Gene Promoter

抄録

To improve the expression level of heterologous genes in Flammulina velutipes Fv-1, we constructed new vectors having glyceraldehydes-3-phosphate dehydrogenase (gpd) gene promoter to control the expression of target genes. When the hygromycin B phosphotransferase (hph) gene from Escherichia coli was controlled by the gpd promoter, transformation efficiency was 3-fold higher than the case of that controlled by the tryptophan synthetase gene (trp1) promoter.
