Transformation of the edible basidiomycete Lentinus edodes by restriction enzyme-mediated integration of plasmid DNA.
We have used the restriction enzyme-mediated DNA integration (REMI) method to establish a transformation system in Lentinus edodes using the recombinant plasmid pLC1-hph, which contains the L. edodes transcriptional signals and an Escherichia coli hygromycin B phosphotransferase gene. Protoplasts of L. edodes were treated by the PEG transformation mixture containing 50 units of SalI, which clea...
متن کاملTransformation of Monascus purpureus to hygromycin B resistance with cosmid pMOcosX reduces fertility
∗ Corresponding author Albino strain KB20M1 of Monascus purpureus was genetically transformed to hygromycin B resistance with cosmid pMOcosX, using biolistic bombardment. Conidia and mycelial fragments were used as the recipient material and rupture disk strengths of 6.2 and 9.3 MPa each yielded a transformed isolate from five bombardments. Southern analysis suggested a single copy of the cosmi...
متن کاملTagging developmental genes in Dictyostelium by restriction enzyme-mediated integration of plasmid DNA.
Introduction of restriction enzyme along with linearized plasmid results in integration of plasmid DNA at genomic restriction sites in a high proportion of the resulting transformants. We have found that electroporating BamHI or EcoRI together with pyr5-6 plasmids cut with the same enzyme stimulates the efficiency of transformation in Dictyostelium discoideum more than 20-fold over the rate see...
متن کاملEnzymatic Basis of Hygromycin B Resistance in Escherichia coli
A plasmid conferring resistance to the aminocyclitol antibiotic hygromycin B was isolated from Escherichia coli. The gene conferring resistance to this drug was cloned in pBR322, and the gene was localized to a fragment of ca. 1,510 base pairs. Resistance to hygromycin B is determined by an aminocyclitol phosphotransferase that modifies hygromycin B and structurally related antibiotics. The spe...
متن کامل[Genotyping of hepatitis B virus by restriction enzyme analysis].
Hepatitis B is one of the most common infectious diseases in the world, and 350 million people have been estimated to be chronic hepatitis B virus carriers world-wide. Hepatitis B virus (HBV) has been classified into 8 genotypes (A-H) based on an intergroup divergence of 8% or more in the complete nucleotide sequence. Different genotypes of the hepatitis B virus may influence the clinical outco...
