Protoplast transformation of glutamate-producing bacteria with plasmid DNA.
A method for polyethylene glycol-induced protoplast transformation of glutamate-producing bacteria with plasmid DNA was established. Protoplasts were prepared from cells grown in the presence of penicillin by treatment with lysozyme in a hypertonic medium. The concentration of penicillin during growth affected the efficiency of formation, regeneration, and polyethylene glycol-induced DNA uptake...
متن کاملPEG-mediated protoplast transformation with naked DNA.
1. Introduction Direct introduction of DNA into plant protoplasts facilitates a rapid analysis of transient gene expression, as well as the generation of stably transformed transgenic plants. Transient gene expression assays performed after DNA transformation permit a comparative analysis of cisacting regulatory sequences and their function in transcriptional control of plant genes by signaling...
متن کاملTransformation of Bacillus polymyxa with plasmid DNA.
A plasmid transformation system was developed for Bacillus polymyxa ATCC 12321 and derivatives of this strain. The method utilizes a penicillin-treated-cell technique to facilitate uptake of the plasmid DNA. Low-frequency transformation (10(-6) per recipient cell) of plasmids pC194, pBD64, and pBC16 was accomplished with this method. Selection for the transformants was accomplished on both hype...
متن کاملTransformation of Azotobacter vinelandii with plasmid DNA.
Azotobacter vinelandii cells can be transformed at high frequencies with the broad-host-range plasmids pRK2501, RSF1010, and pGSS15, using a modification of the procedure developed by Page and von Tigerstrom (J. Bacteriol. 139:1058-1061, 1979) for chromosomal DNA-mediated transformation. The frequency of transformation per microgram of plasmid DNA per viable cell with pRK2501 and pGSS15 was abo...
متن کاملConfirmation of protoplast fusion-derived linkages in Staphylococcus aureus by transformation with protoplast DNA.
Transformation provided definitive evidence for linkage between tyrB282::Tn551 ermB321 and omega (Chr::Tn551)34, and thus between the separate large linkage groups containing these markers, in Staphylococcus aureus NCTC 8325. Transformation also defined the chromosomal loci for the purC193::Tn551 and omega (Chr::Tn551)42 markers and the linkage of a tetracycline resistance marker (tet-3490) wit...
