Transformation of Phycomyces with a bacterial gene for kanamycin resistance.
Phycomyces protoplasts transformed with a plasmid containing the bacterial gene for kanamycin resistance grow in the presence of G418, a kanamycin analogue. The plasmid also contains a Phycomyces DNA sequence that supports autonomous replication in yeast. We obtained about 250 transformants per microgram DNA or one per 5000 viable protoplasts. The transformant phenotype is retained under selective conditions and lost in the majority of the vegetative spores. Recovered plasmids and Southern analysis indicate that the plasmid probably replicates autonomously in Phycomyces.
