Abstract
We describe a transformation system for the ciliate Stylonychia mytilus. The neomycin resistance gene from Escherichia coli transposon Tn5, which codes for the enzyme phosphotransferase and confers resistance to the antibiotic G 418, was ligated into macronuclear `gene-size' DNA molecules. Using this recombinant DNA for transformation experiments we show that the gene is replicated and expressed in transformed cells.
Keywords: aminoglycoside G 418 resistance, gene-sized DNA
