Abstract
A plasmid construct containing the gene encoding tryptophan oxygenase (to) from Anopheles gambiae was introduced into green eye color mutants (ge) of the housefly, Musca domestica. Several variations in eye color were observed in 38.8% of the surviving G0 adults. The expression of A. gambiae to in the distantly related Diptera, housefly, implies conservation of the tryptophan oxygenase gene in the other Diptera and may be used for monitoring transformants as a marker in insects which have mutants homologous to Drosophila melanogaster vermilion.
