US Patent 7253333 Drosophila strain carrying bradeion gene(s) transferred thereinto

Provided is a special Drosophila strain having a Bradeion gene artificially incorporated therein to exclusively express the gene in the compound eyes and thus to exhibit rough eye. The Drosophila strain has the following properties:(a) a human-derived Bradeion gene has been transferred in the strain to express the human-derived protein Bradeion in the compound eyes from the developmental period;(b) the compound eyes show morphological abnormality due to the expression of Bradeion; and(c) the morphological abnormality occurring in the compound eyes is multiplied according to the number of transferred Bradeion genes.
