UASt regulatory sequences drive expression of the Ater\BSD, which encodes a blasticidin S deaminase and confers resistance to blasticidin.
chemical resistant | larval stage, with Scer\GAL4Act5C.PU
Addition of blasticidin to standard fly food (150 micrograms/ml final concentration) is observed to kill all control larvae but not those expressing Ater\BSDUAS.cLa driven by Scer\GAL4Act5C.PU.
