  • P-element induced lethal mutations on the X or third chromosomes were first screened for pupal lethality. A salivary gland-specific GFP marker was then crossed into these pupal lethals and alleles were selected that displayed a persistent salivary gland (PSG) phenotype. The numbers corresponding to each class are listed.

  • a One P-element mutation could not be mapped to a gene because it resides within a yoyo transposable element.
