TABLE 1.
Summary of pilot screen for persistent larval salivary glands
| Lethals (total) | Pupal lethals | PSG alleles | PSG loci | |
|---|---|---|---|---|
| X chromosome | 398 | 94 | 9a | 3 |
| Third chromosome | 467 | 131 | 2 | 2 |
| Total | 865 | 225 | 11 | 5 |
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.
