Polytene chromosomes normal.
Insertion of 7.6kb DNA, with no obvious similarity to known transposable elements, between positions -1.7 and -0.8.
st1 and st1/Df(3L)ED4606 mutant adults show a significant and progressive decrease in climbing ability, as compared to controls. Unlike controls, both these mutant adults show a significant and progressive decrease in the number of PPL1 neurons (decreases observed from from day 3 to days 18 and 21, respectively) when raised at 29[o], but not at 25[o]C, as compared to controls.
Mutant flies have significantly fewer synaptic vesicles in the terminals of the photoreceptor cells R1-R6 in the lamina. However, in contrast to the absolute numbers of synaptic vesicles, the profile density is not significantly different from wild type. There is no significant difference in the normalized number of single-headed capitate projection profiles in the photoreceptor terminals, but the number of multiple-headed capitate projection profiles is higher than normal.
Male homozygous st1 flies are undistinguishable from wild-type flies in their sensitivity to enflurane. This effect is true whether enflurane resistance is measured in regular light or red light.
Eye colour: light yellow, with st14.
Malpighian tubule colour: pale yellow.
Eye color autonomous in larval optic discs transplanted into wild-type hosts.
st1 has locomotor behavior defective | adult stage | progressive phenotype, non-enhanceable by cn1
st1 has short lived phenotype, non-enhanceable by cn1
st1 has decreased cell number | adult stage | progressive | heat sensitive phenotype, suppressible by cn1
st1 is a non-enhancer of locomotor behavior defective | adult stage | progressive phenotype of cn1
st1 is a non-enhancer of chemical resistant | dominant | male phenotype of bw1
st1 is a non-suppressor of chemical resistant | dominant | male phenotype of bw1
lz51d, st1 has eye color defective phenotype
st1 has dopaminergic PPL1 neuron | progressive | heat sensitive phenotype, suppressible by cn1
lz51d, st1 has pigment cell phenotype
The increased resistance of bw1 homozygous males to enflurane is not enhanced or suppressed by st1/st1. bw1/+, st1/+ males from bw1, st1 homozygous mothers show increased resistance to halothane when tested under red light but not when tested under white light. A maternal effect is necessary for this phenotype as it is not seen in bw1/+, st1/+ males from bw1, st1 homozygous fathers.
Eye colour: white with lz51d.
st1 is partially rescued by Scer\GAL4ple.PF/stUAS.Venus
