P{EP}sanoGE12233 is inserted 147bp downstream of the sano transcription start site.
Homozygous sanoGE12233 larvae show a response to low-salt concentrations (at 10 and 50mM NaCl) similar to that observed in wild-type or heterozygous larvae.
At 100mM NaCl, sanoGE12233 mutant larvae display an attractive response to salt, whereas wild-type larvae show no preference.
At high salt concentrations (200, 300, and 500mM NaCl), sanoGE12233 mutant larvae display strong defects in their aversion to NaCl.
sanoGE12233 mutant larvae, with as wild-type, are attracted by 100mM sucrose and repelled by 10mM caffeine or 10mM quinine.
sanoGE12233 is rescued by Scer\GAL4sano/sanoUAS.cAa
