Description

The Gr64c coding sequence has been replaced with sequence encoding a lexA::VP16 driver.

(Fujii et al., 2015)

The Gr64c coding sequence has been replaced with sequence encoding a lexA::VP16 driver. A single loxP site is also present downstream of the inserted driver sequence.

      Reference

      Homozygous Gr64cLEXA mutant flies exhibit a reduced proboscis extension response to arabinose upon stimulation of the labial and tarsal taste sensilla. The responses to sucrose, maltose and glycerol are also reduced upon stimulation of the tarsal sensilla.
