Description

The Gr64a coding sequences have been replaced with sequence encoding a GAL4 driver.

(Fujii et al., 2015)

The Gr64a coding sequences have been replaced with sequence encoding a GAL4 driver. A single loxP site is also present downstream of the inserted driver sequence

      Reference

      Homozygous Gr64aGAL4 mutant flies exhibit a reduced proboscis extension response to fructose and maltose upon stimulation of the tarsal taste sensilla.

      (Fujii et al., 2015)

      In Gr64aGAL4 mutants, sweet taste 5b sensilla GRNs have significantly decreased responses to Maltose and Maltotriose, but not to the sweet chemicals Sucrose, Fructose, Trehalose, Glucose and Stachyose, as compared to heterozygous controls; of those chemicals, sweet taste 5v sensilla GRNs have only show significantly decreased response to Maltotriose.
