Description

Deletion of the Obp57d gene. The w+* marker gene that was introduced as part of the original mutagenic event has been removed using P1cre recombinase, leaving only a single 34bp loxP sequence in place of Obp57d.

      Reference

      Obp57dKO males and females avoid hexanoic acid (HA) in an olfactory trap assay.

      Obp57dKO females prefer higher concentrations of octanoic acid than control flies in an oviposition site-preference assay.

      Obp57dKO females prefer concentrations of acetic acid and butyric acid similar to those preferred by control flies in an oviposition site-preference assay.
