Description

Deletion of the Obp57e 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 Obp57e.

      Reference

      Obp57eKO males and females avoid hexanoic acid (HA) in an olfactory trap assay.

      Obp57eKO females seem to prefer lower concentrations of HA than control flies in an oviposition site-preference assay, although the difference is not statistically significant.

      Obp57eKO females prefer higher concentrations of octanoic acid than control flies in an oviposition site-preference assay.

      Obp57eKO females prefer concentrations of acetic acid and butyric acid similar to those preferred by control flies in an oviposition site-preference assay.
