Expression driven by ScerGAL4Obp59a.PS colocalizes with Obp59a transcript.
ScerGAL4Obp59a.PS expression in the antenna is restricted to the second chamber of the sacculus. No expression is observed elsewhere in the adult head or body or in the three larval instars. ScerGAL4Obp59a.PS is expressed in non-neuronal cells of the hygrosensitive sensilla.
