The secretory cells (PR cells) of the proventriculus of pgant4f02186/Df(2L)tim-02 larvae show disrupted morphology and secretion, are enlarged, and display loss of apical secretory components and secretory granules, compared to wild type.
Df(2L)tim-02/Pgant4f02186 is rescued by Pgant4UAS.cZa
Pgant4f02186 is rescued by Pgant4UAS.cZa/Scer\GAL4unspecified
Df(2L)tim-02/Pgant4f02186 is not rescued by Pgant4m2.UAS
Pgant4f02186 is not rescued by Scer\GAL4unspecified/Pgant4m2.UAS
Expression of pgant4Scer\UAS.cZa, but not pgant4m4.Scer\UAS, rescues the aberrant secretory apparatus structure and defective secretion seen in the PR cells of the proventriculus of pgant4 mutant larvae.
