The secretory cells (PR cells) of the proventriculus of larvae expressing pgant4dsRNA.Scer\UAS.WIZ show disrupted morphology and secretion, are enlarged, and display loss of apical secretory components and secretory granules, compared to wild type.
Expression of pgant4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4αTub84B.PL results in complete loss of viability.
Expression of pgant4dsRNA.Scer\UAS.WIZ in the digestive system under the control of Scer\GAL4c135 results in almost complete lethality.
Expression of pgant4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4Bx-MS1096 does not result in wing blistering.
Pgant4RNAi.UAS.WIZ, Scer\GAL4path-c135 has embryonic/larval proventriculus outer layer phenotype, suppressible by Tango1UAS.cZa, Scer\GAL4path-c135
Pgant4RNAi.UAS.WIZ, Scer\GAL4path-c135 has secretory granule phenotype, suppressible by Tango1UAS.cZa, Scer\GAL4path-c135
Pgant4RNAi.UAS.WIZ, Scer\GAL4path-c135 has embryonic/larval proventriculus outer layer phenotype, suppressible by Fur2KK104000, Scer\GAL4path-c135
Pgant4RNAi.UAS.WIZ, Scer\GAL4path-c135 has secretory granule phenotype, suppressible by Fur2KK104000, Scer\GAL4path-c135
Pgant4RNAi.UAS.WIZ, Scer\GAL4path-c135 has embryonic/larval proventriculus outer layer phenotype, non-suppressible by Fur1GD12608, Scer\GAL4path-c135
Pgant4RNAi.UAS.WIZ, Scer\GAL4path-c135 has secretory granule phenotype, non-suppressible by Fur1GD12608, Scer\GAL4path-c135
Expression of Tango1Scer\UAS.cZa in PR cells via Scer\GAL4c135 rescues the aberrant secretory apparatus structure and defective secretion seen in the PR cells of the proventriculus of pgant4dsRNA.Scer\UAS.WIZ-expressing larvae.
Expression of Fur2KK104000, but not Fur1GD12608, in PR cells via Scer\GAL4c135 rescues the aberrant secretory apparatus structure and defective secretion seen in the PR cells of the proventriculus of pgant4dsRNA.Scer\UAS.WIZ-expressing larvae.
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.
