Adult flies expressing BG4dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 show a reduced survival rate compared to control flies after bacterial (E.carotovora) infection.
The immune response to infection with the Gram-negative bacteria P.carotovorum, as determined by induction of Dpt, is reduced when BG4dsRNA.Scer\UAS expression is driven in the fat body by Scer\GAL4c564.
When BG4dsRNA.Scer\UAS is driven by Scer\GAL4yolk, mutant animals are highly susceptible to Gram-negative bacterial infection, exhibiting a dramatic loss of survival rate after infection, with almost all animals dying within 4 days. However, mutants appear resistant to fungal infection. Expression of BG4dsRNA.Scer\UAS when driven by Scer\GAL4da.G32 shows no detectable developmental defects.
FaddRNAi.UAS, Scer\GAL4da.G32 has abnormal immune response phenotype, enhanceable by MP1RNAi.UAS.WIZ, Scer\GAL4da.G32
FaddRNAi.UAS, Scer\GAL4da.G32 has abnormal immune response phenotype, enhanceable by Sp7RNAi.UAS.WIZ, Scer\GAL4da.G32
FaddRNAi.UAS, Scer\GAL4Switch1.106 is a suppressor of abnormal immune response phenotype of PGRP-LEUAS.Tag:FLAG, Scer\GAL4Switch1.106
Simultaneous expression of BG4dsRNA.Scer\UAS driven by Scer\GAL4S106-GS significantly suppresses the increased pathogen resistance phenotype of PGRP-LEScer\UAS.T:Zzzz\FLAG-expressing flies.
Co-expression of either MP1dsRNA.Scer\UAS.WIZ or Sp7dsRNA.Scer\UAS.WIZ results in a moderate further decrease in the survival rate of flies expressing BG4dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 after bacterial (E.carotovora) infection.
Transcription from the P{UAS-BG4-dsRNA} construct should produce BG4 dsRNA, resulting in dsRNA interference (RNAi) of the BG4 gene.
