The sequences encoding the DNA-binding domain (DBD) of pnr-β are replaced by the mutated sequences associated with pnrD4.
partially lethal - majority die, with Scer\GAL4pnr-MD237
visible, with Scer\GAL4pnr-MD237
dorsocentral bristle | increased number, with Scer\GAL4pnr-MD237
Over-expression of pnrD4.Scer\UAS.β using Scer\GAL4pnr-MD237 causes supernumerary dorsocentral bristles compared with wild-type. The viability of the flies expressing Scer\GAL4pnr-MD237>pnrD4.Scer\UAS.β is strongly reduced.
