The sequences encoding the C-terminus of pnr-β are replaced by the sequences carrying the frame-shift deletion characteristic of pnrVX1.
visible, with Scer\GAL4pnr-MD237
dorsocentral bristle, with Scer\GAL4pnr-MD237
Over-expression of pnrVX6 using Scer\GAL4pnr-MD237 leads to the loss of dorsocentral bristles.
