Expression of O-fut1^Scer\UAS.cOa under the control of Scer\GAL4^ap-md544 results in the production of extra microchaetae. Macrochaeta number is not affected.

Flies expressing O-fut1^Scer\UAS.cOa under the control of Scer\GAL4^ptc-559.1 can have a mild wing vein phenotype. When O-fut1^Scer\UAS.cOa and O-fut1^{dsRNA.Scer\UAS} are coexpressed under the control of Scer\GAL4^ptc-559.1, their phenotypes are mutually suppressed, resulting in wild-type wings. Flies expressing O-fut1^Scer\UAS.cOa under the control of Scer\GAL4^sd-SG29.1 show wing loss and thickened vein phenotypes. Flies expressing O-fut1^Scer\UAS.cOa under the control of Scer\GAL4^ap-md544 have increased bristle density on the notum.
