Posterior dorsocentral bristle neurons expressing sktlUAS.cHa
under the control of Scer\GAL4pnr-MD237
show a significantly decreased terminal arbor territory, as compared to controls.
When expression is driven by an elav
, no phenotype results. When expression is driven by Scer\GAL4da.G32
or a heat shock Scer\GAL4
, no phenotype results but early larval lethality results. When expression is driven by Scer\GAL4T80
third instar larval lethality results. Expression driven by Scer\GAL4dpp.blk1
causes no eye phenotype but ectopic bristles on the notum and wing blade. When expression is driven by Scer\GAL432B
ectopic bristles appear on the notum and wing blade. The ectopic bristles as well as the normal bristles show structural defects consistent with a role for sktl
in the cytoskeleton. All ectopic bristles are associated with socket cells.
