The expression of shtd^GD14150 under the control of Scer\GAL4^ey.PU leads to eye defect, including a mild decrease in eye size, severe eye morphology and polarity defects, and the frequent formation of ectopic structures within the eye field that resemble naked head cuticles or antennae (indicative of a complete loss or a conversion of cell fate), as compared to controls; this expression strongly inhibits both morphogenetic furrow progression (particularly evident in the lateral margin regions) and retinal differentiation in the third instar larval eye disc, without affecting the disc size, as compared to controls.

The expression under the control of Scer\GAL4^GMR.PU does not lead to any obvious eye defects, as compared to controls.

Expression under the control of Scer\GAL4¹⁴⁰⁷ results in loss of neuroblasts in the larval brain associated with decreased size of the remaining neuroblasts.

Expression under the control of Scer\GAL4¹⁴⁰⁷ results in a reduction in the average size of neuroblasts together with shorter neuroblast lineages (less daughter cells per neuroblast) in the larval brain compared to controls.

Expression under the control of Scer\GAL4^pnr-MD237 results in bristle morphology defects on the notum in 10-20% of the Scer\GAL4^pnr-MD237 expression domain.

Expression under the control of Scer\GAL4^pnr-MD237 results in the absence of 80-90% of the Scer\GAL4^pnr-MD237-expressing area of the notum.
