Adults expressing lin^GD1479 under the control of Scer\GAL4^elav.PLu (in the presence of Dcr-2^Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.

Expression of lin^GD1479 under the control of Scer\GAL4^bab1-Pgal4-2 in the leg results in distal tarsal segment fusion with t1 and differentiated sex comb bristles.

Expression of lin^GD1479 under the control of Scer\GAL4^bab1-Agal4-5 in the leg results in distal tarsal segment fusion with t1 and differentiated sex comb bristles.

Expression of lin^GD1479 under the control of Scer\GAL4^{rn-GAL4-DeltaS} in the leg results in distal tarsal segment fusion with t1 and differentiated sex comb bristles.

Expression of lin^GD1479 under the control of Scer\GAL4^Dll-md23 in the leg results in fusion of all the leg tarsal segments and the differentiation of sex comb bristles along the fused tarsus.

Expression of lin^GD1479 under the control of Scer\GAL4^dac-p7d23 along the intermediate region of the leg disc results in a severe decrease in the size of true segments, and loss of true joints. Bristled-cuticle is replaced with naked cuticle, and numerous vesicles form under the basal surface of the epithelium within the leg shaft.

Expression of lin^GD1479 under the control of Scer\GAL4^Dll-md23 in the antennae results in replacement of the AIII, the basal cylinder, and the arista with a poorly differentiated tubular structure.

Expression of lin^GD1479 under the control of Scer\GAL4^bab1-Pgal4-2 or Scer\GAL4^bab1-Agal4-5 in the antennae results in poor differentiation and expansion of the basal cylinder and aristal stalk.

Expression of lin^GD1479 under the control of Scer\GAL4^{rn-GAL4-DeltaS} in the antenna distorts the morphology of AIII and results in poor differentiation of the basal cylinder.

Expression under the control of Scer\GAL4^pnr-MD237 results in strong thorax closure defects.
