Figure 3. ten-a deficiency line ten-a^#900 and down-regulated ten-a expression by RNAi caused FB and EB defects.

(A, B) ten-a^#900 showed a FB and EB defect. (C–H) cbd ^KS171, cbd ²²⁵⁴ and cbd ^KS96 could not complement the FB and EB defect of ten-a^#900. (I–L) Both the FB and the EB were destroyed when ten-a was down-regulated by driving expression of UAS-ten-a ^RNAi with tub-Gal4. (M–N) Both the FB and the EB were destroyed when ten-a was down-regulated by driving expression of UAS-ten-a ^RNAi with pan-neuronal elav-Gal4. (O–P) Both the FB and the EB were normal when ten-a was down-regulated by driving expression of UAS-ten-a ^RNAi with pan-glial repo-Gal4. Scale bar, 25 µm. Arrows indicate the central complex defect.
