Fig. 5. Rescue of EcR-B mutant phenotype by transgenic expression of EcR-B1 or EcR-B2-isoform. (A) EcR-B mutant control (EcR³¹/EcR⁹⁹). (B) EcR³¹/EcR⁹⁹; UAS-EcR-B1/Crz-gal4. (C) EcR³¹/EcR⁹⁹; UAS-EcR-B2/Crz-gal4. The histograms indicate percentages of the CNSs showing no cell death (open bar), partial (gray bar), or complete death (black bar). As described in the text, the CNSs were grouped into `E' (Early), `I' (Intermediate), or `L' (Late), depending on their developmental status. Numbers of tissues examined in each category are noted on the right of each bar (N), and mean numbers of vCrz neurons (± s.d.) are in parentheses. The CNSs belonging to the `E' group were not found in the EcR-B2 rescue group. Representative images taken from the `I' group are shown in the left. Scale bar: 100 µm.
