Rescue of ch organs in ato¹ mutant embryos by UAS-ato/sc chimeric genes. (A and F) Wild-type embryo contains five ch neurons in the lateral region (lch5, marked by the brackets in A–E) in each abdominal hemisegment. Most of the ch neurons are eliminated in ato¹ mutant embryo (B and G). The lch5 of ato¹ embryos in alternate segments were rescued by h-GAL4; UAS-ato (C and H) and by h-GAL4; UAS-sc-b(ato) (E and J) combinations, but not by h-GAL4; UAS-sc (D and I). In F–J, the first four abdominal hemisegments of the embryos in A–E are shown, respectively.
