Fig. 5. Effects of suppression of citb018a09 function with specific morpholino. (A-C) Morphology of larvae injected with control lacZ morpholino (A), or the first (B) or second (C) forms of citb018a09-specific morpholino. (D-I) Whole-mount in situ hybridization showing the expression of a marker gene for the whole nervous system, Ci-ETR (D,E), and two genes involved in the function of the photosensory organ, Ci-opsin3 (F,G) and Ci-arr (H,I). (D,F,H) Control embryos. (E,G,I) Embryos injected with the first form of citb018a09-specific morpholino. See text for details. Scale bar: 50 µm.
