Figure 5

arx-7(ok1118M+) displayed fewer growth cone filopodia than wild type. Fluorescent micrographs of posterior PQR neurites in representative samples of wild type (left column) and arx-7(ok1118M+) (right column) at 7 to 8 h after hatching. Arrows point to growth cones. For all micrographs, anterior is left, dorsal is up, and the scale bar = 2 μm.
