Fig. 2. Sensory behaviors of Rfx mutants. Three different assays were performed and the corresponding data are plotted. Each point is the response index obtained with 30 larvae per individual test. Dots represent Rfx²⁵³/TM6B, Tb larvae; stars indicate Rfx⁴⁹/Rfx²⁵³ larvae; diamonds indicate Rfx⁴⁹/Rfx⁴⁹ larvae. (A) Data for olfactory assays to attractive (butanol), repulsive (n-octyl-acetate) or non odorant (NaCl) control substances. (B) Data for chemosensory assays to high NaCl concentrations or control NaCl concentrations. (C) The result of a typical phototaxy experiment with Rfx⁴⁹/TM6B control larvae on top and Rfx⁴⁹/Rfx²⁵³ mutant larvae on the bottom. The plot shows the quantification of phototaxis assay data.
