Figure 8.

atk mutant larvae show a significantly reduced response to sucrose. Response index for election between 1% agarose and 1% agarose + 0.5 M sucrose. atk³³ null mutants show defects in chemosensation. atk²³ hypomorphs and Uhg8^EY07139 homozygous larvae, which keep atk expression in chemosensory organs, do not show defects. Therefore, ATK seems to be required for chemosensation, although an effect of additional genes deleted by the atk³³ deficiency cannot be ruled out. Error bars indicate SEM. Significant difference with respect to wild type was established by Bonferroni-corrected t-test. ***P < 0.001.
