Fig. 5. Overexpression of SGG in mushroom bodies and olfactory receptor neurons does not alter olfactory habituation. (A) Expression of either UAS-SGG.S9A or UAS-SGG10 in the mushroom bodies with the GAL4 drivers 17D, c747, and 201Y. 17d expression is restricted to the a/b lobes of the mushroom bodies, 201Y is expressed in the g-lobes (1), and c747 is expressed strongly in all mushroom body lobes and less strongly in other brain regions (2). (B) Overexpression of UAS-SGG.S9A in olfactory receptor neurons does not affect olfactory habituation. The GAL4 driver Or83b is expressed in 70-80% of olfactory receptor neurons; Or22a is expressed in a more restricted pattern (3). One-way ANOVA found no effect of genotype (P = 0.27).
