Processing of olfactory information in the antennal lobes of insects and olfactory bulbs of vertebrates is modulated by centrifugal inputs that represent reinforcing events. Octopamine release by one such pathway in the honeybee antennal lobe modulates olfactory processing in relation to nectar (sucrose) reinforcement. To test more specifically what role(More)
rab3A is a small neuronal GTP-binding protein specifically localized to synaptic vesicles. Membrane-bound rab3A behaves like an intrinsic membrane protein in vitro, but reversibly dissociates from synaptic vesicles after exocytosis in vivo. Here we demonstrate that rab3A is attached to synaptic vesicle membranes by a carboxy-terminal Cys-X-Cys sequence that(More)
Previously, we generated P-element insert lines in Drosophila melanogaster with impaired olfactory behavior. One of these smell-impaired (smi) mutants, smi60E, contains a P[lArB] transposon in the second intron of the dsc1 gene near a nested gene encoding the L41 ribosomal protein. The dsc1 gene encodes an ion channel of unknown function homologous to the(More)
Most animals depend on olfaction for survival and procreation. Odor-guided behavior is a quantitative trait, with phenotypic variation due to multiple segregating quantitative trait loci (QTL). Despite its profound biological importance, the genetic basis of naturally occurring variation in olfactory behavior remains unexplored. Here, we mapped a single(More)
