Description
Environmental temperature directly affects the concentration of chemicals in the gas phase. Therefore, if the olfactory system does not adapt to environmental conditions may provide inadequate information about distance to or direction of odor sources. Previous reports in Drosophila melanogaster show that temperature induces changes in olfactory sensitivity in complete individuals. Electrophysiological analysis demonstrates that these changes initiate at the olfactory receptor organs. In this experiment we try to identify particular genes responsible for olfactory adaptation to increasing temperatures using receptor organs of Drosophila after exposure to high temperatures. With this aim, wild-type Canton-S flies were subjected to 48-hour treatments at 30 degrees C. We use a direct approach selecting the specific tissue and making 'a priori' the gene election for the microarray analysis. Differential gene-expression analyses at the third antennal segments are performed comparing control and treated flies.
