Differential Expression Of Snmps And Their Underlying Transcriptional Regulation In Chemosensory Pathways Of Drosophila, Richard A. Fandino
Differential Expression Of Snmps And Their Underlying Transcriptional Regulation In Chemosensory Pathways Of Drosophila, Richard A. Fandino
Theses and Dissertations
Insects possess complex and diverse chemosensory pathways which have specific phenotypes determined by the regulated expression of specific combinations of genes. While many of these genes (e.g. ORs and GRs) have very narrow expression patterns, associating with only a limited number of chemosensory sensilla, SNMPs show a very broad expression pattern. In Drosophila, SNMP1 and SNMP2 associate with the majority of olfactory and gustatory sensilla, but express in different cell types. In olfactory sensilla, SNMP1 and SNMP2 associate with trichoid or coeloconic neurons respectively, and both additionally express in a variety of sensilla support cells; in gustatory sensilla, SNMP2 expresses …
The Effects Of Snmp-2 Gene Expression On Mating Discrimination In Male Drosophila Melanogaster, Kristen Taylor Ashourian
The Effects Of Snmp-2 Gene Expression On Mating Discrimination In Male Drosophila Melanogaster, Kristen Taylor Ashourian
Theses and Dissertations
In order to distinguish between relevant and extraneous stimuli, insects have adapted specialized processes to perceive cues that are beneficial for survival and proliferation. Volatile molecules in the environment can stimulate olfactory receptors (ORs) and gustatory receptors (GRs) in chemosensory organs called sensilla. Specialized proteins located within these sensilla guide and assist chemosensory molecules to the receptors, which then trigger a transduction pathway that elicits behavioral responses. Sensory Neuron Membrane Proteins (SNMPs) are transmembrane proteins found on both gustatory and olfactory sensory organs in insects. There are two forms of these proteins, SNMP-1 and SNMP-2. InDrosophila melanogaster, the function of …
