Abstract/OtherAbstract:
Sensory neuron membrane proteins (SNMPs) are olfactory-specific, two-transmembrane proteins. Previous publications reported that SNMP1 is expressed on the dendrite membrane of pheromone-sensitive neurons in Heliothis virescens and is an essential cofactor for pheromone detection in Drosophila. In this study, we cloned two SNMP genes (GenBank accession nos. JX469106 and JX469107) from the antenna of the beet armyworm moth Spodoptera exigua (Lepidoptera: Hübner). These SNMP genes are classified into two highly conserved subclades, indicating their importance in physiological activity of lepidopteran insects. SexiSNMP1 is antenna-specific in male and female adults, while SexiSNMP2 is antenna-abundant but also expressed in other chemosensory tissues, particularly proboscises and maxillary palps of adults both sexes. In situ hybridization revealed that both SNMPs are broadly expressed in long and short trichoid and basiconic sensilla. We infer that SNMP1 and SNMP2 act in the detection of the sex pheromone and general odorants.
