The research results were published in《Insect Biochemistry and Molecular Biology》 in 2018.SDS of cas: 78-69-3 The article conveys some information:
Plant volatiles are vital cues in the location of hosts for feeding and oviposition for Lepidoptera moths. The noctuid Helicoverpa assulta is a typical polyphagous moth, regarded as a good model for studying the olfactory reception of plant volatiles. In this study, four full-length genes encoding odorant receptors HassOR24, HassOR40, HassOR41, and HassOR55 expressed in antenna in H. assulta were functionally characterized. The highly expressed HassOR40 was narrowly tuned to a few structurally-related plant volatiles: geranyl acetate, geraniol and nerolidol. By systematically analyzing responses of single neuron in both trichoid sensilla and basiconic sensilla using single sensillum recording, the specific neuron B in one type of short trichoid sensilla was found to be mainly activated by the same chems. as HassOR40 with high sensitivity, and with no significant difference between male and female neurons. Thus, a clear “receptor-neuron” relationship in H. assulta was demonstrated here, suggesting that HassOR40/HassOrco are expressed in neuron B of short trichoid sensilla. The active tobacco volatile nerolidol, recognized by this receptor-neuron line, elicits significant behavioral attraction of both sexes in H. assulta adults. The results indicate that we identified a receptor-neuron route for the peripheral coding of a behaviorally relevant host volatile in H. assulta. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .
3,7-Dimethyloctan-3-ol(cas:78-69-3) is a fatty alcohol that is 3-octanol substituted by methyl groups at positions 3 and 7.SDS of cas: 78-69-3 Metabolite observed in cancer metabolism. It has a role as a human metabolite.
