摘要：

Odorant-binding proteins (OBPs) and chemosensory proteins (CSPs), which are thought to play key roles in the olfactory recognition of insects, can be induced by the odorants they recognize, but little is known about the underlying regulatory mechanisms. Here, we found that NlOBP8 and NlCSP10 play coordinative roles in the chemoreception of brown planthoppers (BPHs) to the volatile component linalool. Also, the relative mRNA levels of NlObp8 and NlCp10 decreased upon exposure to linalool. Further, homeotic protein distal-less (Dll), which was also highly expressed in the antennae, was found to positively regulate the transcription of NlObp8 and NlCsp10 directly. Knocking down NlDll expression downregulated the expression of many additional olfactory functional genes and impaired the repellent behavior of BPHs to linalool. Our findings elucidate the direct regulatory role of Dll in BPHs' olfactory plasticity to linalool through modulating the olfactory functional gene expression and could provide guidance to sustainably control BPHs in the field.
