In insects, Odorant binding proteins (OBPs) and chemosensory proteins (CSPs) are highly expressed in olfactory organs and play essential roles in perceiving female pheromone and host volatiles by binding and transporting odorant compounds. In this study, 17 OBPs and 16 CSPs were identified from <em>P. songi</em> by transcriptome analysis. Sequence alignment indicated that PsonOBPs and PsonCSPs share no identity with each other in protein sequence. The overall structures of PsonOBPs and PsonCSPs are mainly constructed by α-helix bundles and loops. But the distribution of conserved cysteine residues and arrangement of α-helix are varied between PsonOBPs and PsonCSPs. Putative ligand binding cavities were found in these predicted protein structures. Expression profiles of PsonOBPs and PsonCSPs in adults and larvae were determined by RT-PCR which showed that 16 PsonOBPs and 11 PsonCSPs were expressed in adult antennae or/and larval head. PsonGOBPs, PsonPBPs, PsonOBP5, PsonOBP7, and PsonCSP6 were preferentially expressed in olfactory associated tissues. Our results suggest that the PsonOBPs and PsonCSPs that contain ligand cavity and are highly enriched in olfactory tissues may play roles in chemosensory perception of <em>P. songi</em>, and the transcriptome data may facilitate the studies on the olfactory mechanism of <em>P. songi</em> specifically choosing <em>E. ulmoides</em> as host.</p></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"27 2","pages":"Article 102255"},"PeriodicalIF":1.5,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140843541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
