摘      要:The soybean aphid,Aphis glycines,is an extreme specialist and an important invasive pest that relies on olfaction for behaviors such as feeding,mating,and ***-binding proteins(OBPs)play a vital role in olfaction by binding to volatile compounds and by regulating insect sensing of the *** this work we used rapid amplification of complementary DNA ends technology to identify and characterize 10 genes encoding *** OBPs(AglyOBPs)belonging to 3 subfamilies,including 4 classic OBPs,5 Plus-C OBPs,and one Minus-C *** real-time polymerase chain reaction demonstrated variable specific expression patterns for the 10 genes based on developmental stage and aphid tssue *** levels of 7 AglyOBPs(2,3,4,5,7,9,and 10)were highest in the 4th instar,indicating that the 4th nymphal instar is an important developmental period during which soybean aphids regulate feeding and search for host ***-specific expression results demonstrated that AglyOBP2,7,and 9 exhibited significantly higher expression levels in ***,ligand-binding analysis of5 OBPs demonstrated binding of AglyOBP2 and AglyOBP3 to a broad spectrum of volatiles released by green leaf plants,with bias toward 6-to 8-carbon chain volatiles and strong binding of AglyOBP7 to *** together,our findings build a foundation of knowledge for use in the study of molecular olfaction mechanisms and prov ide insights to guide future soybean aphid research.
