Identification and tissue distribution of chemosensory protein and odorant binding protein genes in Tropidothorax elegans Distant (Hemiptera: Lygaeidae).

ABSTRACT: Tropidothorax elegans Distant (Hemiptera: Lygaeidae) is an insect pest that inflicts damage to vegetables and flowering plants across China. The olfactory system regulates insect behavior, such as feeding, mating, oviposition and predator avoidance. Odorant-binding proteins (OBPs) and the chemosensory proteins (CSPs) are two groups of small soluble proteins that initiate olfactory signal transduction in insects. In this study, we generated antennal transcriptomes of male and female T. elegans, and identified 19 putative OBP (14 classic OBPs and five plus-C OBPs) and seven CSP genes. Through real-time quantitative PCR analysis, we found that 14 of the 19 OBP genes were highly expressed in the antennae of both adult females and males, and 3 OBP genes were expressed higher in the antennae of
