Identification, expression and functional prediction of odorant degrading enzymes in the antennal transcriptome of
Abstract:
Anoplophora glabripennis, a major pest causing significant economic harm in China, affects a variety of hosts such as Salix, Ulmus, and Populus. Our research uncovered the mechanism of antennal odorant-degrading enzymes (ODEs) in this pest, identifying 97 ODEs, which include 9 GSTs, 20 CXEs, 66 P450s, and 2 UGTs. qPCR revealed sex-biased expression of specific ODEs, with some potentially involved in detoxification and pheromone degradation in males, and others in plant odor detection for oviposition in females. Highly expressed ODEs in both sexes may perceive food source odors. Molecular docking showed 3-Carene had the highest binding affinity to key ODEs, with AglaCYP345N1 binding most effectively and AglaGSTD4 the least. This research provides insights into the chemical ecology of A. glabripennis, potentially aiding in the development of monitoring and control strategies for this pest.
