Large-scale candidate gene scan reveals the role of chemoreceptor genes in host plant specialisation and speciation in the pea aphid

Targeted resequencing in the pea aphid Acyrthosiphon pisum. We captured and sequenced some chemosensory genes (OR, GR, OBP, CSP) potentially involved in host plant specialisation and speciation among three pea aphid host races (Medicago, Trifolium, Lotus).

本研究针对豌豆蚜（Acyrthosiphon pisum）开展靶向重测序。我们对三个豌豆蚜寄主宗（苜蓿属Medicago、三叶草属Trifolium、百脉根属Lotus）中可能参与寄主植物专化及物种形成的化学感受基因——包括嗅觉受体（Odorant Receptor, OR）、味觉受体（Gustatory Receptor, GR）、气味结合蛋白（Odorant Binding Protein, OBP）与化学感受蛋白（Chemosensory Protein, CSP）——进行了捕获与测序。
