| Research Abstract |
I examined the mechanisms underlying host plant adaptation of the pea aphid Acyrthosiphon pisum governed by an endosymbiotic bacterium Regiella. Analyses suggested that this phenomena was caused by 1) different amino acids composition between host plants, and 2) complex biological interactions between Regiella and essential symbiont Buchnera those were influenced by amino acids compositon of the host plant. It was also revealed that transplant of Regiella symbiont improved adaptation of the vetch aphid Megoura crassicauda on the white clover.
