Acyrthosiphon pisum Serratia symbiotica impairs plant defence response by suppressing Ca2+ elevation and ROS accumulation, allowing coloniz… Aphis fabae No function data Adelges tsugae Serratia symbiotica helps maintain host aphid fitness during heat stress and may protect the obligate symbiont Buchnera. Acyrthosiphon pisum Serratia symbiotica enzymes may facilitate the digestion of plant proteins, thereby helping to suppress plant defense. Acyrthosiphon pisum Harris Serratia symbiotica infection made aphids more susceptible to most of the tested insecticides than non-infected aphids.
