Symbiosis is a widespread phenomenon in nature and represents a major force in adaptation and evolution. Epigenetic switches enable different phenotypic states to be present in a genetically identical population, potentially facilitating rapid species adaptation. The impact of symbiosis establishment and maintenance on host epigenetic mechanisms remains elusive.

Pesticides are intensively used to protect cereals from pests, but they are known to increase pest resistance and affect the environment and non-target organisms, including humans, which points to the need for sustainable alternatives. Some of the main cereal pests are the weevil Sitophilus spp., which proliferate on a cereal-exclusive diet thanks to a mutualistic association with the intracellular symbiotic bacterium (endosymbiont), which provides the insect the nutrients that are scarce in the grains.
