Mysterious protein sets up a beneficial partnership between bacteria and insects
Nature, Published online: 01 July 2026; [doi:10.1038/d41586-026-02007-4][1]
Buchnera bacteria that live in the cells of insects known as aphids secrete a protein called SyeA, which is crucial for colonization. The structural similarity of SyeA to proteins secreted by disease-causing bacteria indicates that the beneficial symbiotic relationship between Buchnera and aphids had pathogenic origins.
