Nature, Published online: 01 July 2026; doi:10.1038/d41586-026-02007-4 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.
The discovery of SyeA's role and its structural similarity to pathogenic proteins provides a novel insight into the evolutionary origins of symbiosis, published in Nature.
This research reveals a fundamental mechanism of beneficial biological partnerships and suggests a potential pathway for engineering complex symbiotic relationships, impacting various biological applications.
Understanding that beneficial symbiosis can arise from pathogenic origins challenges previous assumptions and opens new avenues for synthetic biology and therapeutic development.
