Abstract

A combined computational and experimental analysis of metabolism in the symbiosis between the pea aphid and its obligate endosymbiont Buchnera aphidicola redefines existing notions of symbiotic nitrogen recycling. As a consequence of metabolic pathways shared between the partners, the insect recycles waste ammonia into essential amino acids (EAAs) that are lacking in its diet of sugar-rich but nitrogen-poor plant phloem sap.
