Most aphids host mutualistic bacteria, Buchnera aphidicola, which live inside specialised cells called bacteriocytes. Buchnera are vital to the aphids well being as they provide essential amino acids that are scarce in its diet. Now research published in the open access journal BMC Biology suggests that the aphids' ability to host Buchnera depends on genes they acquired from yet another species of bacteria via lateral gene transfer (LGT)...
