    workers offer to fungus gardens. One of the symbionts is specific to the leaf-cutting ants and has special genomic machinery to catabolize citrate/glucose into acetate, which appears to deliver direct metabolic energy to the ant workers.

    , both attine ant strains have complete phage-defense systems, underlining that they are actively maintained as mutualistic symbionts.
