From plants to ants: Evaluating lipidomic changes in leaf-cutter ant fungus gardens

ABSTRACT: Leaf-cutter ants use fresh plant material to cultivate an obligate mutualistic fungus Leucoagaricus gongylophorus in specialized fungus gardens to access and transform nutrients from plant biomass that would otherwise be unavailable to the ants. Here, we evaluated the lipidomic differences between the leaves feeding the gardens, gongylidia produced by the fungus to feed the ants, and spatially-resolve regions of the fungus garden at initial to advanced stages of leaf degradation.

Lipids are essential to all living organisms, as an energy source, as an important cellular structural component, and as a communication tool. In this study, we used global lipidomic methods to evaluate the lipids in leaf-cutter ant fungal gardens. Leaf-cutter ants and their coevolved fungal cultivar, <i>Leucoagaricus gongylophorus</i>, are a model mutualistic system. The fungus enzymatically digests fresh plant material that the ants cut and deliver, converting energy and nutrients from plants  ...[more]
