Food security for leaf-cutting ants: Workers and their fungus garden reject endophyte invaders
New diseases directly affect human survival and food security, especially as population density climbs. Leaf-cutting ants, one of a few groups of social insects to cultivate crops, have harvested plant material to fertilize their underground fungal gardens for ~50 million years. New results from t...
