Fungus-growing Allomerus ants are associated with antibiotic-producing actinobacteria
Fungus-growing attine ants use natural-product antibiotics produced by mutualist actinobacteria as ‘weedkillers’ in their fungal gardens. Here we report for the first time that fungus-growing Allomerus ants, which lie outside the tribe Attini, are associated with antifungal-producing actinobacteria, which offer them protection against non-cultivar fungi isolated from their ant-plants.
