Open AccessComplex host-pathogen coevolution in the Apterostigma fungus-growing ant-microbe symbiosis
The fungus-growing ant-microbe symbiosis consists of coevolving microbial mutualists and pathogens. The diverse fungal lineages that these ants cultivate are attacked by parasitic microfungi of the genus Escovops...
