Asexual fungal symbionts alter reproductive allocation and herbivory over time in their native perennial grass hosts.

Abstract excerpt

Although most plants harbor microbial symbionts, the temporal effects of symbionts on resource allocation and herbivore resistance of perennial hosts are unknown. Neotyphodium endophytes are asexual, vertically transmitted fungal symbionts of grasses that are thought to interact mutualistically with their hosts, mainly by deterring herbivores. To test age-specific effects of Neotyphodium infection and herbivory...
