What is one key mechanism by which endophyte-infected tall fescues resist pests?

Explanation:
Pest resistance from endophyte-infected tall fescue comes from chemical defenses produced by the endophyte fungus. The endophyte synthesizes alkaloids that act as feeding deterrents or toxins to many pests, so insects and other herbivores are less likely to feed on or survive on the plant. These compounds accumulate in the plant tissues, giving the grass a built-in defense without needing to change the plant’s photosynthesis or attract pests. In short, alkaloids produced by the endophyte deter pests and reduce damage.
