The Problem

Sustainable plant production is greatly influenced by plant-associated microorganisms. Beneficial microbes enhance plant growth and improve persistence, whereas pathogens reduce production quality and quantity. Understanding the variation of microbes, especially variation in traits related to their life strategy, is critical for understanding how these associations impact their hosts.

The Approach

The Mycology Laboratory studies beneficial symbionts of grasses and utilizes them as value-added traits in grass cultivars. In addition, the Young laboratory dissects the interaction between the pathogens Phymatotrichopsis omnivora and Fusicladium effusum and their hosts, alfalfa and pecan, respectively.
