Addressing the Puzzle of Time-Varying, Bidirectional Flows in Arbuscular Mycorrhizal Fungi Networks

2023 Faculty Research Award

AWARD PERIOD: 2023-2025

Howard Stone, the Donald R. Dixon ’69 and Elizabeth W. Dixon Professor in the mechanical and aerospace engineering department, investigates how arbuscular mycorrhizal fungi (AMF) are part of a symbiotic relationship responsible for significant fluid transport networks below ground. These networks, in turn, provide nutrients that make plant life possible. The fluid dynamics of AMF are distinct from other plant networks but remain poorly understand, though recent research has highlighted previously unknown time varying, bidirectional hyphal (threads that make up the mycelium of a fungus) fluid flows characteristic of the AMF transport network. This research raises many new questions important to the ecology, development, and environmental responsiveness of AMF and their central role in life in soils. The project plans to develop the first models of internal fluid flows of hyphal networks, and the bidirectional transport that they enable.

The project will offer undergraduate students the opportunity to write senior theses on the research topic with special emphases on science, sustainability, and biodiversity themes informed and motivated by the impact of mycorrhizal fungi on underground transport processes and physical chemistry. Professor Stone will also provide independent work for undergraduates and summer research experiences through the HMEI internship program.
