Adventures with Arbuscular Mycorrhizal Fungi: Host regulation under combinatorial nutrient stress

Arbuscular mycorrhiza (AM) are a class of mutualistic, plant root-associated fungi that are believed to have helped make the terrestrialization of modern land plants possible. As an obligate mutualist, AM are dependent on their host plants for carbon in the form of photosynthesis-derived sugars and fatty acids. In return, AM are able provide mineral nutrients, such as phosphorus and nitrogen, to their hosts by accessing soil at further distances and greater granularity. This talk will incorporate biochemical, genetic, transcriptomic, and physiological approaches to investigate how nitrogen and phosphorus signaling are involved in the regulation of symbiotic relationships between arbuscular mycorrhizae and host plants, using rice as a model system. Broadly, this work aims to fill in knowledge gaps in plant nutrient uptake both with and without mutualists with the hope of decreasing agricultural dependency on costly synthetic fertilizers.
