Linking phosphorus and carbon in rhizosphere nutrient cycling

Lead Institution

Michigan State University

Principal Investigator

James Moran

Plant root exudates provide a significant carbon (C) source for rhizosphere microbial communities. In return, these communities help mobilize nutrients needed for plant growth. For instance,…

Identification of plant host and microbe model system for study of rhizophagy cycle

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Vivian Lin

Rhizophagy (“root eating”) is a process by which plants actively uptake soil microbes into their roots and use oxidative degradation to extract micronutrients from the cells. This phenomenon has been…

Development of in vitro glycosylation toolkit to study eukaryotic glycoproteins

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Irina El Khoury

When working with glycoproteins from native sources, biochemical analysis is often hampered by sample heterogeneity and glycan-postprocessing structural diversity. It is therefore desirable to create…
