Maria Harrison featured in interview with International Society for Molecular Plant-Microbe Interactions
In this IS-MPMI’s interview with Kevin Cope (University of Wisconsin-Madison), Maria Harrison discusses her research on arbuscular mycorrhizal fungi and provides advice to young scientists entering the field.
Maria Harrison, consortium of scientists receive $5 million grant to study genes that help legumes access soil nutrients
BTI’s Harrison lab will develop Medicago truncatula mutants to identify the function of genes predicted to be important in nitrogen fixation in legumes.
Researchers from the Harrison lab at BTI have identified a transcriptional program that drives arbuscule degeneration during AM symbiosis. This regulation of arbuscule lifespan has likely contributed to the 400MY stability of the symbiosis by preventing the persistence of fungal cheaters.
Researchers from the labs of Dr. Maria Harrison at the Boyce Thompson Institute and Dr. Peter Dörmann at the University of Bonn have produced the first experimental evidence to suggest that AM fungi also get lipids from the plant. AM-induced FatM and RAM2 may play specific roles in the biosynthesis of 16:0 βMAG, which cannot be produced by the fungus, providing a clue to understanding the obligate nature of AM fungi.
“Food security is a mixture of all the different aspects of agriculture. It’s not just growing the food,” said Proctor. “It’s not just planting something in the ground – there is a lot more to it.”
BTI researchers used a genome comparison approach to identify genes necessary for beneficial plant-fungal relationships, which may lead to better crop plants that require less fertilizer input.
Fluorescent proteins will allow researchers to track phosphate movement through cells in real time.
Maria Harrison will participate in a $13.5 million, multi-institution systems biology project with Daniel Schachtman of the University of Nebraska-Lincoln to develop sorghum that is more drought resistant and uses nitrogen more efficiently.
BTI researchers Harrison and Floss collaborate with Cornell physicists to understand how roots grow around barriers in the soil, while still heading down.
Harrison Lab has discovered that plants use EXO70I to form a membrane around the fungus in arbuscular mycorrhizal (AM) symbioses, beneficial associations where plants receive phosphate from fungi in exchange for carbohydrates.
BTI Professor Emeritus Robert Kohut initiates competition at BTI to give early-career scientists an opportunity to communicate with the general public and practice their “elevator speech.”
Marshall Tyler nominated Maria Harrison for the 2015 Cornell University College of Agriculture and Life Sciences Faculty Excellence in Undergraduate Research Mentoring Award.
The discovery of the role of this ammonium transporter improves the understanding of how the plant and fungal partners regulate the symbiosis and how phosphate and nitrogen move through the system.
Professor Maria Harrison is the 2015 winner of the Dennis R. Hoagland Award from the American Society of Plant Biologists, given every three years, for her outstanding work on plant mineral nutrition.
James Eaglesham began his career as an intern at BTI, and heads to the University of Cambridge, England as a Churchill scholar for pathology research. When back in US, Eaglesham will pursue his doctorate in virology at Harvard, in Cambridge, MA.
The research project will study genes responsible for beneficial symbioses with bacteria and fungi. Work in the Harrison lab will focus on the plant-fungal AM symbiosis and how it improves phosphorus uptake in plants.
At its May meeting, the BTI Board of Directors named Maria Harrison as the William H. Crocker Scientist.
