Maria Harrison

Education She received her PhD in biochemistry from the University of Manchester in 1987 for research investigating gene expression in tomato seeds supervised by T.A. Brown.

Career and research Harrison's lab, including post-doctoral, graduate, undergraduate, and intern students, utilizes a combination of molecular, cell biology, genetic, and genomic techniques to investigate the developmental mechanisms underlying the symbiosis and phosphate transfer between arbuscular mycorrhizal fungi (AM fungi; AMF) (including Glomus versiforme, Glomus intraradices, and Gigaspora gigantea) and the roots of model legume Medicago truncatula. Among Harrison's most notable findings are that plants use hormone signaling to regulate AM fungi symbiosis and that phosphate transport is critical to the maintenance of this symbiosis. These discoveries have allowed the field of fungal-plant interactions to pursue new research questions including future manipulation of phosphate acquisition in valuable crop species. and a Fellow of the Royal Society (FRS) in 2024.
