Barbara Keith

Barbara Keith serves as an Assistant Research Professor in the Department of Plant Sciences & Plant Pathology at Montana State University's College of Agriculture, specializing in herbicide resistance mechanisms and plant-microbe symbiosis.

Her academic credentials include:

• Ph.D. in Microbiology and Immunology from Hahnemann University (1996)
• B.S. in Microbiology from the University of Washington (1988)

Dr. Keith's research investigates molecular pathways of multiple herbicide resistance in weeds, particularly Avena fatua (wild oat). She examines constitutive changes in redox systems, phosphoproteomes, and stress-responsive gene expression resulting from intensive herbicide exposure, while also exploring endophytic interactions that may influence plant resilience. Her work bridges fundamental molecular biology with practical weed management strategies.

Analysis of her 2017-2020 publications reveals a cohesive research trajectory using integrated 'omics approaches (proteomics, transcriptomics, biochemistry) to decode resistance mechanisms across biological scales—from gene regulation to population dynamics—with significant implications for sustainable agriculture.

She has secured competitive funding from USDA NIFA for projects investigating context-dependent resistance evolution and detection methods for herbicide-resistant weed populations. Collaborative publications indicate active partnerships with weed scientists including W. Dyer and E.E. Burns, though formal student advisement is not documented.

Her research operates within Montana State University's agricultural science infrastructure, contributing to the department's mission in plant pathology and sustainable crop protection.
