Soilborne pathogen lab research foci:

• Evolutionary genomics & functional genetics. We use comparative, population, and functional genomics to investigate the evolutionary history of fungal pathogens. Our objectives are to fundamentally improve our understanding of the mechanisms leading to the evolution of pathogenicity. We leverage our genomic and transcriptomic resources to assess the breadth and durability of pathogen resistance in strawberry cultivars, improve molecular detection methods, and survey for the emergence of new pathogenic lineages.
• Pathogen ecology. Plant pathology research typically focuses on the interactions between a pathogen and its susceptible host. Plant pathogens also have myriad interactions with other plants, microbes, etc. that can be key to their persistence, virulence, or other important traits. Our research attempts to determine the niches occupied by plant pathogens that can lead to increased abundances in agricultural environments. By characterizing the contribution of these niches to pathogen survival, we identify key lifecycle stages that can be disrupted to reduce pathogen abundance with environmentally sustainable methods. 
• Fumigation alternatives. Soilborne pathogens of strawberries are typically managed with soilborne fumigants that can pose risks to human health and the environment. We are developing alternative methods for control of soilborne pathogens. We are working with the public and private breeding programs to evaluate cultivars and breeding material for disease resistance. In addition, we are refining techniques for anaerobic soil disinfestation (ASD), evaluating new soil steam devices, and determining the effects of crop rotation and cover cropping on pathogen survival in soil.

 

Current lab members:

Peter Henry (2019-present). Peter started the Soilborne pathogen lab at the USDA-ARS in Salinas, CA in 2019 after receiving his Ph.D. in Plant Pathology from the University of California, Davis. His interest in agriculture began while studying for a B.A. in Environmental Science from Willamette University, where he managed a student farm for two years after graduation. He enjoys hiking and appreciating the diversity of wildflowers in Big Sur. 

Polly Goldman (2019-present). Polly started as a Biological Science Technician at the USDA-ARS in 2002 after receiving her B.S. in Biochemistry from the University of California, Davis, and M.S. in Agroecology from the University of California, Santa Cruz. She is passionate about sustainable agriculture and runs variety trials for small grains and legumes for fun.

Anna Herrera (2024-present). Anna joined the lab as a Biological Science Technician in 2024. She received her B.S. in Molecular Biology from San Jose State University and her M.S. in Environmental Science from California State University, Monterey Bay.
