In vitro biofilm formation only partially predicts beneficial Pseudomonas fluorescens protection against rhizosphere pathogens

Yang Liu, Alexandra D. Gates, Zhexian Liu, Quinn Duque, Sierra S Schmidt, Melissa Y. Chen, Corri D. Hamilton, George A. O’Toole, Cara H. Haney

This study shows that in vitro biofilm formation by Pseudomonas fluorescens does not fully predict its ability to protect plants against pathogens in the rhizosphere.

Order among chaos: high throughput MYCroplanters can distinguish interacting drivers of host infection in a highly stochastic system

Melissa Y. Chen, Leah Fulton, Ivie Huang, Aileen Liman, Sarzana S. Hossain, Corri D. Hamilton, Siyu Song, Quentin Geissmann, Kayla C. King, Cara H. Haney

This study uses MYCroplanters to identify how host, microbiota, and pathogen factors interact to influence host health in an Arabidopsis-Pseudomonas system.
