A β-glucuronidase (GUS) Based Bacterial Competition Assay to Assess Fine Differences in Fitness during Plant Infection
Authors:  Julien S. Luneau, Laurent D. Noël, Emmanuelle Lauber and Alice Boulanger, date: 07/05/2022, view: 1257, Q&A: 0

Competition assays are a simple phenotyping strategy that confront two bacterial strains to evaluate their relative fitness. Because they are more accurate than single-strain growth assays, competition assays can be used to highlight slight
