Inoculation of Arabidopsis seedlings with Ralstonia solanacearum in sterile agar plates

Abstract

Ralstonia solanacearum invades plants through their roots and causes devastating bacterial diseases in multiple crops. Here, we present a versatile inoculation assay in Arabidopsis thaliana seedlings grown in sterile agar plates. We describe steps for plant preparation, bacterial inoculation, tissue sampling, and bacterial quantification. This protocol can be used for accurate assessment of bacterial colonization and observation of plant response to infection. For complete details on the use and execution of this protocol, please refer to Dindas et al. (2022).1
