Systemic Resistance in Arabidopsis lnduced bY Biocontrol Bacteria 1s lndependent of Salicylic Acid Accumulation and Pat hogenesis-Related Gene Expression


Systemic acquired resistance is a pathogen-inducible defense mechanism in plants. The resistant state is dependent on endogenous accumulation of salicylic acid (SA) and is characterized by the activation of genes encoding pathogenesisrelated (PR) proteins. Recently, selected nonpathogenic, root-colonizing biocontrol bacteria have been shown to trigger a… (More)
