Multilevel analysis of response to plant growth promoting and pathogenic bacteria in Arabidopsis roots and the role of CYP71A27 in this response

ABSTRACT: Understanding how plants distinguish between commensal and pathogenic microorganisms is one of the major challenges in the plant microbe interaction research. We previously identified a gene encoding CYP71A27 connected to camalexin, which is necessary for a plant growth promoting (PGP) activity of a number of bacterial strains. To dissect its function, we compared multilevel responses in roots of wild type Arabidopsis and the cyp71A27 mutant to two bacterial strains, a PGP Pseudomonas fluorescens CH267 and a pathogen Burkholderia glumeae PG1. We showed that the pathogen induces a greater reprogramming of the transcriptome, proteome, and metabolome than the PGP strain.

A major challenge in plant-microbe interaction research is understanding how plants distinguish between commensal and pathogenic microorganisms. We compared Arabidopsis responses to two contrasting bacterial strains, the plant growth-promoting (PGP) <i>Pseudomonas</i> sp. CH267 and the pathogen <i>Burkholderia glumae</i> PG1, using integrated multi-omics analyses. The pathogen triggered stronger transcriptional reprogramming and proteomic changes in roots than the PGP strain, and both strains al  ...[more]
