Summary RNA transcript levels of Arabidopsis plants, infected by the rhizobacterium Pseudomonas thivervalensis (strain MLG45), and axenic control plants were compared using cDNA microarrays representing approximately 14 300 genes. The analysis revealed an increase defence‐related transcripts in shoots bacterized relative to (axenic) plants. These modifications confirmed physiological experiments. Plants with P. more resistant subsequent infections virulent pathogen syringae pv. tomato DC3000) than In addition, photosynthesis rates repressed consistently reduced growth colonized . results highlight value molecular phenotyping predict changes.
