A proteome study of Agrobacterium tumefaciens exposed to plant roots demonstrated the existence of a plant‐dependent stimulon. This stimulon was induced by exposure to cut roots and consists of at least 30 soluble proteins (p I 4–7), including several proteins whose involvement in agrobacteria–host interactions has not been previously reported. Exposure of the bacteria to tomato roots also resulted in modification of the proteins: Ribosomal Protein L19, GroEL, AttM, and ChvE, indicating the significance of protein modifications in the interactions of agrobacteria with plants.
