Proteome analysis of plant-induced proteins of Agrobacterium tumefaciens.

ABSTRACT

Abstract 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 (pI 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.
