Bacterial diseases cause significant losses in many crops, and control measures are often limited or unavailable. The majority arise from invasion of the vascular system or colonization of the leaf parenchyma. The major classes of molecular tools that enable bacteria to thrive inside plants are beginning to be understood, but little is known about the functions within the plant of most of these tools. Less still is known about the plant signals and targets that render plants susceptible. Virtually nothing is known of the basis for tissue specificity.
