Bacterial Pathogenesis

assays, the discovery of more subtle mutant phenotypes, and advances in
plant biology will continue to drive progress. But two new areas will ulti-
mately become important. The first is the biochemical study of the many
protein-protein interactions that surely underlie the function of the Hrp
system. The second is the application of cell biological techniques to
observe more dynamically the interactions between individual plant and
bacterial cells.
