INTRODUCTION
The ability of plant pathogenic bacteria to deliver death-
triggering proteins to the interior of plant cells was revealed in
a rapid succession of papers in 1996 that transformed our
concepts of bacterial plant pathogenicity. The breakthrough
came with the convergence of work on Hrp systems and Avr
proteins, an understanding of which requires an introduction
to the most prevalent bacterial pathogens of plants, the cardi-
nal importance of the Hrp pathway, and the paradoxical phe-
notype associated with avr genes.
