There are now fourteen completed genomes of bacterial phytopathogens, all of which have been generated in the past six years. These genomes come from a phylogenetically diverse set of organisms, and range in size from 870 kb to more than 6 Mb. The publication of these annotated genomes has significantly helped our understanding of bacterial plant disease. These genomes have also provided important information about bacterial evolution. Examples of recently completed genomes include: Pseudomonas syringae pv tomato, which is notable for its large repertoire of effector proteins; Leifsonia xyli subsp. xyli, the first Gram-positive bacterial genome to be sequenced; and Phytoplasma asteris, the small genome that lacks important functions previously thought to be essential in a bacterium.
