Plant-specific pathogen that causes citrus canker. Xanthomonas citri pv. citri str. 306

Xanthomonas axonopodis pv. citri str. 306. This strain contains genes that are similar to genes from another citrus pathogen, Xylella fastidiosa. It has 2 different type II secretion system for the export of extracellular enzymes that degrade the plant cell wall including cellulases. The genome encodes a single type III secretion system (Hrp) that is important for pathogenicity as well as two type IV secretion system, one on the chromosome and one found on one of the two plasmids this organism contains, pXAC64.
