Figure 4.

Region containing citrus-canker specific effector genes xopE3 and xopAI. The XAC region depicted is hypothesized to be a genomic island [14]. The central parts of this region (gray areas) are CC-specific, being present in both XauB and XauC as well as in XAC plasmid pXAC64. Gene mltB is not an effector but plays a role in Type III secretion.
