Figure 3.

The orthologous T6SS-1 loci in Pantoea and Erwinia species. The conserved regions (block I and III) are shaded in gray, while the non-conserved hcp and vgrG islands are not shaded. Genes encoding conserved domain proteins identified by Boyer et al. [15] are represented by green arrows, and grey arrows indicate other genes conserved among the Pantoea and Erwinia T6SS-1 loci which were not identified as part of the conserved core described by Boyer et al. [15]. Red arrows represent the hcp and vgrG genes while genes not conserved among the Pantoea and Erwinia species are colored in white.
