FIG 3.

Genetic organization of the T6SS cluster in Helicobacter pullorum. The T6SS gene order and content are displayed for Helicobacter pullorum strains and also for Campylobacter jejuni strain 414 (top row), for comparative purposes. Genes are plotted as arrows (size proportional to gene length) whose direction indicates the chromosomal strand. Genes encoding proteins related to the T6SS are in black. Genes located in regions displaying variability in the genetic content among Helicobacter pullorum strains (highlighted by gray dashed lines) are in gray. The gene organization of the T6SS for strain 229334/12 is not shown because assembly issues yielded the T6SS genes in more than one contig. However, the draft genome of this strain carries all of the genes related to the T6SS.
