Gene neighborhoods of vgrG homologs. The grouping and labeling of vgrG homologs are based on the convention used in Fig. 3. For each vgrG homolog, three upstream genes are plotted to illustrate if it is associated with the main T6SS gene cluster or not, and 10 downstream genes are plotted to illustrate putative effector/immunity genes. Two A1-type homologs from the strain S56 (i.e., AGR1B_RS27940 and AGR1B_RS27960) are in close association with each other and plotted together
