Genes of T6SSc presence in the 61 Enterobacterales genomes. A total of 61 of the 203 Enterobacterales genomes possessed the T6SSc cluster. The strains with red letters were from the newly sequenced genomes in this study; the others strains were from NCBI. The 28 genes of T6SSc of the BCS7 strain was used as a standard; we grouped the genes into two Blocks (Block I includes the first 8 genes (starting from the 5′ end) of the cluster; Block II includes the 20 terminal genes of the cluster at the 3′ end). Map showing the presence (black feature) or absence (grey feature) of each gene of the T6SSc cluster, with a maximum likelihood phylogenetic tree based on the core genes of 61 Enterobacterales genomes. Colored arrows indicate five clusters that divide these strains into different known families (Enterobacteriaceae, Erwiniaceae, Morganellaceae & Yersiniaceae, Budviciaceae & Hafniaceae, and Pectobacteriaceae) of the Enterobacterales order. a and b: two different sequenced genomes (accession numbers: NZ_JIBO00000000 and NZ_FNQS00000000) of the Lonsdalea quercina subsp. quercina strain ATCC 29281T, respectively. The frequency percentage of each gene of T6SSc among these genomes is shown on the right side next to the physical map
