Genetic organization of polysaccharide biosynthesis gene clusters in L. plantarum strains. (A) Genetic organization of the L. plantarum WCFS1 polysaccharide biosynthesis gene clusters 1, 2, and 3 (AL935263; lp_1176 through lp_1234) and comparison with the corresponding regions of L. plantarum strains ST-III (NC_014554; LPST_C0945 through LPST_C0997), JDM-1 (NC_012984; JDM1_1015 through JDM1_1041), and ATCC 14917 (ACGZ02000014; HMPREF0531_11685 through HMPREF0531_11729; ACGZ02000010; HMPREF0531_11316 through HMPREF0531_11319). Dark-grey colored connecting blocks indicate regions of high sequence conservation identified in the genomes of the indicated strains. The white area connecting msa homologues gene of ST-III and JDM-1, indicates that this gene is separated on two contigs in the draft genome sequence available for ATCC14917. (B) Genetic organization of the L. plantarum WCFS1 polysaccharide biosynthesis gene cluster 4. The corresponding regions are conserved in L. plantarum ST-III, ATCC 14917, and JDM1 sharing 99%, 99%, and 97% nucleotide identity with WCFS 1, respectively. Arrows indicate predicted promoters with e-value ≤ 10-5.
