Proposed fermentative metabolic pathways of Leu. mesenteroides for carbohydrates and their transcriptional expressions during kimchi fermentation. Metabolic pathways that were present in all Leu. mesenteroides strains are depicted in blue (core-genome) and metabolic pathways that were present in 15–16 Leu. mesenteroides strains are depicted in violet (soft core-genome). Metabolic pathways that were present in 1–14 Leu. mesenteroides strains are depicted in red (unique- or accessory-genome). Line thickness in the pathways is proportional to the number of Leu. mesenteroides strains harboring the corresponding genes, which are indicated in parentheses before EC numbers. Carbohydrate transport systems with black arrows indicate unidentified transporting systems that may be present in Leu. mesenteroides genomes. The transcriptional expressions were visualized by heatmaps based on their RPKM values and the white boxes represent no transcriptional expression during kimchi fermentation. Kimchi samples for the metatranscriptomic analysis were obtained at 7, 13, 18, 25, and 29 days. UDP, uridine diphosphate.
