Heatmap of important differentially expressed genes in the recombinant strain (L. lactis (MsmK)) relative to the control strain (L. lactis (Vector)) under normal (0 h) and acid-stress (2.5 h) conditions. Each gene shows the expression ratio (log2-fold change). NA represents the expression of gene was upregulated or downregulated with a less than twofold change. Genes with at least a twofold change are shown. Adjusted p < 0.05 for all data selected
