Clustered heat map of correlation analysis of DEGs and DEMs after the treatment of different alkali concentrations in M. nipponense. The clustered heat map with genes in columns and metabolites in rows to show the connection between genes and metabolites. The positively and negative correlation among transcriptomics and metabolomics were showed by the red and blue, respectively. (A): Correlation analysis of DEGs and DEMs between 0 mmol/L vs. 4 mmol/L; (B): Correlation analysis of DEGs and DEMs between 4 mmol/L vs. 8 mmol/L; (C): Correlation analysis of DEGs and DEMs between 8 mmol/L vs. 12 mmol/L
