Gene expression analysis. (A): PCA analysis of gene expression between samples; (B): Venn diagram analysis; (C): number of differentially expressed genes; (D): volcano plot of pH 4.0 vs. pH 7.0; (E): volcano plot of pH 4.0 vs. pH 10.0; (F): volcano plot of pH 7.0 vs. pH 10.0. In (D–F), the green dots represent down-regulated differentially expressed genes, the red dots represent up-regulated differentially expressed genes, and the black dots represent non-differentially expressed genes).
