Correlation analysis between microbial flora (relative abundance of the top 20) with FAAs, chemical elements, and chemical constituents of filler tobacco leaves. Heat map of correlation between bacterial (A) with fungal (B) and FAAs; heat map of correlation between bacterial (C) with fungal (D) and chemical elements and chemical constituents; Blue and green represent positive correlation, red and purple represent negative correlation. Significant correlations were expressed by *, * *,* * * and * * * * which were p < 0.05, p < 0.01, p < 0.001 and p < 0.0001, respectively
