Fig. 1 The main nutritive components. Figures a-f show the nutritive components of Auricularia cornea cultivated with different substrates respectively. Different lowercase letters indicate the significant difference (P<0.05).
Fig. 2 PCA score plot. A: Miscellaneous sawdust, control; B: Eucalyptus sawdust; C: Eucalyptus bark. The same below.
Fig. 3 OPLS-DA score plot. Figures a, b and c show the OPLS-DA score plot of A&B, A&C and B&C respectively.
Fig. 4 OPLS-DA permutation test plots. Figures aʹ, bʹ and cʹ correspond to comparison groups A&B, A&C and B&C respectively. R² represents the cumulative variance value of the model; Q² represents the cumulative cross validation of the model; R²Y (cum) represents cumulative interpretation rate.
Table 2 Different metabolites among treatment groups
Fig. 5 Hierarchical clustering heat map. Figures a, b and c correspond to comparison groups A&B, A&C and B&C respectively. Each row represents a metabolite; Each column represents metabolites from different samples; Red indicates high metabolite content; Green indicates low metabolite content.
Table 3 KEGG pathway annotation
Fig. 6 KEGG enrichment pathway diagram. Figures a, b and c show the KEGG enrichment pathway of A&B, A&C and B&C respectively. Each bubble represents a pathway; Abscissa represents the impact value in the pathway; Ordinate represents the enrichment significance of metabolites in the pathway -log₁₀ (P-value); Bubble size represents the impact value; The larger the bubble, the greater the importance of the pathway. Bubble color from light to deep indicates that P-value decreases in turn.
