Fig. 7From: Integrated transcriptomic and metabolomic analysis reveals the effects of polyploidization on the lignin content and metabolic pathway in EucalyptusCorrelation heatmap analysis of lignin-related genes, metabolites and lignin content. The color in the heatmap represents the correlation (*P < 0.05; **P < 0.01; ***P < 0.001).Back to article page
