The co-expression analysis of DEGs and DEMs based on Pearson correlation. a. Interaction network of DEGs and DEMs involved in flavonoids biosynthesis in 4FADvs4WD. b. Interaction network of DEGs and DEMs associated with flavonoids biosynthesis in 8FADvs8WD. c. Interaction network of DEGs and DEMs involved in ascorbate metabolism in 8FADvs8WD. d. Interaction network of DEGs and DEMs associated with glutathione metabolism in 8FADvs8WD. Edges colored in ‘red’ and ‘green’ represent positive and negative correlations, respectively, as determined by a Pearson correlation coefficient > 0.8and or a Pearson correlation coefficient < − 0.8, respectively.
