Fig. 8From: Transcriptomic and metabolomic analyses reveal how girdling promotes leaf color expression in Acer rubrum LOPLS-DA S-plot (The abscissa represents the covariance between principal components and metabolites, and the ordinate represents the correlation coefficient between principal components and metabolites. The metabolites closer to the upper right corner and lower left corner in the figure indicate more significant differences. Red dots indicate that the VIP of these metabolites is ≥ 1, while green dots indicate that the VIP of these metabolites is < 1.)Back to article page
