Linear correlation between gene expression and melibiose content. Significant linear relationships between melibiose and transcripts present within the weighted gene correlation network analysis module 3, for time point A (30 days of treatment). Correlations listed have |r| ≥ 0.70 and p < 0.01. Normalized expression values for each transcript are plotted on the y axis: a At1g54960–mitogen-activated protein kinase kinase kinase 2 (MAP3 K); b At4g23160–cysteine-rich receptor-like protein kinase 8 (CRK8); c At5g54160- O-methyltransferase; d At3g48300–cytochrome P450 (CYP71A23). Ambient (black, circle), elevated [CO₂] (blue, triangle), elevated temperature (red, diamond), combination (yellow, square)
