Fig. 3From: The role of invertases in plant compensatory responses to simulated herbivoryRelative expression of vacuolar invertase genes through developmental time (one day before clipping not shown). Shown are relative gene expression values with respect to the house keeping gene UBC9. Asterisks indicate that invertase expression differed significantly between unclipped and clipped plants at * p < 0.05 and ** p < 0.01Back to article page
