The relative labeling in the C1 and C6 positions of carbohydrates from the ERM as a function of time after providing ¹³C₁ Glc to the mycorrhizal roots. Data are derived from the intensities of C1 and C6 signals in spectra such as those shown in Figure 1. Error bars for are ± sem for at least three replicates per experiment.
