Effect of Ar:O2 treatment on the
concentrations of selected metabolites in nodule extracts. Data are the
means ± se (n = 3 or 4). Values
for the Ar:O2-treated plants are expressed as percentages
of the values for the control plants assayed at the corresponding
times. The mean values ± se (n =
17–20) for the control plants averaged across all times were 0.3
± 0.03 mmol Glc equivalents g−1 nodule dry weight for
starch, and 14.36 ± 0.7, 1.19 ± 0.05, 0.48 ± 0.03,
0.13 ± 0.01, 0.27 ± 0.02, 0.42 ± 0.03, 12.86 ±
0.6, 20.20 ± 1.02, and 2.85 ± 0.34 μmol g−1
nodule dry weight for Suc, Glc-6-P, Fru-6-P, Fru-1,6-bisP, PEP,
pyruvate (Pyr), malate, Glu, and Gln, respectively.
