Fig. 6.
Changes of metabolites for the TCA cycle and amino acid synthesis during photosynthetic induction. Vertical and horizontal axes represent metabolite content (μmol m−2) and times after illumination (min), respectively. Asterisks indicate significance at *P<0.05, **P<0.01, and ***P<0.001 between cultivars (t-test). ns, no significant difference. Values are means ±SE (n=6). PEP, phosphoenolpyruvate; 2OG, 2-oxoglutarate;. (This figure is available in colour at JXB online.)
