Fig. 4From: Dynamic light caused less photosynthetic suppression, rather than more, under nitrogen deficit conditions than under sufficient nitrogen supply conditions in soybeanRuBP carboxylation and regeneration capacity. The intercellular CO2 concentration (Ci) response curve of the net photosynthetic rate (Pn; a, b); the maximum rates of RuBP-carboxylation (Vcmax; c); the maximum rates of RuBP regeneration (Jmax; d); and the amounts of Rubisco, SBPase and FBPase (e) in the leaves of high nitrogen (HN; filled)- and low nitrogen (LN; closed)-supplied plants. In plot e, 1/2 and 1/4 indicate the quantity of protein sample loaded, and the number to the right of the bands indicates the protein content in LN leaves as a percentage of that in HN leaves. The original, full-length gel and blot were listed in Additional file 5. Means ± SD, n = 6 (gas exchange) or 3 (immunoblot). The asterisks indicate significant differences at P < 0.05 between HN and LN leaves (T-test)Back to article page
