Figure 3
Effects of Pi application on the sugar-phosphate and adenylate content
in rice leaves. (a) shows the scheme of sugar-phosphate metabolism in
the chloroplasts and cytosol. The sugar-phosphate content described as
red-characters indicate those quantified in this study. (b) shows the
sugar-phosphate content in rice leaf blade. White, blue, dark blue,
purple, pink, and red bars indicate low (0.06 mM), control (0.6 mM), 1.2
mM, 1.8 mM, 2.4 mM, and 3.0 mM treatment conditions, respectively. (c)
and (d) show adenylate content and ATP/ADP ratio in rice leaf blade.
These results are expressed as mean ± SD (n = 3-9). Different alphabets
indicate significant differences among different Pi application
conditions (Tukey-Kramer’s HSD test, p < 0.05).
