Physiological and comparative proteome analyses reveal low-phosphate tolerance and enhanced photosynthesis in a maize mutant owing to reinforced inorganic phosphate recycling

Table 3 Influence of different phosphate treatments on sucrose, starch and chlorophyll contents

Three seedlings per bottle were cultured in phosphorus saturation solution (1000 μM KH₂PO₄) to the three-leaf stage, followed by low phosphate stress solution (5 μM KH₂PO₄) for an additional 25 days to the six–seven-leaf stage. Values represent the means of nine seedlings ± SD. Values with different letters within a row are significantly different (P < 0.05) by multiple comparison analysis
