Maltose content in leaves of WT (Col-<i>0</i>), <i>aps1</i>, <i>pgm</i>, <i>aps1/pgm</i>, <i>mex1/aps1</i> and <i>mex1/pgm</i> plants.

<p>Leaves of the indicated plants were harvested at the 18 DAS growth stage. Values obtained using HPAEC-PAD and GC-MS are represented with white and grey columns, respectively. Values represent the means ± SE determined from three independent experiments using 6 plants in each experiment. Asterisks indicate significant differences according to Student´s t-tests (*<i>P</i><0.05, <i>aps1</i>, <i>pgm</i> and <i>aps1/pgm</i> vs. Col-<i>0</i>; **<i>P</i><0.05, <i>mex1/aps1</i> vs. <i>aps1;</i> ***<i>P</i><0.05, <i>mex1/pgm</i> vs. <i>pgm</i>). Values correspond to plants cultured under continuous light (CL) conditions. Essentially the same results were obtained using plants cultured under long day (LD) conditions (not shown).
