Altered starch content and structure in the ZmDOF36- overexpressing maize lines (A) Total starch content. (B) Amylose content. (C) Absorbance spectra of isolated amylopectin-iodine complexes. Amylopectin was separated from total starch extracts and then reacted with iodine solution. BV at 680 nm and λ_max indicate the ability of starch to combine with iodine. (D) Reducing sugar content. (E) Soluble sugar content. (F) Scanning electron microscopy (SEM) images of transverse sections of maize seeds. ^∗∗Significant differences between WT and transgenic plants at P < 0.01. Scale bar = 30 μm.
