Embryo and Endosperm Are Altered in mppr6 Mutant Kernels.

The 12-µm longitudinal wax sections of mutant ([B], [D], [F], and [H]) and wild-type ([A], [C], [E], and [G]) kernels at 12 DAP stained with Azure B ([A] to [F]) and periodic acid Schiff’s reagent ([G] and [H]). In (B), double arrows indicate the gap between pericarp and aleurone, whereas arrows in (D) and (F) show abnormal cells in the BETL. csen, central starchy endosperm; e, embryo; en, endosperm; p, pedicel; pc, pericarp. Bars = 1 mm in (A) and (B), 100 µm in (C) and (D), 60 µm in (E) and (F), and 40 µm in (G) and (H).
