Transmission electron microscopy of developing outer endosperm cells of transformed wheat. Cr, Crystalline lattice; ib, inclusion body; p, protein body; s, starch. A, Protein bodies cluster and fuse in the central vacuole with dark-stained inclusion bodies and crystals (arrows) at the periphery. Bar = 2 μm. B, Triangular crystal at periphery of protein body. Bar = 2 μm. C, Trapezoid crystal associated with small protein bodies. Bar = 2 μm. D, Detail of inclusion body with electron-opaque regions and associated rectangular crystal with imperfections. Bar = 1 μm. E, Enlargement of region outlined in D showing crystalline lattice in the inclusion body and crystal. Bar = 100 nm.
