Figure 6.

TEMs of wild-type and ethe1 seeds at late globular stage. Micrographs of endosperm (oriented to bottom; A and B) and adjacent basal cells of the suspensor (C and D) in the wild type (A and C) and ethe1 (B and D). Plasmodesmata (asterisk) are present between cells of the suspensor. Small chloroplasts are visible in the endosperm (Chl) and mitochondria (arrowheads) and large and small vacuoles are present in both endosperm and suspensor cells. Wild-type mitochondria have electron lucent interiors with cristae located at the periphery. The interior of most ethe1 mitochondria contain electron-dense inclusions. Size bars = 1 mm.
