Figure 6

Morphology of mea-1m/MEAp; ddm1-2/ddm1-2 seeds. (A–D) Wild type and three different classes of rescued seeds; the diagrams are based on observations of freshly dissected, cleared, and sectioned specimens. (A) Wild-type seed; (B) rescued seed with giant embryo and partial endosperm; (C) rescued seed with partially bent embryo and massive endosperm; (D) rescued seed with T-shaped embryo and large volume of endosperm. (E) General morphology of a rescued seed belonging to class depicted in B; (arrowhead) an abnormal region of cell proliferation in the hypocotyl. (CE) Cellularized endosperm. (F–I) Morphological analysis of rescued embryos belonging to class depicted in B. (F) Sagital section of a wild-type cotyledon. (G) Sagital section of a rescued seed cotyledon with small undifferentiated cells (arrowheads). (H) Detail of E; partially cellularized endosperm persisting at the chalazal region of a rescued seed. (Ep) Epidermis. Bars, 100 μm in A–E; 20 μ in F; 28 μm in G,H.
