met1-6 Mutation Affects Suspensor and Embryo Development.
(A) to (X) Nomarski photographs of wild-type and homozygous met1-6 mutant embryos at 1 to 6 DAP.
(Y) to (JJ) Histological section photographs of wild-type and met1-6 mutant embryos at 4 to 6 DAP.
Photographs of the wild type (A) to (F) at 1, 2, 3, 4, 5, and 6 DAP, respectively; the met1 mutant embryos at 1 DAP ([G], [M], and [S]), 2 DAP ([H], [N], and [T]), 3 DAP ([I], [O], and [U]), 4 DAP ([J], [P], and [V]), 5 DAP ([K], [Q], and [W]), and 6 DAP ([L], [R], and [X]). Histological sections of wild-type embryos (A) to (C) at 4, 5, and 6 DAP, respectively; the met1 mutant embryos at 4 DAP ([BB], [EE], and [HH]), 5 DAP ([CC], [FF], and [II]), and 6 DAP ([DD], [GG], and [JJ]). (A) to (D), (G) to (J), (M) to (P), (S) to (V), (Y), (BB), (CC), (EE), (HH), and (II) are the same scale, and (E), (F), (K), (L), (Q), (R), (W), (X), (Z), (AA), (DD), (FF), (GG), and (JJ) are the same scale. Bars = 20 μm in (A) and 50 μm in (E). Arrowheads indicate the plane of the first zygotic cell division ([A], [G], [M], and [S]), the boundary between the apical and basal lineage-derived cells ([B] to [L]), the hypophysis (Y), the apical cell nucleus (BB), or cell planes of the first two longitudinal cell divisions of the apical cell ([EE] and [HH]).
