Morphology Defects of the Root Apical Meristem in the gip Double Mutant.

(A) to (E) Roots of gip double mutants.

(F) to (H) Wild-type roots.

(I) to (J) Roots of sesquimutant plants.

Roots are observed in phase contrast ([A], [B], [F], and [G]). Confocal optical median sections are shown in (C) to (E) and (H) to (J). Roots were labeled with Lugol ([B] and [G]), propidium iodide ([C] and [H]), DAPI ([D] and [I]), or immunolabeled with anti-α-tubulin antibodies ([E] and [J]). Chromosomes in (D) and (I) and corresponding spindles ([E] and [J]) of metaphase cells are indicated by arrows. Bars = 50 μm in (A) to (C) and (F) to (H) and 20 μm in (D), (E), (I), and (J).
