Summary of patterns observed during early ligule development. (A) Cartoon of maize leaf primordium and proximodistal zones. Black box indicates the area studied. (B-E) Patterns in epidermal topography are shown using representative confocal micrograph projections and cartoons. Proximodistal patterns in cell wall IM, PIN1a-YFP signal and the position/frequency of periclinal divisions are shown using color gradients. Panels show early PLB stage (B), PLB stage (C), late PLB stage (D) and early fringe stage (E). Scale bars: 15 μm.
