Reticulated regions comprise cells with heavily suberized walls. A, Light microcopy images of skin cross sections of smooth and reticulated skin cultivars. Sections were counterstained with Toluidine Blue O. White circles represent regions examined by transmission electron microscopy (TEM) that appear in B and C. B, TEM micrographs of cell walls located within cells of the outermost epidermal layer as indicated in A. C, TEM micrographs of cell walls located within cells of the inner collenchyma as indicated in A. pcw, Primary cell wall; sl, suberin lamellae. Bars = 200 µm (A), 50 nm (B), and 50 nm (C).
