Plant Golgi stacks. A, Transmission electron micrograph showing a cluster of Golgi stacks in an Arabidopsis root tip cell. Plastids (P), mitochondria (M), and vacuoles (V) are marked. B, Confocal laser scanning micrograph of Arabidopsis root tip cells expressing a Golgi-localized green fluorescent protein. The PM was counterstained. C, ET slice image of a Golgi stack. The cis-side, trans-side, and TGN are labeled. D, ET model of an Arabidopsis Golgi stack associated with the ER. The entire Golgi and TGN are encompassed by a ribosome–ribosome excluding matrix (Golgi matrix). E, ET slice image of a Golgi stack in a root cap border cell. F, ET model of the Golgi in E. Swollen cisternal margins containing mucilage are marked with arrowheads in (E) and (F). Scale bars in (A), (B), (D), (E), and (F): 500 nm. Scale bar in (C): 10 μm.
