The plant Golgi apparatus plays a central role in the synthesis of cell wall material and the modification and sorting of proteins destined for the cell surface and vacuoles. Earlier perceptions of this organelle were shaped by static transmission electron micrographs and by its biosynthetic functions. However, it has become increasingly clear that many Golgi activities can only be understood in the context of its dynamic organization. Significant new insights have been gained recently into the molecules that mediate this dynamic behavior, and how this machinery differs between plants and animals or yeast. Most notable is the discovery that plant Golgi stacks can actively move through the cytoplasm along actin filaments, an observation that has major implications for trafficking to, through and from this organelle.
