If the plant cell is described as a miniature factory, then the Golgi apparatus is a major component of the processing machinery that is situated halfway along a key production line -- the secretory pathway. It is difficult to understate the economic importance of the plant secretory pathway, which is composed of the endoplasmic reticulum (ER), Golgi apparatus, vacuoles and an ill-defined prevacuolar/endosomal compartment. As one review stated, “the plant ER virtually feeds the world through the seed storage proteins it synthesises”1. Many of these proteins, especially in the legume crops, pass through the Golgi apparatus for modification, packaging and targeting. Likewise, “there is a lot of extracellular matrix about, and most of it surrounds plant cells”2. Most of the matrix material, cell-wall hemicelluloses, pectins and wall proteins are synthesized in, or pass through, the Golgi apparatus. Therefore, this is certainly an organelle worth studying.
