When I learned biological science at loftier schoolhouse, the textbook clearly stated — as one of the many differences between animal and establish cells — that the Golgi appliance is nowadays in animal cells, whereas it is absent from constitute cells. More than thirty years take passed, and today I hope that most cell biologists know that this is not so. Despite the fact that plant cells have the Golgi, there remains a large difference in our cognition of beast and establish Golgi. Whereas its role as the poly peptide-sorting center in the jail cell has been established by studies on mammalian and yeast cells, our understanding of the establish Golgi has just begun to accumulate. The Golgi Apparatus and the Found Secretory Pathway, published as an event of Annual Plant Reviews, is very timely considering it summarizes not only what we know but too what we do not know about the institute Golgi.

This book, edited past David Robinson (University of Heidelberg, Germany), consists of 14 chapters that have been contributed by many establish Golgi researchers. The offset office is dedicated to a comparison of the structure and organization of the plant Golgi with those of the not-plant Golgi. Affiliate 1, by B. Glick, on the yeast Golgi is a good introduction that serves to refresh our knowledge of Golgi structure and organization. Affiliate 2, past M. Pavelka and D. Robinson, in addition to showing beautiful pictures of the found Golgi that volition appeal to many readers, discusses differences between animal and plant Golgi. The chapters that follow focus on pathways of vesicular trafficking between the endoplasmic reticulum and the Golgi and also betwixt the Golgi and the vacuole, the constitute analogue of the mammalian lysosome. Split chapters describe the role of the Golgi in protein glycosylation and its interaction with the cytoskeleton. Many components involved in trafficking have now been identified in plants and are similar to their non-found counterparts, such as COPI and COPII subunits, Sar/Arf and Rab GTPases, and SNARE molecules. Discussions of these components demonstrate that many aspects of the structure and function of the plant organelle are quite similar to the animal and yeast Golgi, and research on the plant Golgi is quickly catching up.

One unique aspect of the plant Golgi is that its dynamic behaviour is clearly dependent on actin filaments; this is in dissimilarity to the mammalian Golgi, whose localization to the perinuclear region is dependent on microtubules. The found Golgi shows repetitive stop-and-go motion along the actin filament, which suggests a specific role for actin in the Golgi part. Possible interpretations of the significance of the motility of the plant Golgi are discussed in chapter 4 by C. Hawes and colleagues. The office of actin in traffic is likewise important in brute and yeast cells, just it tends to receive less attention than that given to microtubules in mammalian cells. Plant studies might therefore pb the field in this context. Classically, the establish Golgi was studied as a site of polysaccharide synthesis for the supply of cell wall components. It is withal important to understand the plant Golgi from such a standpoint, only this attribute is not emphasized in this volume, probably because the role of Golgi in trafficking is now appreciated as a more attractive question to study. Protein traffic forth the major secretory pathway from the Golgi to the jail cell surface is an important topic, just it has not been studied extensively in plants and is not described in depth in this book. However, an exception is its role in cell plate germination during cytokinesis, which is described in the final chapter.

More than 100 years since Camillo Golgi discovered the apparatus named later on him, it is still a mysterious and fascinating organelle for cell biologists. Its stacked construction continues to attract many researchers, although answers to the question of why and how those cisternae are organized equally stacks still elude researchers. The beauty of the plant Golgi, which is arranged in divide stacks of cisternae, distinct from the unstacked Saccharomyces Golgi and the tangled cluster of the mammalian Golgi, presents a great advantage in probing the secrets of cisternal stacking and will continue to be a target of research for ambitious cell biologists.

This volume provides a proficient opportunity to think about what the Golgi is and what it does, fifty-fifty though it is written from the viewpoints of plant researchers. The level of content is probably appropriate for graduate students but could besides be interesting for undergraduate students, postdoctoral scientists and even the seasoned researcher. I would recommend this volume non just to establish scientists but as well to animal and yeast prison cell biologists who are interested in the Golgi itself and/or in the organization of protein trafficking.
