When I learned biology at high school, the textbook clearly stated — as ane of the many differences betwixt animal and institute cells — that the Golgi appliance is present in creature cells, whereas it is absent-minded from plant cells. More than 30 years take passed, and today I hope that virtually prison cell biologists know that this is not so. Despite the fact that plant cells have the Golgi, there remains a big divergence in our knowledge of animal and plant Golgi. Whereas its role equally the poly peptide-sorting centre in the jail cell has been established by studies on mammalian and yeast cells, our understanding of the constitute Golgi has merely begun to accumulate. The Golgi Apparatus and the Found Secretory Pathway, published as an issue of Annual Found Reviews, is very timely because it summarizes not only what we know only also what we do not know nearly the establish Golgi.

This volume, edited past David Robinson (Academy of Heidelberg, Germany), consists of xiv capacity that have been contributed past many plant Golgi researchers. The first part is dedicated to a comparison of the structure and organization of the plant Golgi with those of the non-plant Golgi. Affiliate ane, by B. Glick, on the yeast Golgi is a good introduction that serves to refresh our knowledge of Golgi structure and organization. Chapter 2, by M. Pavelka and D. Robinson, in addition to showing beautiful pictures of the plant Golgi that volition appeal to many readers, discusses differences between animal and found Golgi. The capacity that follow focus on pathways of vesicular trafficking between the endoplasmic reticulum and the Golgi and besides between the Golgi and the vacuole, the plant counterpart of the mammalian lysosome. Separate chapters describe the role of the Golgi in protein glycosylation and its interaction with the cytoskeleton. Many components involved in trafficking accept now been identified in plants and are similar to their non-plant 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 inquiry on the plant Golgi is quickly catching upwardly.

One unique attribute of the plant Golgi is that its dynamic behaviour is conspicuously 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 finish-and-go movement along the actin filament, which suggests a specific role for actin in the Golgi function. Possible interpretations of the significance of the move of the found Golgi are discussed in chapter 4 by C. Hawes and colleagues. The role of actin in traffic is too of import in creature and yeast cells, simply it tends to receive less attending than that given to microtubules in mammalian cells. Plant studies might therefore pb the field in this context. Classically, the plant Golgi was studied as a site of polysaccharide synthesis for the supply of jail cell wall components. It is even so important to understand the plant Golgi from such a standpoint, but this attribute is not emphasized in this book, probably because the role of Golgi in trafficking is now appreciated every bit a more attractive question to written report. Poly peptide traffic along the major secretory pathway from the Golgi to the cell surface is an important topic, just it has not been studied extensively in plants and is not described in depth in this book. Nonetheless, an exception is its part in cell plate formation during cytokinesis, which is described in the terminal affiliate.

More than than 100 years since Camillo Golgi discovered the apparatus named after him, it is even so 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 as stacks nonetheless elude researchers. The dazzler of the constitute 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 bully advantage in probing the secrets of cisternal stacking and volition continue to be a target of research for ambitious cell biologists.

This book provides a good opportunity to recollect about what the Golgi is and what it does, fifty-fifty though it is written from the viewpoints of constitute researchers. The level of content is probably appropriate for graduate students just could likewise be interesting for undergraduate students, postdoctoral scientists and even the seasoned researcher. I would recommend this book not only to constitute scientists just also to creature and yeast cell biologists who are interested in the Golgi itself and/or in the organization of protein trafficking.
