This volume provides a comprehensive collection of protocols that can be used to study plant chromatin structure and composition. Chapters divided into three sections detail the profiling of chromatin features in relation to epigenetic regulation, investigate the interaction between chromatin modifications and gene regulation, and explore the 3D spatial organization of the chromatin inside the nucleus. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Plant Chromatin Dynamics: Methods and Protocols aims to ensure successful results in the further study of this vital field.

Chromatin Regulation and Dynamics integrates knowledge on the dynamic regulation of primary chromatin fiber with the 3D nuclear architecture, then connects related processes to circadian regulation of cellular metabolic states, representing a paradigm of adaptation to environmental changes. The final chapters discuss the many ways chromatin dynamics can synergize to fundamentally contribute to the development of complex diseases. Chromatin dynamics, which is strategically positioned at the gene-environment interface, is at the core of disease development. As such, Chromatin Regulation and Dynamics, part of the Translational Epigenetics series, facilitates the flow of information between research areas such as chromatin regulation, developmental biology, and epidemiology by focusing on recent findings of the fast-moving field of chromatin regulation. Presents and discusses novel principles of chromatin regulation and dynamics with a cross-disciplinary perspective Promotes crosstalk between basic sciences and their applications in medicine Provides a framework for future studies on complex diseases by integrating various aspects of chromatin biology with cellular metabolic states, with an emphasis on the dynamic nature of chromatin and stochastic principles Integrates knowledge on the dynamic regulation of primary chromatin fiber with 3D nuclear architecture, then connects related processes to circadian regulation of cellular metabolic states, representing a paradigm of adaptation to environmental changes

This special topic issue is divided into two sections, and each of them presents its own set of reviews and research articles. 'Organization and dynamics of plant chromatin' is the title of the first section which explores an ample variety of subjects. The topics covered include the structure and function of meiotic chromosomes, open chromatin, nuclear architecture and chromatin dynamics and proteomic analysis of plant cell nuclei. 'Epigenetic modification of plant chromatin' is the title of the second section. This provides a broad array of studies on various plant species and epigenetic modification of plant chromatin. This novel approach represents one of the most interesting developments in research in the field of modern cytogenetics. 'Organization, Dynamics and Modification of Chromatin in Plants' is of particular interest to researchers and teachers in genetics and cytology.

Biological processes that replicate, preserve and use the genetic information encoded in DNA must operate in the context of chromatin, a highly organized complex of DNA and proteins. These proteins do not merely package the DNA in the tiny volume of the nucleus, but impart the structure the ability to change according to the requirements of the specific process the DNA is involved in. Moreover, chromatin structure is used by the cell to control the activity of DNA. In this volume the basics of chromatin structure and dynamics are presented by established experts in the field.

An early view of eukaryotic chromosomes was that of static structures, which stored DNA not in use within a given cell type. It was thought that packaging of DNA into higher levels of chromatin structure would suffice to repress gene expression and that the challenge to the cell would be to rescue specific sequences from these structures. The exten sive packaging of inactive DNA was considered the primary difference between eukaryotic and prokaryotic genomes and except for that point both would be similarly regulated by cis-acting sequences and trans acting factors. Our view of eukaryotic chromosomes has evolved dra matically over the last decade. The picture of chromosomes that is emerging is that of dynamic breathing organelles actively regulating the flow of genetic information from the genome. Indeed chromatin is so fluid that even maintaining gene quiescence is an active process and is tightly regulated. Chromatin dynamics is a consequence of protein complexes that modify histones, remove histone modifications, mobi lize nucleosomes or stabilize nucleosomes. Awide variety of such com plexes have now been described. Some are abundant and may play glo bal roles in chromosome fluidity and function. Others are more rare and specialized for specific functions at discreet loci. Moreover, several complexes share biochemical activities and genetic studies suggest overlapping functions in vivo. Many components of these complexes were first revealed in genetic screens, while others were discovered by novel cell biological or biochemical approaches.

This eBook focuses on current progress in understanding the role of chromatin structure, its modifications and remodeling in developmental and physiological processes. Eukaryotic genomes are packed into the supramolecular nucleoprotein structure of chromatin. Therefore, our understanding of processes such as DNA replication and repair, transcription, and cell differentiation requires an understanding of the structure and function of chromatin. While the nucleotide sequence of the DNA component of chromatin constitutes the genetic material of the cell, the other chromatin components (and also modifications of bases in the DNA itself) participate in so-called epigenetic processes. These processes are essential, e.g., in ontogenesis or adaptation to environmental changes. Therefore, epigenetics is particularly important (and elaborated) in plants that show a high developmental plasticity and, as sessile organisms, display an enormous capacity to cope with environmental stress. In these processes, epigenetic mechanisms show a crosstalk with plant signaling pathways mediated by phytohormones and redox components. You are welcome to read examples of current research and review articles in this hot research topic.
