In a presentation to the Linnean Society of London in November 1831, the Scottish botanist Robert Brown (perhaps better known for his discovery of Brownian motion) mentioned almost as an afterthought that in orchid epidermal cells, a single “circular areola” could be seen, a “nucleus of the cell as perhaps it might be termed.” Thus, the term “nucleus” (from Latin nucleus or nuculeus, “little nut” or kernel) was born for the compartment of the eukaryotic cell that contains the maj- ity of genetic information. One hundred and seventy-seven years later, we know that the nucleus is the site where genetic information is stored in the form of DNA, and where it is protected from damage, duplicated, divided, recombined, repaired, and “expressed.” For the latter, the genetic information is faithfully transcribed from DNA to RNA, then released from the nucleus into the surrounding cytoplasm. Most likely translated into polypeptide chains, the information re-enters the nucleus in the form of diverse proteins that function in the processes listed above.

Plant Cells and Their Organelles provides a comprehensive overview of the structure and function of plant organelles. The text focuses on subcellular organelles while also providing relevant background on plant cells, tissues and organs. Coverage of the latest methods of light and electron microscopy and modern biochemical procedures for the isolation and identification of organelles help to provide a thorough and up-to-date companion text to the field of plant cell and subcellular biology. The book is designed as an advanced text for upper-level undergraduate and graduate students with student-friendly diagrams and clear explanations.

Plant Cell Organelles contains the proceedings of the Phytochemical Group Symposium held in London on April 10-12, 1967. Contributors explore most of the ideas concerning the structure, biochemistry, and function of the nuclei, chloroplasts, mitochondria, vacuoles, and other organelles of plant cells. This book is organized into 13 chapters and begins with an overview of the enzymology of plant cell organelles and the localization of enzymes using cytochemical techniques. The text then discusses the structure of the nuclear envelope, chromosomes, and nucleolus, along with chromosome sequestration and replication. The next chapters focus on the structure and function of the mitochondria of higher plant cells, biogenesis in yeast, carbon pathways, and energy transfer function. The book also considers the chloroplast, the endoplasmic reticulum, the Golgi bodies, and the microtubules. The final chapters discuss protein synthesis in cell organelles; polysomes in plant tissues; and lysosomes and spherosomes in plant cells. This book is a valuable source of information for postgraduate workers, although much of the material could be used in undergraduate courses.

This timely volume brings together expert reviews of the recent significant advances in our knowledge and understanding of the organisation of the higher plant nucleus, and in particular in the relationship between nuclear organisation and the regulation of gene expression. Rapid progress has been made in a number of key areas over the last five years, including description and characterization of proteins of the nuclear envelope and nuclear pore complex, novel insights into nucleoskeletal structures, as well as developments related to chromatin organization, function and gene expression. These advances open the way for new research into areas such as stress tolerance, plant-pathogen interactions and ultimately crop improvement and food security. Continued research into plant nuclear structure, genome architecture and gene regulation also enriches our understanding of the origin and evolution of the nucleus and its envelope. Edited by world-class researchers in plant cell biology, and comprising contributions from internationally-renowned academics, this latest volume in the prestigious Annual Plant Reviews series brings together a wealth of knowledge in the burgeoning field of plant nuclear structure and genetics. Annual Plant Reviews, Volume 46: Plant Nuclear Structure, Genome Architecture and Gene Regulation is a vital resource for advanced students, researchers and professionals in plant science and related disciplines. Libraries in all research establishments where plant science, biochemistry, molecular biology, genetics and genomics and agricultural science are taught and studied will find this excellent volume an essential addition to their shelf.

Research on the nuclear matrix has grown enormously since Bereney and Coffey first reported its isolation and initial characterization in 1974. Since then, more than 1000 papers have been published on the subject by numerous workers around the world. This is the first book devoted to reviewing the major developments in this growing field. Key Features * The chapters cover a variety of topics, including: * Isolation of the nuclear matrix * Nuclear structure morphology in situ * Structural domains of the nuclear matrix and its components * Biochemistry and molecular biology of the matrix proteins and associated DNA and RNA * Functional properties associated with the nuclear matrix * DNA replication * Transcription * RNA splicing * Transcription regulation * Intranuclear and nucleocytoplasmic transport and targeting * Cell cycle regulation
