Book Synopsis Epigenetic Memory and Control in Plants by : Gideon Grafi
Download or read book Epigenetic Memory and Control in Plants written by Gideon Grafi and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetics commonly acts at the chromatin level modulating its structure and consequently its function in gene expression and as such plays a critical role in plant response to internal and external cues. This book highlights recent advances in our understanding of epigenetic mechanisms as a major determinant through which internal and external signals, such as those occurring during hybridization, flowering time, reproduction and response to stress, communicate with plant cells to bring about activation of multiple nuclear processes and consequently plant growth and development. The outcome of these processes may persist for generations long after the initial cues have expired and may contribute to plant evolution.
Book Synopsis Epigenetics in Plants of Agronomic Importance: Fundamentals and Applications by : Raúl Alvarez-Venegas
Download or read book Epigenetics in Plants of Agronomic Importance: Fundamentals and Applications written by Raúl Alvarez-Venegas and published by Springer. This book was released on 2014-07-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, chromatin remodelling has emerged as an important regulator of gene expression and plant defense. This book provides a detailed understanding of the epigenetic mechanisms involved in plants of agronomic importance. The information presented here is significant because it is expected to provide the knowledge needed to develop in the future treatments to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases and to increase crop productivity. New approaches of this kind and the development of new technologies will certainly increase our knowledge of currently known post-translational modifications and facilitate the understanding of their roles in, for example, host-pathogen interactions and crop productivity. Furthermore, we provide important insight on how the plant epigenome changes in response to developmental or environmental stimuli, how chromatin modifications are established and maintained, to which degree they are used throughout the genome, and how chromatin modifications influence each another.

This second edition provides detailed information on the epigenetic mechanisms in plants, illustrating the value of this research in plants of agronomic importance. It examines recent advances regarding plants’ epigenetic regulation in response to abiotic and biotic types of stress; the epigenetic basis of plant immunity; evolution and functions of plant histones; epigenetic variation and plant breeding; and epigenome editing and crop improvement. The content is intended to promote the development of future biotechnologies to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases, and to increase crop productivity. The development of new fields, like epigenome editing and RNA epigenetics, will certainly improve our understanding of currently known epigenetic modifications and their roles in e.g. host-pathogen interactions, crop productivity, and in response to environmental stimuli. This volume contains twelve new/revised chapters, written by an international team of experts on plant epigenetics, and addresses the needs of researchers and professionals in the fields of agronomics, crop breeding, epigenetics, plant biochemistry, plant developmental biology, and related disciplines.
Book Synopsis Epigenetic Modifications Associated with Abiotic and Biotic Stresses in Plants: An Implication for Understanding Plant Evolution by : Mahmoud W. Yaish
Download or read book Epigenetic Modifications Associated with Abiotic and Biotic Stresses in Plants: An Implication for Understanding Plant Evolution written by Mahmoud W. Yaish and published by Frontiers Media SA. This book was released on 2018-01-16 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alterations in gene expression are essential during growth and development phases and when plants are exposed to environmental challenges. Stress conditions induce gene expression modifications, which are associated with changes in the biochemical and physiological processes that help plants to avoid or reduce potential damage resulting from these stresses. After exposure to stress, surviving plants tend to flower earlier than normal and therefore transfer the accumulated epigenetic information to their progenies, given that seeds, where this information is stored, are formed at a later stage of plant development. DNA methylation is correlated with expression repression. Likewise, miRNA produced in the cell can reduce the transcript abundance or even prevent translation of mRNA. However, histone modulation, such as histone acetylation, methylation, and ubiquitination, can show distinct effects on gene expression. These alterations can be inherited, especially if the plants are consistently exposed to a particular environmental stress. Retrotransposons and retroviruses are foreign movable DNA elements that play an important role in plant evolution. Recent studies have shown that epigenetic alterations control the movement and the expression of genes harbored within these elements. These epigenetic modifications have an impact on the morphology, and biotic and abiotic tolerance in the subsequent generations because they can be inherited through the transgenerational memory in plants. Therefore, epigenetic modifications, including DNA methylation, histone modifications, and small RNA interference, serve not only to alter gene expression but also may enhance the evolutionary process in eukaryotes. In this E-book, original research and review articles that cover issues related to the role of DNA methylation, histone modifications, and small RNA in plant transgenerational epigenetic memory were published. The knowledge published on this topic may add new insight on the involvement of epigenetic factors in natural selection and environmental adaptation. This information may also help to generate a modeling system to study the epigenetic role in evolution.

Download or read book Annual Plant Reviews, Plant Epigenetics written by Peter Meyer and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the discovery of RNAi pathways and the histone code, epigenetics has become a popular and fast evolving research topic. Plant science has made a number of elementary contributions to this field, and the common elements of epigenetic systems have linked research groups interested in plant, fungal and animal systems. This volume provides a comprehensive overview epigenetic mechanisms and biological processes in plants, illustrating the wider relevance of this research to work in other plant science areas and on non-plant systems. It discusses recent advances in our knowledge of basic mechanisms and molecular components that control transcriptional and post-transcriptional silencing, an understanding of which is essential for plant researchers who use transgenic lines for stable expression of a recombinant construct or for targeted inactivation of an endogenous gene. These aspects should be of special interest to the agricultural industry. The volume illustrates the relevance of epigenetic control systems to gene regulation and plant development, examining paramutation, genomic imprinting and microRNA-based gene regulation mechanisms. Finally, it demonstrates the significance of epigenetic systems to viral defence and genome organisation. The volume is directed at researchers and professionals in plant molecular genetics, plant biochemistry and plant developmental biology.

Book Synopsis Memory and Learning in Plants by : Frantisek Baluska
Download or read book Memory and Learning in Plants written by Frantisek Baluska and published by Springer. This book was released on 2018-04-23 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assembles recent research on memory and learning in plants. Organisms that share a capability to store information about experiences in the past have an actively generated background resource on which they can compare and evaluate coming experiences in order to react faster or even better. This is an essential tool for all adaptation purposes. Such memory/learning skills can be found from bacteria up to fungi, animals and plants, although until recently it had been mentioned only as capabilities of higher animals. With the rise of epigenetics the context dependent marking of experiences on the genetic level is an essential perspective to understand memory and learning in organisms. Plants are highly sensitive organisms that actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behavior accordingly. The book will guide scientists in further investigations on these skills of plant behavior and on how plants mediate signaling processes between themselves and the environment in memory and learning processes.

Book excerpt: The discovery of DNA as the genetic material brought great hope to scientists all over the world. It was believed that many of the lingering questions in genetics and the mechanisms of heredity would fnally be answered. However, as often is the case in science, more qu- tions arose out of this discovery. What defnes a gene? What are the mechanisms of gene regulation? Further discovery and technological innovations brought about sequencing techniques that allowed the study of complete genomes from many organisms, including Arabidopsis and humans. Despite all the excitement surrounding these technologies, many features of the genome remained unclear. Peculiar characteristics in genome composition such as signifcant redundancy consisting of many repetitive elements and noncoding sequences, active transcriptional units with no protein product, and unusual sequences in promoter regions added to the mysteries of genetic make-up and gene regulation. Indeed, the more we discovered about the genome, the more diffcult it became to understand the complexity of cellular function and regulation. Out of the study of the intricacies of the genome and gene regulation, arose a new science that was independent of actual DNA changes, but critical in maintaining gene regulation and genetic stability. Epigenetics, literally translated as “above genetics,” is the science that describes the mechanisms of heritable changes in gene regulation that does not involve modifcations of DNA sequence. These changes may last through somatic cell division and, in some cases, throughout multiple generations.
