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 Protein Phosphatases and Stress Management in Plants written by Girdhar K. Pandey and published by Springer Nature. This book was released on 2020-09-26 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The regulation of the phosphorylation/dephosphorylation process, resulting in “cellular switches” that monitor normal plant physiology, growth and development, has immense potential in crop systems. With much of the information in the nascent stages, coming largely from Arabidopsis and rice particularly, the use of cell biology, genetic screens, biochemical approaches aided by an omics approach should help unravel the detail functional information available about signaling pathways in plants. The regulation could be exploited to develop crop varieties better equipped to handle changing environments and enhance agricultural productivity. In the post-genomic era, one of the major challenges is investigation and understanding of multiple genes and gene families regulating a particular physiological and developmental aspect of plant life cycle. One of the important physiological processes is regulation of stress response, which leads to adaptation or adjustment in response to adverse stimuli. With the holistic understanding of the signaling pathways involving phosphatases, one gene family or multiple genes or gene families, plant biologist can lay a foundation for designing and generating future crops, which can withstand the higher degree of environmental stresses. Especially abiotic stresses, which are the major cause of crop loss throughout the world without losing crop yield and productivity. This book incorporates the contributions from leading plant biologists in the field of stress-mediated dephosphorylation by phosphatases as an important task to elucidate the aspects of stress signaling by functional genomic approaches.
Download or read book Ecoepigenetics in Clonal and Inbreeding Plants Transgenerational Adaptation and Environmental Variation written by Bi-Cheng Dong and published by Frontiers Media SA. This book was released on 2019-10-15 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clonality is widespread in plant species, and clonal plants often have a broad geographic range and long lifespan. Clonality can maintain high fitness in the short term, but vegetative reproduction is commonly considered to preclude adaptation to changing conditions. However, an increasing body of empirical and theoretical evidence suggests that epigenetic modifications such as DNA methylation can provide an alternative to gene-driven evolution through natural selection and allow clonal plants to maintain fitness in the long term. To deepen our understanding of clonal ecology, this collection of research papers and reviews focuses on how epigenetic regulation can encode phenotypic plasticity and contribute to the rapid adaptation of clonal plants to accelerating global and regional environmental changes.
Download or read book Epigenetic Modifications in Plants Under Abiotic Stress written by Garima Singroha and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants face a plethora of biotic and abiotic stresses ranging from extreme temperatures to salinity, drought, nutritional deficiencies, chemical toxicity, and pathogen attacks. As a consequence, plants have acquired several sophisticated regulatory mechanisms that allow them to cope with such adverse conditions. Epigenetic regulation plays a key role in the mechanisms of plant response to the environment, without altering DNA sequences. Epigenetics refers to heritable alterations in chromatin architecture that do not involve changes in the underlying DNA sequence but alter gene expression through DNA methylation or histone modifications. The epigenetic regulation of the plant genome is a highly dynamic process that fine-tunes the expression of a pertinent set of genes under certain environmental or developmental conditions. Over the past two decades rapid advancements in the field of high throughput sequencing unveil epigenetic information at genome wide level in various plant species. In view of the adverse effects of global climatic change, utilizing epigenetic differences for developing improved crop varieties is of paramount importance.

Unlocking the molecular underpinnings of these processes shows great promise for the development of new plant biotechnologies and improved crop varieties. The topics included in this book emphasize on genomics and functional genomics aspects, to understand the global and whole genome level changes upon particular stress conditions. With the functional genomics tools, the mechanism of phytohormone signaling and their target genes can be defined in a more systematic manner. The integrated analysis of phytohormone signaling under single or multiple stress conditions may prove exceptional to design stress tolerant crop plants in the field conditions. Bringing together the latest advances, as well as the work being done to apply these findings to plant and crop science, Mechanism of Plant Hormone Signaling Under Stress will prove extremely useful to plant and stress biologists, plant biotechnology researchers, as well as students and teachers.

Download or read book Involvement of Epigenetic Regulation in Plant Defence During Biotic Stress written by Jasmine M. Shah and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants being organisms that lack locomotion and vocabulary, they are not privileged to escape and communicate during unfavourable conditions of biotic/abiotic stresses, like their animal counterparts. Therefore, plants have evolved with higher adaptive skills that tune them during unfavourable conditions. In this context, regulation of gene expression plays a crucial role in controlling the cellular pathways required for survival during unfavourable conditions. This chapter is about the epigenetic regulation of plant defence during biotic stress. Researchers have taken various approaches to understand the epigenetic regulation of plant defences and these approaches are described here. Epigenetic regulation also has the potential to be inherited and this phenomenon has aided plants for better adaption. Such reports on transgenerational memory during biotic stress in plants are also compiled. A deeper understanding of epigenetic regulation of defence pathways during biotic stress, and identification of epigenetic marks on the genomes, can aid the development of crop improvement strategies. With the recent advancement in epigenome editing, it should become possible to develop epigenetically improvised plants, devoid of genetic modification.
