Download Abiotic Stress-Mediated Sensing and Signaling in Plants: An Omics Perspective Book in PDF, ePub and Kindle
The natural environment for plants is composed of a complex set of abiotic and biotic stresses; plant responses to these stresses are equally complex. Systems biology allows us to identify regulatory hubs in complex networks. It also examines the molecular “parts” (transcripts, proteins and metabolites) of an organism and attempts to combine them into functional networks or models that effectively describe and predict the dynamic activities of that organism in different environments. This book focuses on research advances regarding plant responses to abiotic stresses, from the physiological level to the molecular level. It highlights new insights gained from the integration of omics datasets and identifies remaining gaps in our knowledge, outlining additional focus areas for future crop improvement research. Plants have evolved a wide range of mechanisms for coping with various abiotic stresses. In many crop plants, the molecular mechanisms involved in a single type of stress tolerance have since been identified; however, in order to arrive at a holistic understanding of major and common events concerning abiotic stresses, the signaling pathways involved must also be elucidated. To date several molecules, like transcription factors and kinases, have been identified as promising candidates that are involved in crosstalk between stress signalling pathways. However, there is a need to better understand the tolerance mechanisms for different abiotic stresses by thoroughly grasping the signalling and sensing mechanisms involved. Accordingly, this book covers a range of topics, including the impacts of different abiotic stresses on plants, the molecular mechanisms leading to tolerance for different abiotic stresses, signaling cascades revealing cross-talk among various abiotic stresses, and elucidation of major candidate molecules that may provide abiotic stress tolerance in plants.

Key to the success of plants is their ability to co-ordinate timely responses to stressful environments using intricate intracellular signaling mechanisms. Most, if not all stress signaling cascades register in the nucleus and trigger transcriptional changes that are fundamental for acclimation to stress. Over the last decade it has also become apparent that chloroplasts operate as sensors of prevailing environmental conditions, perceiving abiotic stress and orchestrating the remodelling of the nuclear transcriptome. Nevertheless, these retrograde signals may also have roles beyond bilateral chloroplast-to-nucleus communication when considered in the context of the broader complexity of a cell. Accordingly, identifying the signaling mechanisms and understanding how intracellular signals are translated into expression changes is essential. Throughout a plant's life history, stress also alters subsequent plant responses. As a result, the prospect of epigenetic memory is an evocative subject with exciting research and agronomic possibilities. Yet the more common strategy employed by plants is likely to be recovery and resetting, underpinned by post transcriptional processes and RNA metabolism. This thesis demonstrates the existence of the 'SAL1-PAP-XRN' retrograde signaling pathway in Arabidopsis thaliana (Arabidopsis), providing mechanistic insight into the functions of retrograde signaling during stress. Key to this model is the discovery that the signal is transmitted and interpreted via the nucleotide 3'-phosphoadenosine 5'-phosphate (PAP) and the 5'-3' exoribonucleases (XRNs) respectively. Evidence that key changes in gene expression are mediated by regulation of RNA Polymerase II read-through and activation of downstream genes is also presented, contributing to our understanding of the transmission and specificity of the PAP signal. Beyond a linear retrograde signaling pathway, it is also demonstrated that PAP-signaling is entwined with other components in the complex networks of the eukaryotic cell. In particular, PAP and the XRNs can regulate stomatal responsiveness and in turn drought tolerance, raising the prospect that PAP is a secondary messenger. Indeed, independent of the XRNs, novel PAP binding proteins are identified including NDPKs, CATs and SOS2 implicating PAP in the regulation of Reactive Oxygen Species (ROS), ABA signaling and cellular energy homeostasis. Characterisation of the PAP-XRN regulon highlights to the importance of RNA metabolism in regulating stress responses, raising questions about how cells recover from stress and the contribution of RNA metabolism and post transcriptional processes. It is argued that elucidating the mechanisms of stress recovery is essential for a complete understanding of stress signaling, tolerance and memory. Consequently, Rapid Recovery Gene Silencing (RRGS) is presented as a new mechanism promoting stress recovery. Consistent with this hypothesis, transcripts are turned-over incredibly fast during stress and recovery establishing RRGS as a prevalent phenomenon in Arabidopsis. The generation of the RRGS time course data set establishes a resource for further investigations into how plants balance recovery and memory at the molecular level, comprising comprehensive profiles of the transcriptome, degradome, sRNAome and DNA methylome.

Download Plant Abiotic Stress Book in PDF, ePub and Kindle
Over the past decade, our understanding of plant adaptation to environmental stress has grown considerably. This book focuses on stress caused by the inanimate components of the environment associated with climatic, edaphic and physiographic factors that substantially limit plant growth and survival. Categorically these are abiotic stresses, which include drought, salinity, non-optimal temperatures and poor soil nutrition. Another stress, herbicides, is covered in this book to highlight how plants are impacted by abiotic stress originating from anthropogenic sources. The book also addresses the high degree to which plant responses to quite diverse forms of environmental stress are interconnected, describing the ways in which the plant utilizes and integrates many common signals and subsequent pathways to cope with less favorable conditions. The book is directed at researchers and professionals in plant physiology, cell biology and molecular biology, in both the academic and industrial sectors.

Download Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change Book in PDF, ePub and Kindle
Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals. Dr. Parvaiz is Assistant professor in Botany at A.S.

Download Abiotic Stress Response in Plants Book in PDF, ePub and Kindle
Plants, unlike animals, are sessile. This demands that adverse changes in their environment are quickly recognized, distinguished and responded to with suitable reactions. Drought, heat, cold and salinity are among the major abiotic stresses that adversely affect plant growth and productivity. In general, abiotic stress often causes a series of morphological, physiological, biochemical and molecular changes that unfavorably affect plant growth, development and productivity. Drought, salinity, extreme temperatures (cold and heat) and oxidative stress are often interrelated; these conditions singularly or in combination induce cellular damage. To cope with abiotic stresses, of paramount significance is to understand plant responses to abiotic stresses that disturb the homeostatic equilibrium at cellular and molecular level in order to identify a common mechanism for multiple stress tolerance. This multi authored edited compilation attempts to put forth an all-inclusive biochemical and molecular picture in a systems approach wherein mechanism and adaptation aspects of abiotic stress are dealt with. The chief objective of the book hence is to deliver state of the art information for comprehending the effects of abiotic stress in plants at the cellular level.
