This book was released on 2017-12-28 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Facing stressful conditions imposed by their environment and affecting their growth and their development throughout their life cycle, plants must be able to perceive, to process and to translate different stimuli into adaptive responses. Understanding the organism-coordinated responses involves a fine description of the mechanisms occurring at the cellular and molecular level. A major challenge is also to understand how the large diversity of molecules identified as signals, sensors or effectors could drive a cell to the appropriate plant response and to finally cope with various environmental cues. In this Research Topic we aim to provide an overview of various signaling mechanisms or to present new molecular signals involved in stress response and to demonstrate how basic/fundamental research on cell signaling will help to understand stress responses at the whole plant level.

This book was released on 2016-08-08 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiotic stresses such as high temperature, low-temperature, drought and salinity limit crop productivity worldwide. Understanding plant responses to these stresses is essential for rational engineering of crop plants. In Arabidopsis, the signal transduction pathways for abiotic stresses, light, several phytohormones and pathogenesis have been elucidated. A significant portion of plant genomes (Arabidopsis and rice were mostly studied) encodes for proteins involves in signaling such as receptor, sensors, kinases, phosphatases, transcription factors and transporters/channels. Despite decades of physiological and molecular effort, knowledge pertaining to how plants sense and transduce low and high temperature, low-water availability (drought), water-submergence, microgravity and salinity signals is still a major question for plant biologist. One major constraint hampering our understanding of these signal transduction processes in plants has been the lack or slow pace of application of molecular genomic and genetics knowledge in the form of gene function. 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 not only one gene family but 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. Therefore, in this e-Book, we intend to incorporate the contribution from leading plant biologists to elucidate several aspects of stress signaling by functional genomics approaches.

This book was released on 2016-12-28 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume set takes an in-depth look at stress signaling in plants from a uniquely genomic and proteomic perspective and offers a comprehensive treatise that covers all of the signaling pathways and mechanisms that have been researched so far. Currently, plant diseases, extreme weather caused by climate change, drought and an increase in metals in soil are amongst the major limiting factors of crop production worldwide. They devastate not only the food supply but also the economy of a nation. With global food scarcity in mind, there is an urgent need to develop crop plants with increased stress tolerance so as to meet the global food demands and to preserve the quality of our planet. In order to do this, it is necessary to understand how plants react and adapt to stress from the genomic and proteomic perspective. Plants adapt to stress conditions by activating cascades of molecular mechanisms, which result in alterations in gene expression and synthesis of protective proteins. From the perception of the stimulus to the transduction of the signal, followed by an appropriate cellular response, the plants employ a complex network of primary and secondary messenger molecules. Cells exercise a large number of noticeably distinct signaling pathways to regulate their activity. In order to contend with different environmental adversities, plants have developed a series of mechanisms at the physiological, cellular and molecular levels that respond to stress. Each chapter in this volume provides an in-depth explanation of what we currently know of a particular aspect of stress signaling and where we are heading. Together with the highly successful first volume, Stress Signaling in Plants: Genomics and Proteomics Perspective, Volume 2 covers an important aspect of plant biology for both students and seasoned researchers.

Download or read book Plant Cellular Signaling in Response to Wounding Or Caterpillar Herbivory written by Jamuna Paudel and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Plants have complex signaling networks in response to wounding or caterpillar herbivory. The phytohormone jasmonic acid (JA) mediates the principal plant defense response pathway against caterpillar herbivory. However, some larval species manipulate host plant responses leading to the attenuation of this induced resistance (IR). Although the exact mechanism of the insect subversion of JA-mediated IR is not clearly understood, effectors in the labial salivary secretions of generalist Noctuid caterpillars, such as Spodoptera exigua, are known to activate the salicylic acid (SA)-mediated pathway that antagonize JA responses. Since the caterpillar labial saliva contains significant levels of oxido-reductive enzymes, such as glucose oxidase, it can manipulate cellular redox balance in plant tissues. Similarly, these effectors may activate the ethylene (ET) pathway leading to the modulation of JA pathway. The early cellular response to herbivory by 4th instar S. exigua caterpillars with intact and impaired labial saliva secretions was compared. Labial saliva helps maintain a reductive cellular environment in Arabidopsis thaliana leaves. Labial saliva-specific expression of the marker genes of the JA/ET- and SA-pathways was observed in A. thaliana and that was alleviated in glutathione-compromised pad2.1 or tga2/5/6 mutant plants. Also, caterpillar labial saliva modulated the expression of ET-dependent genes, ERF1 and AtHEL, in a glutathione-independent manner. Therefore, labial saliva of the caterpillar modulates the expression of defense-related genes in SA/NPR1-, glutathione-dependent or ET-, glutathione-independent manner. In comparison, cellular oxidative stress is elevated in the legume Medicago truncatula after caterpillar herbivory. The labial saliva-specific induction of the stress response is alleviated in the ET-insensitive skl mutant suggesting that ET is needed for this response. JA- and JA/ET- pathway marker genes are differentially expressed upon caterpillar herbivory in an ET-independent way. However, labial saliva-specific induction of the SA marker gene and suppression of trypsin inhibitor require ET perception suggesting that caterpillar labial saliva attenuates the JA-pathway by activating the SA pathway and ET modulates these responses. The role of caterpillar labial saliva in the plant defense signaling network was further explored by identifying differences in the post-translational modifications of nuclear proteins. Of the four proteins identified, the transcription factor, AtABF3, showed labial saliva-specific post-translational modification. In Arabidopsis plants subjected to herbivory by caterpillars with impaired labial saliva secretions, AtABF3 is nitrosylated at Cys420 and phosphorylated at Ser431. Since the expression of its downstream target gene, AtWRKY40, is also elevated in this plant, labial saliva-specific post-translational modification may play a role in the modulation of host defense response. As the levels of atmospheric carbon dioxide (CO2) are predicted to double in the next fifty years, the current scenario of plant stress response and, thus, the accumulation of defensive metabolites are expected to alter. Along with the increase of photosynthetic efficiency at elevated CO2, the plant's nitrogen use efficiency will be affected. Thus, plant responses to mechanical wounding at different levels of CO2 (ambient and elevated) and nitrogen fertilization (nitrate-limited and sufficient) were studied. At ambient CO2, mechanical wounding induced a jasmonates (JAs) burst and increased foliar glucosinolate (GSL) levels in Arabidopsis; however, at elevated CO2 conditions, this wound-responsive increase of JAs and GSLs are only observed under nitrate-stress conditions. Although MYB transcription factors that regulate both aliphatic or indole GSL biosynthesis are induced in response to wounding, a general shift from aliphatic GSL to indole GSL is observed in wounded Arabidopis leaves." --

Download or read book Heat Stress Signal Transduction in Plant Cells written by Ahmed Mansour and published by VDM Publishing. This book was released on 2008 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant tolerance to heat stress proved to be entirely dependent on the signa-ling flow of information by which the plant can sense the changes in its surrounding environment and signal its genes to respond by producing special proteins to protect it-self. Any changes or manipulations in this signaling flow of information will presumably lead to a modification in the genetic expression inside the plant cells, consequently, changing plant per-formance. Understanding these signaling events in response to heat may help us to produce heat tolerant plants capable to stand high temperature stress. In the present investigation, the results showed that a heat activated MAP kinase cascade, involving heat activated MAP kinase (HAMK), played an essential role in heat shock gene expression in tobacco BY-2 cells. In order to determine if heat activation of HAMK involved additional pathways of signaling we studied the upstream regulation of HAMK, including membrane fluidization and reorganization of cytoskeleton. The activation of HAMK and accumulation of heat responsive HSFs, HSP70 and HSP27 proteins were used as end-point markers in these experiments. It is concluded that the heat shock response, as measured by HAMK activation and heat shock proteins accu-mulation required PKC activation, membrane fluidization and reorganization of the cytoskeleton. A comparative bioinformatic explanation of similarities between tobacco heat shock genes and their counterparts in different organisms revealed a high degree of evolutionary conservation in the corres-ponding domains, indicating similar function in different species.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental stresses represent the most limiting factors for agricultural productivity. Apart from biotic stress caused by plant pathogens, there are a number of abiotic stresses such as extremes in temperature, drought, salinity, heavy metals and radiation which all have detrimental effects on plant growth and yield. However, certain plant species and ecotypes have developed various mechanisms to adapt to such stress conditions. Recent advances in the understanding of these abiotic stress responses provided the impetus for compiling up-to-date reviews discussing all relevant topics in abiotic stress signaling of plants in a single volume. Topical reviews were prepared by selected experts and contain an introduction, discussion of the state of the art and important future tasks of the particular fields.

Download or read book Salt and Drought Stress Tolerance in Plants written by Mirza Hasanuzzaman and published by Springer Nature. This book was released on 2020-04-10 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents various aspects of salt and drought stress signaling in crops, combining physiological, biochemical, and molecular studies. Salt and drought stress are two major constraints on crop production worldwide. Plants possess several mechanisms to cope with the adverse effects of salt and drought. Among these mechanisms, stress signaling is very important, because it integrates and regulates nuclear gene expression and other cellular activities, which can help to restore cellular homeostasis. Accordingly, understanding the signaling cascades will help plant biologists to grasp the tolerance mechanisms that allow breeders to develop tolerant crop varieties. This book is an essential resource for researchers and graduate students working on salt and drought stress physiology and plant breeding.

Download or read book Signaling in the Plant General Stress Response written by Marta Bjornson and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: All living things must adapt and respond to stresses, both internal and external. These responses must be coordinated from the organelle to the organism level, on timescales from seconds to months, to achieve a successful outcome. In my dissertation research I studied the regulation, interplay, and overlap of stress signaling networks, primarily utilizing the general stress response (GSR) as a model: a central signaling pathway key in adapting to imposed stresses. First, I conducted forward and chemical genetic screens using reporter plants expressing luciferase under the control of a functional GSR cis element, the rapid stress response element (4xRSRE:LUC). These allowed me to identify a role for mitogen activated protein kinase (MAPK) signaling in regulation of both the amplitude and timing of general stress responses. A role for MAPK signaling in activation of diverse stress responses as well as developmental processes has been demonstrated, but my work showing MAPK regulation of timing of the plant GSR identified a new axis along which these signaling cascades control stress responses. I expanded this result to publish a protocol for the chemical genetic screening procedure as used in this discovery. In a second approach for understanding plant stress signaling, I also studied interactions among signaling pathways affecting the GSR, including both stress-activated and primarily non-stress-associated pathways. Among stress-independent pathways, I selected brassinosteroid signaling; this plant hormone is primarily associated with growth, but has published interactions with abiotic stress tolerance and inhibition of microbe recognition. Surprisingly, I found that brassinosteroid signaling, independent of interactions with tested stress-associated hormones exerted a positive effect on abiotic (wound) induced GSR, but a negative effect on biotic (pathogen) induced GSR. This result, held up in long-term stress adaptation, supports the notion that growth vs. stress response signaling consists not of simple antagonism, but fine-tuning depending on the nature of the relative pathways. Altogether, my work has revealed novel interaction and regulation points in stress signaling networks, advancing our understanding of the continuous adaptation to environmental conditions that is key for plant survival.
