Available in PDF, EPUB and Kindle. Book excerpt: Cells face a barrage of internal and external stresses that could inflict severe damage on the molecules essential for life. To cope with environmental challenges, cells have evolved complex stress responses. Posttranslational protein modifications, including ubiquitin-like modifiers, are a major means by through which cells respond to these changing environmental conditions. This thesis explores how the small ubiquitin-like modifier (SUMO) is used to modulate cellular outcomes via transcription, with a particular focus on cellular contexts that require rapid transcriptional changes, such as stress. I present evidence from studies in Saccharomyces cerevisiae that SUMO can be inhibitory to transcription both through direct signaling and non-signaling modes of function. First, I present my findings that SUMO can act as a signal to inhibit the transcription activation potential of a predicted SUMO-targeted ubiquitin ligase that also functions in transcriptional silencing. I discuss potential models for how SUMO might direct switching between transcriptional silencing and activation functions of this protein. Second, discuss independent work demonstrating that SUMO, a highly soluble protein, can promote transcriptional repression in a non-signaling manner by solubilizing transcriptional regulators at risk of misfolding during stress. I show that during hyperosmotic stress, two members of a transcriptional corepressor complex are rapidly and transiently SUMO-modified, and loss of this sumoylation drives accumulation of these proteins into inclusions and correlates with widespread loss of transcriptional repression. Finally, I discuss the broader implications of the signaling and non-signaling functions of SUMO in transcriptional modulation, with a focus on SUMO's potential to drive the adaptive potential of cells in changing environmental contexts.

Download or read book Abiotic Stress Response in Plants written by Arun Shanker and published by BoD – Books on Demand. This book was released on 2011-08-29 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Lipid metabolism in mammals written by Fred Snyder and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade we have witnessed a vast expansion in our knowl edge of lipid metabolism, especially for mammalian tissues. One obvious conclusion arising from these studies is that no single overall scheme of lipid metabolism can be classed as distinctly characteristic of all mamma lian organs. Although certain synthetic and degradative lipid pathways are similar in a variety of organs, I have been impressed by the notable exceptions. I was motivated to organize this work on Lipid Metabolism in Mammals because of the lack of a single reference source containing a comparative organ approach to lipid metabolism in mammals that empha sizes the uniqueness of pathways in the various organs of the body. Because of the escalation in lipid research, I also feel strongly that there is an urgent need for an updated concise account of this field. The group of authors for the chapters in the two volumes of Lipid Metabolism in Mammals were selected for their expertise and personal experience with the lipid metabolism of the organs or blood constituents that are the subjects of the chapters. Sufficient leeway has been given each author to approach the subject matter from a personal viewpoint. How ever, the overall direction of each chapter has been slanted to emphasize the similarities and differences in lipid metabolism among organ systems. The introductory chapter on general pathways provides a convenient refer ence to illustrations of specific reaction sequences that are well established and that occur in a number of organs.

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.

Download or read book Membrane Biogenesis written by Jos A.F. Op den Kamp and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many individual aspects of the dynamics and assembly of biological membranes have been studied in great detail. Cell biological approaches, advanced genetics, biophysics and biochemistry have greatly contributed to an increase in our knowledge in this field.lt is obvious however, that the three major membrane constituents - lipids, proteins and carbohydrates- are studied, in most cases separately and that a coherent overview of the various aspects of membrane biogenesis is not readily available. The NATO Advanced Study Institute on "New Perspectives in the Dynamics of Assembly of Biomembranes" intended to provide such an overview: it was set up to teach students and specialists the achievements obtained in the various research areas and to try and integrate the numerous aspects of membrane assembly into a coherent framework. The articles in here reflect this. Statting with detailed contributions on phospholipid structure, dynamics, organization and biogenesis, an up to date overview of the basic, lipidic backbone of biomembranes is given. Extensive progress is made in the research on membrane protein biosynthesis. In particular the post- and co-translational modification processes of proteins, the mechanisms of protein translocation and the sorting mechanisms which are necessary to direct proteins to their final, intra - or extracellular destination have been characterized in detail. Modern genetic approaches were indispensable in this research area: gene cloning, hybrid protein construction, site directed mutagenesis and sequencing techniques elucidated many functional aspects of specific nucleic acid and amino acid sequences.
