Download and read online ebook Changes in Eukaryotic Gene Expression in Response to Environmental Stress write by Burr Atkinson. This book was released on 2012-12-02. Changes in Eukaryotic Gene Expression in Response to Environmental Stress available in PDF, EPUB and Kindle. Changes in Eukaryotic Gene Expression in Response to Environmental Stress focuses on various aspects of eukaryotic cell's response to heat stress (shock) and other stress stimuli. This book is organized into two major sections, encompassing 17 chapters that reflect the emphasis on research utilizing Drosophila, a variety of animal systems, and plants. This book first provides a brief introduction to the organization, sequences, and induction of heat shock proteins and related genes. It then describes the control of transcription during heat shock from the standpoint of molecular biology and evolutionary variations of the mechanisms in organisms with diverse metabolic needs. It goes on to discuss the issue of coordinate and noncoordinate responses of heat shock genes. It presents a model for post-transcriptional regulation on certain aspects of coordinate and noncoordinate regulations. Chapters 6-12 discuss heat shock proteins and genes and the effects of stress on gene expression of sea urchin, avian, and mammalian cells. The second part of the book focuses on the physiological role of heat shock proteins and genes in plants and fungi. It includes a discussion on experimental problems encountered during studies of the mechanisms of inhibition of photosynthesis by unfavorable environmental conditions. The changes in transcription and translation of specific mRNAs in the developing embryo during heat shock at various temperatures are described. The concluding chapters deal with heat shock response in plants, particularly the response in soybeans and maize, covering both physiological and molecular analyses. Research scientists, clinicians, and agriculturists will greatly benefit from the information presented in this book.

Download and read online ebook Stress-Induced Mutagenesis write by David Mittelman. This book was released on 2013-03-12. Stress-Induced Mutagenesis available in PDF, EPUB and Kindle. The discovery of stress-induced mutagenesis has changed ideas about mutation and evolution, and revealed mutagenic programs that differ from standard spontaneous mutagenesis in rapidly proliferating cells. The stress-induced mutations occur during growth-limiting stress, and can include adaptive mutations that allow growth in the otherwise growth-limiting environment. The stress responses increase mutagenesis specifically when cells are maladapted to their environments, i.e. are stressed, potentially accelerating evolution then. The mutation mechanism also includes temporary suspension of post-synthesis mismatch repair, resembling mutagenesis characteristic of some cancers. Stress-induced mutation mechanisms may provide important models for genome instability underlying some cancers and genetic diseases, resistance to chemotherapeutic and antibiotic drugs, pathogenicity of microbes, and many other important evolutionary processes. This book covers pathways of stress-induced mutagenesis in all systems. The principle focus is mammalian systems, but much of what is known of these pathways comes from non-mammalian systems.

Untranslated Gene Regions and Other Non-coding Elements available in PDF, EPUB and Kindle. There is now compelling evidence that the complexity of higher organisms correlates with the relative amount of non-coding RNA rather than the number of protein-coding genes. Previously dismissed as “junk DNA”, it is the non-coding regions of the genome that are responsible for regulation, facilitating complex temporal and spatial gene expression through the combinatorial effect of numerous mechanisms and interactions working together to fine-tune gene expression. The major regions involved in regulation of a particular gene are the 5’ and 3’ untranslated regions and introns. In addition, pervasive transcription of complex genomes produces a variety of non-coding transcripts that interact with these regions and contribute to regulation. This book discusses recent insights into the regulatory roles of the untranslated gene regions and non-coding RNAs in the control of complex gene expression, as well as the implications of this in terms of organism complexity and evolution.

Download and read online ebook Yeast Stress Responses write by Stefan Hohmann. This book was released on 2007-10-23. Yeast Stress Responses available in PDF, EPUB and Kindle. Every cell has developed mechanisms to respond to changes in its environment and to adapt its growth and metabolism to unfavorable conditions. The unicellular eukaryote yeast has long proven as a particularly useful model system for the analysis of cellular stress responses, and the completion of the yeast genome sequence has only added to its power This volume comprehensively reviews both the basic features of the yeast genral stress response and the specific adapations to different stress types (nutrient depletion, osmotic and heat shock as well as salt and oxidative stress). It includes the latest findings in the field and discusses the implications for the analysis of stress response mechanisms in higher eukaryotes as well.
