Available in PDF, EPUB and Kindle. Book excerpt: Senescence and Aging in Plants reviews the state of knowledge in the processes involved in plant senescence and aging. The book begins by discussing the emergence of senescence as a concept; experimental analysis of senescence; and patterns of senescence. It then examines membrane deterioration during senescence; photosynthesis in relation to leaf senescence; senescence of detached plant organs; changing patterns of nucleic acid and protein synthesis during senescence; and degradative and associated assimilatory aspects of nitrogen removal. This is followed by chapters on aspects of ethylene that may impinge upon its role in promoting senescence of higher plants; the role of cytokinins in plant senescence; the promoters and retardants of senescence; and the role of calcium in plant senescence. The concept of whole plant senescence is discussed, which can be subdivided into patterns, correlative controls, cessation of vegetative growth, declining assimilatory processes, assimilate partitioning, and hormonal controls. The final chapters cover the deterioration of cellular membranes during the plant aging process and seed aging.

Available in PDF, EPUB and Kindle. Book excerpt: The scientific and economic significance of plant senescence means that much effort has been made to understand the processes involved and to devise means of manipulating them agriculturally. During the past few years there has been considerable progress in this regard, especially in the molecular, genetic and genomic aspects. Senescence has a tremendous impact on agriculture. For example, leaf senescence limits crop yield and biomass production, and contributes substantially to postharvest loss in vegetable and ornamental crops during transportation, storage and on shelves. In addition, proteins, antioxidants and other nutritional compounds are degraded during senescence. Senescing tissues also become more susceptible to pathogen infection, and some of the pathogens may produce toxins, rendering food unsafe. Mitotic senescence may also determine sizes of leaves, fruits and whole plants. This volume summarizes recent progresses in the physiology, biochemistry, cell biology, molecular biology, genomics, proteomics, and biotechnology of plant senescence. Beginning with a chapter on senescence-related terminology and our current knowledge of mitotic senescence in plants (a less well-studied area), the book focuses on post-mitotic senescence, and includes chapters addressing the senescence of leaves, flowers and fruits. Later chapters examine the development of various new biotechnologies for manipulating the senescence processes of fruit and leaves, some of which are approaching commercialization. The book is directed at researchers and professionals in plant molecular genetics, physiology and biochemistry.
Download or read book Stress Signaling in Plants Genomics and Proteomics Perspective Volume 2 written by Maryam Sarwat and published by Springer. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent methods for Systems Genetics (SG) data analysis, applying them to a suite of simulated SG benchmark datasets. Each of the chapter authors received the same datasets to evaluate the performance of their method to better understand which algorithms are most useful for obtaining reliable models from SG datasets. The knowledge gained from this benchmarking study will ultimately allow these algorithms to be used with confidence for SG studies e.g. of complex human diseases or food crop improvement. The book is primarily intended for researchers with a background in the life sciences, not for computer scientists or statisticians.
Download or read book Genetic Analysis of K4 SURG Transcription Factors During Leaf Senescence in Arabidopsis Thaliana written by Md. Sharif Hasan and published by . This book was released on 2017 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Leaf senescence is the final stage of leaf development that is characterized by highly regulated genetic programs. This process involves recycling and recovery of the nutrients and relocating them to the developing part of the plant for high yield of fruits and grains. In this project we focused on four genes (WRKY45, NAC084, NAC100 and undesignated NAC) that coded for either WRKY or NAC transcription factors to determine their effects on leaf senescence by assaying both chlorophyll and protein levels, analyzing chlorophyll and protein degradation rates and quantifying the transcript abundance of senescence marker genes, WRKY75, NIT2, DGR2 and Lhcb2. wrky45 mutants showed early senescence. We observed lower chlorophyll level and faster chlorophyll degradation rate that was supported by the real time qPCR data showing greater upregulation in SURG and downregulation in SDRG. These findings suggest that WRKY45 gene has a negative regulatory effect in WT plants. In contrast, nac084 mutant showed delayed senescence. We found higher chlorophyll level and slower chlorophyll degradation rate that was supported by the real time qPCR data showing downregulation of SURG and upregulation of SDRG. These findings suggest a positive regulatory effect of NAC084 in senescence. NAC100 did not show any significant changes in leaf senescence. On the other hand, undesignated NAC behaved like a normal gene as the und-nac-1 mutant was not affected by a T-DNA insertion and may not have disrupted gene expression.
Download or read book Post Transcriptional Control of Gene Expression in Plants written by Witold Filipowicz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent volume of this series (Signals and Signal Transduction Pathways in Plants (K. Palme, ed.) Plant Molecular Biology 26, 1237-1679) described the relay races by which signals are transported in plants from the sites of stimuli to the gene expression machinery of the cell. Part of this machinery, the transcription apparatus, has been well studied in the last two decades, and many important mechanisms controlling gene expression at the transcriptional level have been elucidated. However, control of gene expression is by no means complete once the RNA has been produced. Important regulatory devices determine the maturation and usage of mRNA and the fate of its translation product. Post-transcriptional regulation is especially important for generating a fast response to environmental and intracellular signals. This book summarizes recent progress in the area of post-transcriptional regulation of gene expression in plants. 18 chapters of the book address problems of RNA processing and stability, regulation of translation, protein folding and degradation, as well as intracellular and cell-to-cell transport of proteins and nucleic acids. Several chapters are devoted to the processes taking place in plant organelles.
