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.

Download or read book Post transcriptional Control of Gene Expression written by Celine Sin and published by . This book was released on 2016 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene expression describes the process of making functional gene products (e.g. proteins or special RNAs) from instructions encoded in the genetic information (e.g. DNA). This process is heavily regulated, allowing cells to produce the appropriate gene products necessary for cell survival, adapting production as necessary for different cell environments. Gene expression is subject to regulation at several levels, including transcription, mRNA degradation, translation and protein degradation. When intact, this system maintains cell homeostasis, keeping the cell alive and adaptable to different environments. Malfunction in the system can result in disease states and cell death. In this dissertation, we explore several aspects of gene expression control by analyzing data from biological experiments. Most of the work following uses a common mathematical model framework based on Markov chain models to test hypotheses, predict system dynamics or elucidate network topology. Our work lies in the intersection between mathematics and biology ...

Download or read book Post Transcriptional Gene Regulation in Plants written by and published by . This book was released on 2006 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many elements contribute to the regulation of protein expression in eukaryotes. One such element, the upstream openreading frame (uORF), is the focus of this dissertation because it has not previously been well-characterized on a genome-wide scale. To undertake this project, an evaluation and improvement of full-length cDNA collections was implemented (Chapter 2). Most uORF amino acid sequences are not conserved in evolution, but those that are conserved seem likely to play sequence-specific roles in translational control of downstream, or major, open reading frames (mORF). By comparing full-length cDNA sequence libraries from Arabidopsis and rice we identified 26 homology groups of conserved peptide uORFs, only two of which had been reported previously. The conserved uORF amino acid sequences of each homology group were distinct from those of any other homology group, and within each uORF homology group mORFs always code for similar proteins in Arabidopsis and rice. Essentially all uORFs and their associated mORFs have been subject to purifying selection as determined by Ka/Ks analysis. The mORFs of conserved uORF transcripts encode transcription factors at a much higher frequency than expected (31% vs. 6% for the genome as a whole, p=10-7); a variety of different types of transcription factors are represented among these mORFs. Duplicate copies of conserved uORF-possessing genes that were created by whole genome duplication in an Arabidopsis ancestor are much more likely to have been retained in extant Arabidopsis than duplicates of the average gene (39% vs. 14%, p=5x10-3). Two of the 26 uORF homology groups were also found to be present in animals, indicating a high degree of sequence conservation and an ancient origin for these groups. The evolutionary history of one of these groups suggests that some uORFs arise by a 'transcriptional fusion' model.

Download or read book Plant RNA Biology written by Dóra Szakonyi and published by Frontiers Media SA. This book was released on 2019-11-18 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discoveries from the past decades revealed that RNA molecules are much more than inert intermediates between the coding DNA sequences and their functional products, proteins. Today, RNAs are recognized as active regulatory molecules influencing gene expression, chromatin organization and genome stability, thus impacting all aspects of plant life including development, growth, reproduction and stress tolerance. Innovations in methodologies, the expanding application of next-generation sequencing technologies, and the creation of public datasets and databases have exposed a new universe of RNA-based mechanisms and led to the discovery of new families of non-coding RNAs, uncovered the large extent of alternative splicing events, and highlighted the potential roles of RNA modifications and RNA secondary structures. Furthermore, considerable advances have been made in identifying RNA-binding and processing factors involved in the synthesis and maturation of different forms of RNA molecules as well as in RNA processing, biochemical modifications or degradation. This Research Topic showcases the broad biological significance of RNAs in plant systems and contains eight original research articles, one review and four mini-reviews, covering various RNA-based mechanisms in higher plants. Emerging new technologies and novel multidisciplinary approaches are empowering the scientific community and will expectedly bring novel insights into our understanding of the mechanisms through which RNA is regulated and regulates biological processes in plant cells.

Download or read book MicroRNAs in Plant Development and Stress Responses written by Ramanjulu Sunkar and published by Springer Science & Business Media. This book was released on 2012-02-21 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precise regulation of gene expression in both time and space is vital to plant growth, development and adaptation to biotic and abiotic stress conditions. This is achieved by multiple mechanisms, with perhaps the most important control being exerted at the level of transcription. However, with the recent discovery of microRNAs another ubiquitous mode of gene regulation that occurs at the post-transcriptional level has been identified. MicroRNAs can silence gene expression by targeting complementary or partially complementary mRNAs for degradation or translational inhibition. Recent studies have revealed that microRNAs play fundamental roles in plant growth and development, as well as in adaptation to biotic and abiotic stresses. This book highlights the roles of individual miRNAs that control and regulate diverse aspects of plant processes.
