This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ARNr 5S est une partie intégrante du ribosome indispensable pour la synthèse des protéines. Cette fonction essentielle nécessite une régulation fine de l'expression des ARNr 5S en fonction des exigences cellulaires. L'ARNr 5S est codé par des gènes organisés en répétitions en tandem principalement situés dans les régions péricentromériques des chromosomes 3, 4 et 5 dans le génome Col-0 d'Arabidopsis thaliana. L'étude approfondie de l'organisation, la dynamique et la régulation épigénétique des gènes d'ARNr 5S reste cependant difficile du fait de l'absence d'assemblage de ces régions hautement répétées dans la séquence du génome d'Arabidopsis disponible dans TAIR10.Dans cette thèse, nous apportons de nouvelles informations sur les gènes d'ARNr 5S chez Arabidopsis. Nous avons confirmé les signatures d'ADN spécifiques par séquençage haut débit, identifié des polymorphismes spécifiques des régions chromosomiques portant des ADNr 5S et ainsi défini de nouvelles séquences de référence. Nous avons également étudié le statut épigénétique des gènes ARNr 5S, montrant que ces gènes sont globalement enrichis en marques répressives. Les loci situés sur les chromosomes 4 et 5 présentent également des modifications post-traductionnelles d'histones et des variants d'histone particuliers et caractéristiques d'une activité de transcription. Nous avons aussi montré que les loci d'ADNr 5S sont très dynamiques au sein de l'espèce Arabidopsis avec des variations entre différent écotypes du nombre de copies de gènes d'ARNr 5S et de l'importance relative de chaque cluster. En utilisant l'écotype Ler et des mutants spécifiques, nous montrons que le locus du chromosome 5 est une source majeure de réarrangements chromosomiques qui affectent l'organisation de la chromatine dans le noyau. Enfin, nous suggérons que des variations de l'état chromatinien des gènes d'ARNr 5S peuvent conduire à une différence de transcription dans les différents écotypes.Cette étude permet d'établir un rôle de l'organisation de la chromatine dans la régulation transcriptionnelle et l'organisation des gènes d'ARNr 5S.

Book Synopsis Epigenetic Memory and Control in Plants by : Gideon Grafi
Download or read book Epigenetic Memory and Control in Plants written by Gideon Grafi and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetics commonly acts at the chromatin level modulating its structure and consequently its function in gene expression and as such plays a critical role in plant response to internal and external cues. This book highlights recent advances in our understanding of epigenetic mechanisms as a major determinant through which internal and external signals, such as those occurring during hybridization, flowering time, reproduction and response to stress, communicate with plant cells to bring about activation of multiple nuclear processes and consequently plant growth and development. The outcome of these processes may persist for generations long after the initial cues have expired and may contribute to plant evolution.

Book Synopsis Epigenetics in Plants of Agronomic Importance: Fundamentals and Applications by : Raúl Alvarez-Venegas
Download or read book Epigenetics in Plants of Agronomic Importance: Fundamentals and Applications written by Raúl Alvarez-Venegas and published by Springer. This book was released on 2014-07-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, chromatin remodelling has emerged as an important regulator of gene expression and plant defense. This book provides a detailed understanding of the epigenetic mechanisms involved in plants of agronomic importance. The information presented here is significant because it is expected to provide the knowledge needed to develop in the future treatments to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases and to increase crop productivity. New approaches of this kind and the development of new technologies will certainly increase our knowledge of currently known post-translational modifications and facilitate the understanding of their roles in, for example, host-pathogen interactions and crop productivity. Furthermore, we provide important insight on how the plant epigenome changes in response to developmental or environmental stimuli, how chromatin modifications are established and maintained, to which degree they are used throughout the genome, and how chromatin modifications influence each another.

Download or read book The Centromere written by K. H. Andy Choo and published by Oxford University Press, USA. This book was released on 1997 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The centromere is an essential structure on all eukaryotic chromosomes that allows the equipartition of chromosomes during mitotic and meiotic cell divisions. Since its cytogenetic recognition as a constructed part of a chromosome many decades ago, great advances have been made in ourunderstanding of this intriguing structure, especially at the molecular level. This book brings together all available information on the centromere. It covers in details the DNA and protein components of this structure, and their individual functions, in species as diverse as budding and fissionyeasts, nematodes, Drosophila, mice, and humans; newly discovered roles of the centromere in marshalling "passenger" proteins; important emerging concepts such as latent centromeres and epigenetic factors; cytogenetic problems associated with centromere abnormalities; and practical application ofcentromere studies, such as in the construction of human artificial chromosomes for gene therapy. Supported by ample illustrations, the book is written with sufficient simplicity and detail to suit both specialist and non-specialist scholars. It is the first book on the subject

Download or read book The Barley Genome written by Nils Stein and published by Springer. This book was released on 2018-08-18 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley’s importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.

Book Synopsis Molecular Evolutionary Genetics by : Ross J. MacIntyre
Download or read book Molecular Evolutionary Genetics written by Ross J. MacIntyre and published by Springer. This book was released on 1985-12-31 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume in the Monographs in Evolutionary Biology series addresses issues that are part of an emerging area of research loosely called "mo lecular evolution. " Its practitioners include both molecular biologists cu rious about the evolutionary implications of their data and evolutionary biologists pushing their analyses to the molecular level. The union of these fields of molecular and organismal biology has been turbulent at times, and, as shall be seen, this dialectic has led to some very serious challenges to long-held notions about the role of natural selection in evolution and the economy of genome organization in eukaryotes. As an inevitable outgrowth of molecular biology, molecular evolution is necessarily a young discipline, but it can already point proudly to two major discoveries. The first, is the molecular clock, a concept that has emerged from the analysis of at least four data sets-amino acid sequences, immunologic data, DNA renaturation studies, and, recently, analyses of DNA sequences. The reality of a strong stochastic component in the evolution of nucleotide sequences can no longer be doubted, although the accuracy of the clock with regard to particular sequences and within particular groups of or ganisms should be independently measured each time it is used. Never theless, molecular clocks will assume increasingly important roles in phy logenetic reconstructions, especially since the fossil record is so fragmentary. The second major discovery of molecular evolution has been the incredible complexity of the eukaryotic genome.
