Available in PDF, EPUB and Kindle. Book excerpt: Pour la première fois en langue française, cet ouvrage rassemble les principales connaissances acquises ces vingt dernières années sur l'assimilation de l'azote nitrique, ammoniacal et moléculaire et sur la synthèse des acides aminés et des protéines chez les plantes d'intérêt agronomique. Il traite également des mécanismes de gestion et de mise en réserve de l'azote organique au cours de la croissance et du développement des végétaux. Il signale enfin les conséquences d'un apport excessif d'azote sur le rendement et la qualité des récoltes ainsi que sur la préservation de l'environnement. La maîtrise de la nutrition azotée permettra d'envisager de nouvelles stratégies d'amélioration des espèces et de nouveaux itinéraires techniques de culture. Public : enseignants et étudiants du supérieur, chercheurs, agronomes.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'activité de croissance des plantes se trouve souvent limitée par les conditions contraignantes de l'environnement. La salinité du sol est l'une des majeures contraintes abiotiques qui ne cesse d'envahir les surfaces cultivés chaque année. Elle entraine chez les espèces glycophytes des perturbations d'ordre osmotique, nutritionnel et métaboliques. La nutrition et le métabolisme de l'azote minéral constituent des étapes primordiales dans la synthèse des acides aminés et des composés azotés indispensables chez les plantes. Par conséquent, l'étude de l'expression des enzymes impliquées dans l'assimilation d'azote telle que l'asparagine synthétase (AS, EC 6.3.5.4) chez l'arabette des dames (Arabidopsis thaliana) permet d'avancer nos connaissances sur la régulation transcriptionnelle du métabolisme azoté sous stress salin. Au cours des travaux de recherche entamés dans le cadre de cette thèse, un intérêt particulier est accordé au gène ASN2 chez Arabidopsis. Les résultats obtenus ont montré que la mutation ASN2 a accentué les effets du NaCl sur l'assimilation de l'ammonium. Le mutant asn2-1 se montre plus sensible au stress salin que le sauvage malgré que l'absence des transcrits du gène ASN2 est associé à une expression importante du gène ASN1. L'inhibition de l'activité glutamine synthétase (GS, EC 6.3.1.2), la faible activité aminatrice de la GDH (NADH-GDH, EC 1.4.1.2) sous stress salin ainsi que l'absence des transcrits ASN2 seraient à l'origine de l'accumulation de l'ammonium chez le mutant asn2-1. Toutefois, l'application exogène de l'ammonium nous a montré que l'action du NaCl sur l'expression de l'asparagine synthétase n'est pas directement liée à l'accumulation endogène d'ammonium. L'accumulation d'autres métabolites tels que l'asparagine, la glutamine et la glutamate pourrait être à l'origine des effets du sel sur l'expression des gènes ASN.

Book Synopsis The Origin of Life on the Earth by : A. I. Oparin
Download or read book The Origin of Life on the Earth written by A. I. Oparin and published by Elsevier. This book was released on 2013-09-03 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Origin of Life on the Earth covers the proceedings of the First International Symposium of The Origin of Life on the Earth, held at Moscow on August 19-24, 1957. This symposium brings together numerous scientific studies on the evolutionary principles and the different stages in the evolutionary development of matter. This book is organized into seven parts encompassing 60 chapters. The first parts discuss evidence that on the formation of hydrocarbons and their derivatives on the surface of the Earth even before the emergence of life. The subsequent parts are devoted to the many asymmetrical syntheses under the influence of circularly-polarized ultraviolet light, by catalytic reactions occurring on the surface of quartz crystals, and spontaneously by slow crystallization from solutions. These topics are followed by reviews on the possible means of abiogenic formation of amino acids, porphyrins, protein-like polymers, polynucleotides and other high-molecular organic compounds. Considerable chapters explore the complete possibility of the primary formation of these compounds on the surface of the Earth even before life was present on it. Other general topics covered include nucleic acids, nucleoproteins and viruses. The last part considers general biochemical problems connected with the further development of metabolism. This book will be of value to astronomers, physicists, geologists, chemists, and biologists.
