This book was released on 2012-11-02 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die Mikronährstoffe Fe und Zn werden von Samen für die Entwicklung des Keimlings benötigt. Getreidekörner besitzen geringe Fe und Zn Gehalte und sind deshalb eine schlechte Quelle dieser Mikronährstoffe für die menschliche Ernährung.Um eine Anreicherung von Mikronährstoffen in Getreidekörnern zu erreichen, müssen jene aufgenommen, von der Wurzel zu Blättern oder Stängeln transloziert und von seneszenten Blättern oder Stängeln in die sich entwickelnden Körner retransloziert werden. Es ist bekannt, dass Stickstoffernährung eine wichtige Rolle bei der Retranslokation von Mikronährstoffen spielt, da die Anregung der Synthese von N-haltigen Fe Chelatoren wie Nikotianamin und Phytosiderophoren zu einer erleichterten Langstreckentranslokation dieser Metalle führen kann. Andererseits könnte eine N Düngung auch entgegengerichtet wirken, da dadurch Seneszenz verzögert wird und Mikronährstoffe in vegetativen Organen festgehalten werden. Bisher wurden die meisten Studien zu Mirkronährstoffretranslokation während der Blattseneszenz in hydroponischer Kultur oder in Topfexperimenten durchgeführt. Die hier vorliegende Arbeit untersuchte deshalb den Effekt unterschiedlicher N Düngungsformen auf Blattseneszenz und Mikronährstoffanreicherung in Weizenkörnern (Triticum aestivum cv. Akteur) unter Feldbedingungen in zwei aufeinanderfolgenden Jahren. Es wurde beobachtet, dass die Seneszenz des Fahnenblattes durch N Düngung verzögert war und zwar besonders dann, wenn N in Form von Nitrat oder Ammonium angeboten wurde, wohingegen Harnstoff weniger effektvoll war. In beiden Feldexperimenten führte die Zugabe von Ammonium nach der Blüte zu einem erhöhten Fe und Zn Gehalt in den Körnern. Dies lässt darauf schließen, dass diese Behandlung eine vielversprechende Strategie zur verbesserten Anreicherung dieser Mikronährstoffen in Weizenkörnern darstellt. Die Stickstoffversorgung führte auch zu erhöhten Nikotianamingehalten in Blättern und Blattexudaten, wohingegen die Phytosiderophorkonzentrationen weit weniger von den N Behandlungen beeinflusst waren. In einem Versuch die Fe und Zn Mobilisierung zu verbessern wurde Zitrat auf seneszierende Blätter von Freilandweizen gesprüht und die Mikronährstoffanreicherung in den Körnern gemessen. In N-gedüngten Pflanzen erhöhte die Zitratapplikation die Zitratexudation von seneszierenden Blättern nicht und die Fe und Zn Anreicherung in Körnern blieb unverändert. In ungedüngten Pflanzen hingegen erhöhte die Zitratapplikation die Zitratgehalte in den Exudaten seneszenter Blätter und führte zu signifikant erhöhten Fe Gehalten in den Körnern. In diesem Fall ist der positive Effekt der Zitratapplikation höchstwahrscheinlich auf eine verbesserte Fe Solubilisierung durch Zitrat in den Fahnenblättern zurück zu führen, da diese Behandlung keinen Effekt auf die Nikotianamin- und Phytosiderophorgehalte hatte. Die Ergebnisse dieser Arbeit zeigen, dass N Düngung die Fe und Zn Anreicherung von Weizenkörnern verbessern kann und zwar besonders dann, wenn die unterschiedlichen Effekte der N Düngerform berücksichtigt werden, während die Zitratapplikation zu keiner erhöhten Fe und Zn Anreicherung in den Körnern geführt hat.

Download or read book Biochemistry of Metal Micronutrients in the Rhizosphere written by John Manthey and published by CRC Press. This book was released on 1994-03-22 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochemistry of Metal Micronutrients in the Rhizosphere focuses on chemical factors and biological activities that control the uptake and translocation of essential metal micronutrients by plants and microorganisms. Emphasis is placed on current proposals describing the roles of microorganisms in controlling the biological activities of metal micronutrients in the rhizosphere. Coverage includes basic principles of siderophore-mediated Fe acquisition by microorganisms, siderophores as important regulators of Fe availability to plants and rhizosphere microorganisms, and microbial control of metal micronutrient supply to plants. The book evaluates plant uptake processes of Fe, Mn, and Zn in solution cultures and integrates this information with a rapidly developing understanding of rhizosphere events. Important consideration is given to the roles of metal ion chelation and soil chemistry in these biological activities. The current understanding of the biochemical events associated with Fe-deficiency in plants is discussed, including how these activities mediate micronutrient availability to both plants and soil microorganisms. This unique mixture of detailed coverage of the events that control biological activities of Fe, Mn, and Zn in the rhizosphere makes this book an essential reference.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, significant advancements have been made in the management of nutritional deficiency using genome engineering—enriching the nutritional properties of agricultural and horticultural crop plants such as wheat, rice, potatoes, grapes, and bananas. To meet the demands of the rapidly growing world population, researchers are developing a range of new genome engineering tools and strategies, from increasing the nutraceuticals in cereals and fruits, to decreasing the anti-nutrients in crop plants to improve the bioavailability of minerals and vitamins. Genome Engineering for Crop Improvement provides an up-to-date view of the use of genome editing for crop bio-fortification, improved bioavailability of minerals and nutrients, and enhanced hypo-allergenicity and hypo-immunogenicity. This volume examines a diversity of important topics including mineral and nutrient localization, metabolic engineering of carotenoids and flavonoids, genome engineering of zero calorie potatoes and allergen-free grains, engineering for stress resistance in crop plants, and more. Helping readers deepen their knowledge of the application of genome engineering in crop improvement, this book: Presents genetic engineering methods for developing edible oil crops, mineral translocation in grains, increased flavonoids in tomatoes, and cereals with enriched iron bioavailability Describes current genome engineering methods and the distribution of nutritional and mineral composition in important crop plants Offers perspectives on emerging technologies and the future of genome engineering in agriculture Genome Engineering for Crop Improvement is an essential resource for academics, scientists, researchers, agriculturalists, and students of plant molecular biology, system biology, plant biotechnology, and functional genomics.

This book was released on 2012-05-20 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1939 a new grade in the Iron Cross series was introduced, the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes). It was awarded for a variety of reasons, from skilled leadership to a single act of extreme gallantry, and was bestowed across all ranks, grades, and branches of service. As the war progresed, further distinctions were created for bestowal on existing winners, namely Oak-Leaves (Eichenlaub); Oak-Leaves with Swords (Eichenlaub und Schwertern); and Oak-Leaves with Swords and Diamonds (Eichenlaub, Schwerter und Brillanten). This book, the first in a sequence of four, covers winners of the Knights Cross and the Oak-Leaves distinction in the period 1939-40.
Download or read book Plastid Development in Leaves during Growth and Senescence written by Basanti Biswal and published by Springer Science & Business Media. This book was released on 2013-07-08 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chloroplast development is a key feature of leaf developmental program. Recent advances in plant biology reveal that chloroplasts also determine the development, the structure and the physiology of the entire plant. The books, published thus far, have emphasized the biogenesis of the organelle, but not the events associated with the transformation of the mature chloroplast to the gerontoplast during senescence. This book, with 28 chapters, is unique because it describes how the chloroplast matures and how it is subsequently transformed to become the gerontoplast during senescence, a process required for nutrient recycling in plants. This book includes a state-of-the-art survey of the current knowledge on the regulation and the mechanisms of chloroplast development. Some of the chapters critically discuss the signaling process, the expression potential of plastid DNA, the interaction of cellular organelles, and the molecular mechanisms associated with the assembly and the disassembly of organellar complexes and finally the modulation of chloroplast development by environmental signals.
