Das Projekt "Barley dwarfs acting big in agronomy. Identification of genes and characterization of proteins involved in dwarfism, lodging resistance and crop yield" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Deutsche Forschungsgemeinschaft.Barley (Hordeum vulgare) is an important cereal grain which serves as major animal fodder crop as well as basis for malt beverages or staple food. Currently barley is ranked fourth in terms of quantity of cereal crops produced worldwide. In times of a constantly growing world population in conjunction with an unforeseeable climate change and groundwater depletion, the accumulation of knowledge concerning cereal growth and rate of yield gain is important. The Nordic Genetic Resource Center holds a major collection of barley mutants produced by irradiation or chemical treatment. One phenotypic group of barley varieties are dwarf mutants (erectoides, brachytic, semidwarf, uzu). They are characterized by a compact spike and high rate of yield while the straw is short and stiff, enhancing the lodging resistance of the plant. Obviously they are of applied interest, but they are also of scientific interest as virtually nothing is known about the genes behind the development of plant dwarfism. The aim of this project is to identify and isolate the genes carrying the mutations by using state of the art techniques for gene cloning at the Carlsberg Laboratory. The identified genes will be connected with the mutant phenotype to reveal the gene function in general. One or two genes will be overexpressed and the resulting recombinant proteins will be biochemically and structurally characterized. The insights how the mutation effects the protein will display the protein function in particular. Identified genes and their mutant alleles will be tested in the barley breeding program of the Carlsberg brewery.

Das Projekt "Modeling Geomagnetic Excursions" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum.Periods of extreme geomagnetic change such as geomagnetic excursions have frequently occurred throughout geological time. Characterizing their behaviour is essential for a full understanding of the geodynamo and the interaction of Earths magnetic field and the space environment. We propose to model the global behaviour of Earths magnetic field between 10 and 50 ka using palaeomagnetic data. During this time the geomagnetic field showed significant variability in direction and intensity, including two well documented excursions: Laschamp and Mono Lake. No model currently exists that spans the total length of this time period, yet this period could provide great insights into the geodynamo. The ultimate goal of the project is to synthesize the results from our empirical modelling with those from numerical dynamo simulations, so that a deeper physical understanding of geodynamo processes can be gained. We will compile all sedimentary and volcanic palaeomagnetic data coupled with geochronological data spanning this period. This data will be added to a community available database along with all rock magnetic and sedimentological metadata. This will allow a detailed assessment of the data used in the modelling. Low quality palaeomagnetic data and erroneous age models may distort geomagnetic field structures generated by our new model and it is a key objective of this study to assess the fidelity of the palaeomagnetic and chronological data included in the modeling. Using this data we will construct a temporally continuous global spherical harmonic geomagnetic field model through a regularized least squares inversion of the data using spherical harmonics in space and cubic B splines in time. This model will enable assessment of the geomagnetic at the core-mantle boundary, the Earths surface and at elevated altitudes. Our key scientific objective is to determine where excursions fit into the spectrum of geomagnetic field variations and how the geodynamo processes that generate excursions differ from those that produce secular variation and reversals.
Das Projekt "Einfluss von Ionen auf das atmosphärische Partikelwachstum - Studien an einem Flussreaktor und einer Aerosolkammer" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Universität Bayreuth, Forschungsstelle für Atmosphärische Chemie.Sekundäre Partikelneubildung ist eine Hauptquelle für atmosphärische Partikel mit wichtigen Folgen für das Klima und die menschliche Gesundheit. Dieses Vorhaben untersucht die Rolle von Luft Ionen bei der sekundären Partikelneubildung in Flussreaktor- und Aerosolkammer-Experimenten unter kontrollierten Laborbedingungen. Trotz beträchtlicher Fortschritte in der Messtechnik zur Untersuchung der atmosphärischen Nukleation und des Partikelwachstums bestehen weiterhin Verständnislücken hinsichtlich der grundlegenden physikalischen und chemischen Prozesse. Insbesondere die möglichen Effekte von Ionen-Partikel-Wechselwirkungen und von Ionenchemie auf die Partikelneubildung werden kontrovers diskutiert. In Ergänzung zu bestehenden Forschungsprogrammen hinsichtlich der Rolle von Ionen im initialen Nukleationsschritt wird vorgeschlagen, Ionen-Partikel-Wechselwirkungen während des anschließenden Partikelwachstums zu untersuchen und sich dabei auf direkte Messungen des Ladungszustands, der Wachstumsraten und der chemischen Zusammensetzung von sekundärem organischem Aerosol zu konzentrieren. Hierzu werden der Ladungszustand und die Wachstumsraten von Partikelpopulationen mit einem modifizierten Mobilitätspartikelspektrometer unter wohldefinierten Randbedingungen in Laborexperimenten quantifiziert. In einem nächsten Schritt werden die neuartigen Messmöglichkeiten unseres Aerosol-Massenspektrometers CAChUP voll ausgeschöpft, um den Beitrag verschiedener organischer Vorläufergase zur chemischen Zusammensetzung von sekundärem organischen Aerosol bei variierenden Ladungszuständen zu quantifizieren. Schließlich werden die Ergebnisse dieser Experimente durch Messungen zur sekundären organischen Partikelbildung bei wohldefinierten Ionenkonzentrationen an einer Aerosolkammer überprüft. Die vorgeschlagene Forschungsagenda ist somit darauf abgestimmt, mögliche ladungs-katalysierte chemische Mechanismen bei der sekundären Aerosolbildung besser einzuordnen.

Das Projekt "Palaeo-Evo-Devo of Malacostraca - a key to the evolutionary history of 'higher' crustaceans" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Universität Greifswald, Zoologisches Institut und Museum, Abteilung Cytologie und Evolutionsbiologie.In my project I aim at a better understanding of the evolution of malacostracan crustaceans, which includes very different groups such as mantis shrimps, krill and lobsters. Previous studies on Malacostraca, on extant as well as on fossil representatives, focussed on adult morphology.In contrast to such approaches, I will apply a Palaeo-Evo-Devo approach to shed new light on the evolution of Malacostraca. Palaeo-Evo-Devo uses data of different developmental stages of fossil malacostracan crustaceans, such as larval and juvenile stages. With this approach I aim at bridging morphological gaps between the different diverse lineages of modern malacostracans by providing new insights into the character evolution in these lineages.An extensive number of larval and juvenile malacostracans is present in the fossil record, but which have only scarcely been studied. The backbone of this project will be on malacostracans from the Solnhofen Lithographic Limestones (ca. 150 million years old), which are especially well preserved and exhibit minute details. During previous studies, I developed new documentation methods for tiny fossils from these deposits, e.g., fluorescence composite microscopy, and also discovered the first fossil mantis shrimp larvae. For malcostracan groups that do not occur in Solnhofen, I will investigate fossils from other lagerstätten, e.g., Mazon Creek and Bear Gulch (USA), or Montceaules- Mines and La-Voulte-sur-Rhône (France). The main groups in focus are mantis shrimps and certain other shrimps (e.g., mysids, caridoids), as well as the bottom-living ten-footed crustaceans (reptantians). Examples for studied structures are leg details, including the feeding apparatus, but also eyes. The results will contribute to the reconstruction of 3D computer models.The data collected in this project will be used for evaluating the relationships within Malacostraca, but mainly for providing plausible evolutionary scenarios, how the modern malacostracan diversity evolved. With the Palaeo-Evo-Devo approach, I am also able to detect shifts in developmental timing, called heterochrony, which is interpreted as one of the major driving forces of evolution. Finally, the reconstructed evolutionary patterns can be compared between the different lineages for convergencies. These comparisons might help to explain the convergent adaptation to similar ecological niches in different malacostracan groups, e.g., life in the deep sea, life on the sea bottom, evolution of metamorphosis or of predatory larvae.As the project requires the investigation of a large number of specimens in different groups, I will assign distinct sub-projects to three doctoral researchers. The results of this project will not only be published in peer-reviewed journals, but will also be presented to the non-scientific public, e.g., during fossil fairs or museum exhibitions with 3D models engraved in glass blocks.
Das Projekt "Forest functions arrangement with the CBD's Ecosystem Approach - A study on the Bengawan Solo River Basin, Java, Indonesia" wird/wurde gefördert durch: Deutscher Akademischer Austausch Dienst. Es wird/wurde ausgeführt durch: Universität Göttingen, Burckhardt-Institut, Professur für Naturschutz und Landschaftspflege.The natural capital of forests consists to a great extend of the forests environmental functions for human well-being, which not only include goods and services (source and sink functions) but also include life-support functions that reflect ecosystem performance (ecosystem functioning). Shifting the management approach from a traditional one to one that is more aware of the ecosystem complexity, the idea of 'ecosystem functioning is appearing to tackle gradual declines of ecosystem functions. Within CBDs framework, the Ecosystem Approach has been introduced on account of the necessity for open decision making with strong links between all stakeholders and the latest scientific knowledge due to uncertainty and unpredictability in nature. The Ecosystem Approach is still in need of further elaboration, even though as a concept Ecosystem Approach has been widely accepted. To aim forest enhancement, this approach has been regarded as the most feasible concept for the study area, the Bengawan Solo River Basin - Java, Indonesia. Therefore the principles and operational guidelines will be used to analyse and evaluate the current forest management in those areas of the Bengawan Solo River Basin, in which ecosystem function is the basis for forest development area. This research focuses on ecological functions of forests at various levels of ecosystem management planning, from the forestry sectors point of view.
