Subcellular localization of Glutathione peroxidase-like enzymes (GPXLs) in Arabidopsis thaliana and characterization of GPXL3 deficient mutants
(2017-03-27)A common feature of plants being exposed to diverse forms of environmental stress is the increased formation of reactive oxygen species (ROS) in both photosynthesis and respiration. Formation of ROS, however, is not ... -
Influence of nitrogen and water supply on evapotranspiration, yield and agronomic water use efficiency of winter wheat
(2017-05-09)The predicted climate change for North West Europe, which will be characterized by higher temperatures and lower rainfall during the summer months, will challenge future food production. Against this background, the question ... -
A global barley diversity panel uncovered novel drought inducible QTL and footprints of evolution
(2017-03-13)The fibrous root system is a visible sign of ecological adaptation among barley natural populations. In the present study, we utilized rich barley diversity to dissect the genetic basis of root system variation and its ... -
The impact of large-scale land-acquisition in East Africa on poverty reduction and the rural economy: Studies in Ethiopia and Uganda
(2017-02-28)There is an increasing interest of acquiring farmland abroad, especially following the food price crisis in 2007/08. East Africa is a hotspot of activities, and given the high prevalence of poor people in the area, impacts ... -
Mechanistic details into NADPH oxidase mediated resistance against Heterodera schachtii in Arabidopsis thaliana
(2017-03-24)The oxidative burst, production of Reactive Oxygen Species (ROS) in response to pathogen attack, is an important component of plant defence mechanisms. It is now generally recognised that the major source of ROS during an ... -
Spatial variation of biomass energy supply and demand in rural Nepal
(2017-02-24)In Nepal, the share of biomass in total energy consumption is about 88 % and of biomass for cooking and heating about 90 % in 76 % of the households. Fuelwood, crop residues and dung are the three main biomass types. The ... -
Analysis of wheat (Triticum aestivum L.) resistance to cereal cyst nematode Heterodera filipjevi by genome-wide association mapping
(2017-02-14)The cereal cyst nematode <em>Heterodera filipjevi</em> is an important plant parasite causing substantial yield loss in wheat. The use of resistant cultivars is the preferable method to manage this nematode, however, only ... -
Nachhaltigkeit in kleinen und mittelständischen Unternehmen der nordrhein-westfälischen Lebensmittelindustrie: Eine empirische Analyse
(2017-03-02)In der heutigen Gesellschaft spielt das Thema Nachhaltigkeit eine bedeutende Rolle. Gerade Lebensmittel, die von Konsumenten tagtäglich konsumiert werden, unterliegen einer besonderen Beobachtung. Die zunehmende Konzentrierung ... -
Effects of heat and drought stress on cereal crops across spatial scales
(2017-02-10)The production of cereal crops is increasingly influenced by heat and drought stress. Despite the typical small-scale sub-regional variability of these stresses, impacts on yields are also of concern at larger regional to ... -
Global mRNA and miRNA transcriptome profiling of peripheral blood mononuclear cells to investigate the host immunogenetic response to PRRSV vaccination in pigs
(2017-01-20)This dissertation aims to identify the candidate genes of the functional network of host immune response to porcine reproductive and respiratory syndrome virus (PRRSV) vaccine in pigs; to explore the breed differences on ... -
Prototypenentwicklung eines solaren Trockners für holzartige Biomasse
(2017-01-24)Eine energieeffiziente Verbrennung von Holz ist grundsätzlich nur möglich, wenn die Biomasse einen adäquat niedrigen Wassergehalt aufweist. Zur Aufbereitung der standorteigenen Biomasse aus Obstbaumplantagen wurde an der ... -
Genetic variation of traits related to salt stress response in Wheat (Triticum aestivum L.)
(2017-01-24)Salinity is one of the most severe abiotic stresses perceived by plants, and is continuously increasing due to climatic change and poor irrigation management practices. It is currently affecting ~800 million hectares of ... -
Urban green spaces enhance carbon sequestration and conserve biodiversity in cities of the Global South: case of Kumasi, Ghana
(2017-01-24)Urbanization has the propensity to alter ecosystems, enervate ecosystem function and possibly jeopardise human wellbeing. While adequate integration of nature into the city landscape can pragmatically ameliorate urban ... -
Effects of different feeding regimes applied during rearing of dairy calves: circulating adiponectin and insulin sensitivity in early life and around the first lactation
(2016-12-20)Metabolic programming is defined as an early stimulus with long term effect. In dairy cows, feeding in the preweaning period has long term effects on later milk production. However, the influence on metabolic and endocrine ... -
Imperfect competition in an oligopsonistic setting: A study on the German raw milk market
(2016-11-22)Agricultural markets are best characterized as oligopsonistic markets; usually many farmers face only few manufacturers. The raw milk market in Germany exhibits a high concentration of dairy processors opposed to a large ... -
Social interactions, aspirations, and agricultural innovations: Linkages with income and food security in rural Ethiopia
(2016-11-09)The persistence of poverty in some parts of the society across the globe inspired recent studies in development economics to embrace the use of multidisciplinary tools and concepts to better understand the situation of the ... -
Ausgewählte Einflussfaktoren auf den Nützlingseinsatz gegen Thrips und Blattläuse im ökologischen Topfkräuteranbau unter Glas
(2016-11-07)Bislang liegen nicht ausreichend wissenschaftliche Daten vor, um effiziente Nützlingsmanagementsysteme im Topfkräuteranbau zu realisieren. Der Fokus dieser Arbeit lag daher darin, den Einfluss der biotischen und abiotischen ... -
Statistical relational learning of semantic models and grammar rules for 3D building reconstruction from 3D point clouds
(2016-11-04)Formal grammars are well suited for the estimation of models with an a-priori unknown number of parameters such as buildings and have proven their worth for 3D modeling and reconstruction of cities. However, the generation ... -
Functional studies of microRNA 17-92 cluster members in bovine granulosa cells and oocyte maturation
(2016-10-13)Dynamic transcript of genes expression are believed to occur during follicular development and oocyte maturation, which one way or the other is regulated by a post-transcriptional modifier, namely microRNA. In the previous ... -
