Collaborative project: Development of automated techniques for early field diagnosis of downy mildew, Plasmopara viticola, for adapted plant protection in organic viticulture (Project)
...AuDiSens is subdivided into six working packages, as are AP1) studies on the epidemiology of P. viticola including PIWI- and traditional cultivars (JKI-OWS); AP2) evaluation of sensors (JKI-ZR), AP3) data processing and analysis of sensor based raw data (LemnaTec); AP4) data mining (TU DO); AP5) Pilot-study of field diagnosis (all partners); AP6) Transfer of knowledge into viticulture and research communities. ...Validation of the results of sensor data analysis (AP 3/AP4) and process optimization. AP5 consists a pilot study with the aim to investigate the precision of disease diagnostic in the field. ...For JKI-OWS main focus is on AP1, which is subdivided into AP1.1) studies on the epidemiology of P. viticola on the host plant under controlled and natural conditions, and AP1.2) infection events in the field under different copper regimes. ...

SPP 1315: Microbial metabolism of model pesticides in the drilosphere and effect on N2 O production: Linking processes with populations (Project)
...Hypotheses: 1. The drilosphere (i.e., burrow linings, gut content, and casts) harbours hitherto unknown, highly active prokaryotes that transform phenoxyacetic acid herbicides and their degradation products. 2. Phenoxyacetic acid herbicides and their degradation products inhibit N2 O production and growth of hitherto unknown nitrifiers and denitrifiers in the drilosphere. Aims: To assess the microbiology of the drilosphere 1.Fate of pesticides and degradation products (MCPA and 2,4-DCP) 2.Effect of pesticides on N2 O production by denitrifiers and nitrifiers 3.Identify and isolate key prokaryotes associated with pesticide degradation and N2 O production...

Mechanism of toxicity of triazole fungicides (Project)
...A reduction of the expression of the Vitamin D receptor (VDR) - which is regulated homologously with calcitriol levels (if calcitriol, then VDR) - in all organs examined (Testes, adrenals, prostate), accompanied by an induction of CYP27B1 in the liver (activates Vitamin D3) further suggests an involvement of the Vitamin D3 homeostasis (rf. to 2012 report on projects 1322-456 and 499). ...Triazole fungicides show reprotoxic and carcionogenic properties, an influence on the endocrine system and may retard ossification in laboratoiry animals (e.g. EFSA (2010) and CA-Report Propiconazol acc. to 98/8/EC, RMS FI(2007)). ...Changes in gene expression levels of the transporters Abcb1a, Abcb1b und Slco1a2 and enzymes involved in xenobiotic as well as Vitamin D metabolism and function (Cyp3a, Ugt1a, Cyp2r1, Cyp27b1, Vdr) could be confirmed and were described in detail. ...

Cell culture models of human nasal mucosa for in-vitro drug absorption studies (follow-up project to 1328-469) (Project)
...These results implied functional expression of Pgp as well as MRP1, 3 and 5. Activity of MRP2 and 4, respectively, was indicated by significant higher amounts of erythromycin and ADV, respectively, accumulated in absence of particular inhibitor. ...Indirect immunofluorescence staining resulted in positive signals for Pgp and MRP1 – 5 as well as for PEPT2 and organic cation and anion transporters in all models. ...'Activity of Multidrug Resistance-Associated Proteins 1-5 (MRP1-5) in the RPMI 2650 Cell Line and Explants of Human Nasal Turbinate.' ...

Collaborative project: The Utilization of virus resistance derived by Hordeum bulbosum for a sustainable barley breeding by the help of 'GenOmics'. Subproject 1 (Project)
...The researched genes comprised Ryd4 and Ryd5, which deliver resistance and tolerance to Barley Yellow Dwarf Virus (BYDV), respectively, as well as Rym14 and Rym16, which confer resistance to Barley Yellow Mosaic Virus (BaYMV) and Barley Mild Mosaic Virus (BaMMV). ...Thereby, the intervals could be reduced to 67 kb (Ryd4), 1,4 Mbp (Ryd5), 2 Mbp (Rym14) and 1,2 Mbp (Rym16) of the barley reference genome. ...

Influence of folic acid on CXCR4-dependent migration of malignant colon carcinoma cells (Project)
...In another meta-analysis with 12 clinical intervention-studies, in which 0,5 to 5 mg folic acid per day were administered (one study used 40 mg folic acid/ day),the folic-acid group showed also a higher but not significant risk to develop cancer (Vollset et al., 2013). In preliminary studies we could show, that folic acid up-regulates the chemokinreceptor CXCR4 on mRNA-level in a dose-depenedent manner (Sonderforschungsantrag 1322-546). CXCR4 plays a crucial role for metastasis, tumor growth and tumor angiogenesis (Domanska et al. 2013; Orimo et al. 2005). ...

Production of butanol from bioethanol by heterogeneous catalysis (Project)
...Bioethanol is a potential platform chemical and can be catalytically converted to important chemicals, e.g. ethylene, 1-3-butadien, n-butanol. Our research focus on the production of n-butanol by the guerbet reaction. Ethanol, known as alcohol, is produced in the world largest and most important fermentation process from carbohydrates (sugar, starch). In the last 8 years the world Ethanol production increased from 24 to 85 million t/a because of its usage as fuel additive. ...This reaction requires high temperatures (200-450°C) and can take place in the liquid or gas phase. n-Butanol is one of the most important commodities worldwide. The majority of the 3 million t/a is produced via the oxo process from propylene and n-butanol is used mainly directly or indirectly as a solvent. ...
