Developing a plant-based fertilizer for organic vegetable production (Project)
...Basic raw material for the novel fertilizer will be shoot biomass from different legumes like red clover and lucerne with a low carbon-to-nitrogen (C:N) ratio. Field experiments will be performed with ten different legume species to select three legumes. ...In the field experiments with legumes the legumes will be harvested up to 7 to 9 times a year to achieve a low C : N ratio in harvested shoot biomass. ...

Genomcs-driven analysis of the wheat/Fusarium pathosystem for healthy food and feed product development (Project)
...The aim of the project is the application of genome based and proteomic methods for (1) the selection for resistance against Fusarium (FHB) and for reduced mycotoxin production, (2) the analyses of the host-pathogen-interaction wheat/fusarium, (3) population and association genetics studies on Fusarium graminearum isolates. ...Studies conducted at the JKI aim at the construction of a high resolution mapping population for a FHB-QTL located on chromosome 2A of Triticum monococcum followed by marker saturation and the identification of candidate genes. ...In 2016 the high-resolution mapping population could be increased to 1991 F2-plants, providing a genetic resolution of 0.025 % recombination. 421 heterozygot recombinant plants and 16 homozygous recombinant plants could be identified for the first QTL-Intervall and 242 heterozygous recombinant plants and 7 homozygous recombinant plants could be selected for the second QTL-Interval. ...

Characterisation and comparison of Salmonella enterica subsp. diarizonae strains isolated from animal (mainly sheep), food and human sources. (Project)
...One example is Salmonella enterica subsp. diarizonae serovar IIIb 61:k:1,5,(7) , which is known to be highly adapted to sheep, but can be also found in other mammals, birds, reptiles and humans. Extensive studies have shown, that Salmonella 61:k:1,5,(7) could be detected in sheep herds from Sweden, Norway, UK, Spain, Italy, Switzerland and the USA. ...Another aim of the project is to investigate mechanisms of host adaption in Salmonella 61:k:1,5,(7) based on genome data. Therefore, distribution of virulence genes and virulence plasmids is of major interest. ...

FOR 536 P5: Quantification and biogeochemical modeling of C and N turnover processes and biosphere-atmosphere exchange of C and N compounds (Project)
...Furthermore, manual measurements of N2O, CH4 and CO2 in nitrogen fertilization and irrigation experiments will be conducted to simulate the effects of a) management regime change (i.e. low dose nitrogen fertilization of grasslands), and b) inter-annual variation in precipitation. ...To obtain a regional set of CO2/H2O fluxes for model testing ultralight flights with onboard EC measurements of CO2/H2O fluxes will be performed. ...It also requires the integration of MOBILE in the MAGIM modelling framework, since other models within MAGIM, i.e. SWAT and CMF (regional hydrology models, P7), sward production model FOPROQ and sheep model (P3/ P4) and SAMT (GIS-coupled wind erosion model, P9), are delivering important driving and initialization parameters (e.g. ...

Selection und characterisation of barley with resistance to free-living nematodes (Project)
...The new genetic linkage map comprised 857 molecular markers that cover 1,157 cM on seven linkage groups. Using phenotypic data, five QTLs associated with resistance to P. neglectus were mapped by composite interval mapping on four (3H, 5H, 6H and 7H) linkage groups. Four QTLs associated with resistance to P. penetrans designated as Ppe2H, Ppe5H-1, Ppe6H-1 and Ppe7H were mapped on linkage groups 2H, 5H, 6H and 7H, respectively. Comparative QTL analysis revealed a co-localization of resistance-associated QTLs of P. neglectus (chromosomes 5H Pne5H and 6H Pne6H) and P. penetrans Ppe5H-1 and Ppe6H-1....

Collaborative project: Mapping of resistance genes against Aphanomyces euteiches, an important pathogen of the pea root rot complex by using a microarray. Subproject 1 (Project)
...By crossing a resistance donor with an elite line a population of 316 F2-plants was developed and a high resolution genetic map was generated by using the GenoPea-microarray. QTL analysis identified 9 resistance loci with LOD-scores above or slighly below the genome-wide statistical significance threshold of 3.8. ...A validation of this marker combination for a total of 278 plants of an independent F2:3 population was done in two runs. For the second run a correlation between the resistance degree predicted by markers and the identified resistance by phenotyping could be confirmed. ...

Alternative pest control methods with insect pathogenic nematodes to keep corn rootworm populations under the injury threshold (Project)
...Overall objectivesComparing nematode-based biological control options as alternatives to synthetic pesticides in the management of established Diabrotica maize pest populationsSpecific objectives1. Investigating the efficacy alternative control measures, i.e. nematode-based biological control products applied into soil during sowing, in their efficacy at keeping larvae of established D. v. virgifera populations below threshold levels2. ...The latter is suggested to be 0.75 for irrigated conventional maize growing in northern Italy (R. Edwards, 2011, pers. comm.).o Ca. 12 plants of each 24 plots to be infested, i.e. 300 and/or 500 eggs x 12 x 24 = 86,400 eggs x 2 fields = 172,800 eggs (egg production in CABI labs on-going, if 500 egg infestation for root damage x 6 plants x 24 x 2 fields = 144,000 extra eggs).o 1 D. v. virgifera emergence cage covering 6 plants will be placed over each plot (1 cage x 4 plots x 6 treatments = 24 cages x 2 fields = 48 cages on 288 plants)o Root damage and yield will be assessed from 6 infested plants per each of the plots of each treatment (6 plants x 4 plots x 6 treatments = 168 plants x 2 = 288 plants)...

Actions of Botulinum Toxin A in nerve-muscle-tissue-cultures: A proof-of-principle-study (Project)
...Muscle activity was significantly different between the sham and botulinum toxin treated group (Kruskal-Vallis test, p-values for 24, 48 and 72 hours: 1.8x10-5, 1.9x10-2 und 6.0x10-4, respectively). In more than half of the cultures exposed to botulinum toxin, muscle activity declined to less than 0.15 Hz. Under control conditions the corresponding value was 1.58 Hz. ...The limits of detection of the test system were between 1 and 2 mouse-LD50-units. The results suggest that testing of 30 cell cultures should be statistically sufficient to show whether or not a test solution contains botulinum toxin A at a concentration corresponding to 2 mouse-LD50-units or higher. ...
