Uncovering the role of falcarin-type polyacetylenes in carrots for enhanced resistance
(2024-06-05)Falcarin-type polyacetylenes (PA) are a group of putative plant defense metabolites produced by carrot plants. However, the elucidation of PA biosynthetic pathway and the biological function of PA in carrot plants are not ... -
Interactions between endophytic Metarhizium brunneum and oilseed rape plants: effects on plant health and possible mechanisms
(2023-10-18)Fungi of the genus Metarhizium, belonging to the order Hypocreales, are well-known entomopathogens that primarily infect insects. However, recent research has revealed their multifunctional lifestyles, including their ... -
Characterization of Leptosphaeria maculans races in Germany and studies on resistance of Brassica napus to blackleg disease
(2023-03-23)Leptosphaeria maculans, a phytopathogen causes blackleg disease, is an economically significant biotic stress that affects oilseed rape (B. napus) production worldwide. Blackleg disease can be controlled by stubble management, ... -
Characterisation of genotypic and tissue specific resistance in oilseed rape (B. napus) against Sclerotinia sclerotiorum
(2020-01-03)Sclerotinia sclerotiorum is a necrotrophic ascomycete and the causal agent of stem rot disease, an economically important constraint in the cultivation of oilseed rape (Brassica napus L.). Since cultivar resistance is a ... -
Occurrence and Importance of Foliar Diseases on Maize (Zea mays L.) in Central Europe
(2018-07-09)In the last decade, the acreage of maize has increased continuously in Central Europe due to its high yield and diverse uses as food, feed and bio-energy. This has led to more intense maize cultivation in many regions with ... -
Unfavorable environmental conditions: Consequences for microbial metabolism and C stabilization in soil
(2017-11-21)Soil microorganisms are primary drivers of biogeochemical cycles, making them an important link between pedosphere and atmosphere. Soil microbes control the carbon (C) transfer from terrestrial ecosystem to the atmosphere ... -
Influence of agronomic practices on the development of soil suppression against cyst-forming plant-parasitic nematodes
(2017-05-05)Cyst-forming nematodes are a major group of plant pests of economic importance worldwide. There are well-documented cases of suppressive soils where plant-parasitic nematodes are maintained at very low population densities ... -
Effect of temperature on the interactions between beet cyst nematodes (Heterodera schachtii and Heterodera betae) and sugar beet
(2016-10-28)Climate change is expected to cause a mean annual temperature increase in Germany of 2 °C by 2050 and up to 4 °C by 2100. This is likely to have effects on crop development and pathogen development as well. For this Ph.D. ... -
Nitrogen Efficiency of Winter Oilseed Rape and its Prediction by Hyperspectral Canopy Reflectance and Electrical Capacitance
(2016-07-01)Oilseed rape is the third most important oil crop worldwide. Under many conditions it is characterised by relatively low nitrogen efficiency. In Germany a nitrogen supply of 240 kg N ha 1 is aimed at which derives from ... -
Effect of climate change on population dynamics and damage potential of insect pests on oilseed rape
(2015-05-21)Biotic stress such as pests can cause high yield losses in agricultural crop systems. It has been estimated that global warming will increase these rates. Thus, the impact of global warming on the distribution and abundance ... -
Weeds in a changing environment
(2015-04-10)In the course of the past decades, various impacts of climate change have been recognized to pose a challenge to arable production systems. Among others, shifts in the species composition of weed communities, particularly ... -
Host-parasite interaction between the potato tuber rot nematode (Ditylenchus destructor), stem nematode (Ditylenchus dipsaci) and potato
(2015-03-18)Nematodes are among important pest constraints influencing potato production worldwide. The tuber rot nematode, Ditylenchus destructor Thorne 1945, and the stem nematode, Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936, ... -
Studies about Fusarium infection of emmer and naked barley during grain ripening and the post-harvest period
(2014-12-01)The influence of Fusarium graminearum infection on mycotoxin formation and on the protein composition of emmer and naked barley grains was investigated during grain ripening from milk ripe grains until ripeness and during ... -
High Fumonisin Content in Maize: Search for Source of Infection and Biological Function
(2014-05-22)Fusarium is a large and complex genus, comprises important pathogens most of which are able to produce mycotoxins. Maize is a host of several Fusarium species that cause ear rot, kernel rot, stalk rot and also seedling ... -
Chemical interactions between Verticillium longisporum and oilseed rape Brassica napus
(2014-05-20)Verticillium longisporum is a devastating vascular pathogen which infects plants from Brassicacae including oilseed rape Brassica napus, the pathogen infects the plant through the root and enters the vascular system to ... -
Factors regulating the population dynamics and damage potential of pollen beetle (Meligethes aeneus F.) on crops of oilseed rape
(2014-05-15)The pollen beetle Meligethes aeneus (Fabricius) (Col.: Nitidulidae) is one of the most important pests of oilseed brassicas in Europe. Due to extensive use of pyrethroids and the limited supply of registered insecticide ... -
Analysis of toxigenic fungi and their mycotoxins in biotic interactions
(2014-02-12)Filamentous fungi are producers of a broad range of secondary metabolites with a high diversity of biological activities. It is generally assumed that the production of these metabolites leads to benefits which allow the ... -
Fusarium-Artenspektren an Halmbasis und Körnern von Weizen in unterschiedlichen Weizenfruchtfolgen
(2013-12-03)In the present study the composition of Fusarium species spectra on stem bases and grains of wheat and their colonization rates were investigated under the conditions of a wheat crop rotation experiment existing since 2006. ... -
New Strategies for the Detection of <i>Fusarium</i> Infection and Mycotoxin Contamination of Cereals and Maize
