(2017-03-21)The present study was part of the international PLANT-KBBE III – joint research project MONARCH (White Mold Brassica napus Resistance Challenge, subproject B). The project assignment included the identification of new ... -
Plant Root Exudates
(2017-02-09)Root exudates represent complex mixtures of low-molecular-weight and high-molecular-weight compounds. The former comprise predominantly primary and secondary plant metabolites, the latter mucilage precursors and some ... -
Effect of mycotoxin production on interactions between Fusarium species during maize infection and on the production of volatile metabolites
(2017-02-02)Maize (Zea mays L.) is an important cereal crop which provides staple food for humans and livestock. Maize cultivation is threatened by numerous microbial diseases under field conditions. Fungal pathogens belonging to ... -
Biological Detoxification of Enniatins
(2017-01-09)Summary: Mycotoxins are secondary metabolites produced by fungi. Enniatins are a group of cyclohexadepsipeptides made of three hydroxyisovaleric acid molecules and alternating amino acids mostly valine, leucine and isoleucine. ... -
Studies on Resistance of Oilseed Rape (Brassica napus) to Verticillium longisporum – Interaction with Drought Stress, Role of Xylem Sap Modulations and Phenotyping Under Controlled and Field Conditions
(2016-11-25)Oilseed rape (Brassica napus) is one of the most important sources of vegetable oil in the world. Due to the growing demands in the biodiesel industry in particular, the global OSR production is gradually increasing since ... -
Root exudation pattern of sugar beet (Beta vulgaris L.) as influenced by light intensity and P deficiency
(2016-07-28)Sugar beet is known as a P uptake efficient plant species due to its ability for increasing P availability in soil. This is done by changing rhizosphere chemistry through exudation of e.g. citric, malic, oxalic, citramalic ... -
Differential interaction of Magnaporthe grisea and Fusarium graminearum with ears of wheat cultivars varying in resistance
(2015-11-24)The inoculation system for M. grisea and F. graminearum in a controlled environment was established. Twenty-seven wheat cultivars were used to optimize the inoculation. The cultivar Milan exhibited the highest resistance ... -
Exploring the interactions of bacterial secondary symbionts (BSS) in wheat aphids, Sitobion avenae F. with parasitoids
(2015-11-20)Bacterial secondary symbionts (BSS) are renowned for their capacity to protect their hosts against natural enemies. Sitobion avenae (F.) is recently reported for Hamiltonella defensa and Regiella insecticola infections. ... -
Elimination of Clavibacter michiganensis subsp. michiganensis from tomato cultures and seeds by highly sensitive detection methods and effective seed treatments
(2015-09-04)The phytopathogenic bacterium Clavibacter michiganensis subsp. michiganensis (Cmm), causing bacterial canker of tomato, is the most serious bacterial pathogen of tomato worldwide. The bacterium is considered as A2 ...

Colonization pattern of crop plants by endophytic fungi
(2015-06-16)Endophytes are fungi or bacteria occurring inside plant tissues without causing any apparent symptoms in the host plants. Fungal endophytes are quite common in nature; some of them are able to work as bio-control agents ... -
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 ... -
Secondary metabolites in fungal biotic interactions
(2014-05-22)Fungi are known for their production of chemical and biological diversity of secondary metabolites. To understand the structure, biological activity and function of fungal secondary metabolites contribute to the development ... -
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 ... -
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. ... -
Methodical improvements in microspore culture of Brassica napus L.
(2013-11-05)The utilisation of microspore in vitro culture and chromosome doubling for production of homozygous and doubled haploid plants is an important issue in modern breeding programs. Nevertheless, insufficient Colchicine induced ... -
