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 ... -
Studies on Ramularia Leaf Spots on Barley - Resistance Phenotyping, Epidemiology and Pathogenicity
(2013-10-31)The deuteromycete, Ramularia collo-cygni (Rcc) has gained increasing importance as the causal agent of a novel leaf spot disease, Ramularia leaf spot (RLS), on barley. The disease occurs conspicuously late in the growing ... -
Improvement of Winter Oilseed Rape Resistance to Verticillium longisporum - Assessment of Field Resistance and Characterization of Ultrastructural Plant Responses
(2013-07-04)Recent years have seen an intensification of oilseed rape (OSR) cultivation, which, together with shorter crop rotations has led to a rapid increase in infestation by the soil-borne vascular pathogen V. longisporum. The ... -
Halmbasis- und Wurzelkrankheitserreger an Weizen (Trititcum aestivum L.) in Energiefruchtfolgen und Bedeutung des Halmbasisbefalls mit Fusarium culmorum (W. G. Smith) Sacc. und Fusarium graminearum (Schwabe) für die Mykotoxin-Kontamination der Pflanze
(2013-04-16)In the present study, the impact of energy crop rotations on stem basis and root pathogens of winter wheat (Triticum aestivum L.) was evaluated by means of a two-way factorial design in field trials conducted at two locations ... -
Determination of fungal gene expression in planta by qRT-PCR and characterization of putative pathogenicity related genes of Verticillium longisporum
(2013-02-26)Genes of Verticillium longisporum potentially involved in the pathogenicity of the fungus were identified in previous studies. The purpose of this work was to characterize some of these genes. Short transcript-derived ... -
Chemical and Genetic Diversity in Sesame (Sesamum indicum L.)
(2012-06-12)Biological diversity exist between species and within species among populations and individuals. Intraspecies diversity has been extensively studied at the genome level but intraspecies diversity in metabolic constitution ... -
Diversity and distribution patterns of foliar fungal endophytes in Theobroma cacao in Central Sulawesi and interactions between endophytes and host plant
(2012-04-24)Tropical plants are colonized by a highly diverse community of fungal endophytes. Factors contributing to fungal endophyte diversity pattern and underlying mechanisms are, however, largely unknown. Interactions between ... -
