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 ... -
Phänotypisierung von Raps- und anderen Brassica-Genotypen zur Identifizierung von Resistenzquellen gegenüber Sclerotinia sclerotiorum
(2012-02-28)The aim of this work was the development of suitable screening methods for resistance evaluation of oilseed rape cultivars against S. sclerotiorum. With these methods, possible sources of ... -
Molecular and functional characterization of potential pathogenicity related genes from <i>Verticillium longisporum</i>
(2012-02-17)The genus Verticillium includes many plant pathogenic species that cause serious economic losses through the infection of host plants, and it belong to one of the most widespread groups of ... -
Colonization of maize with Fusarium spp. and mycotoxin accumulation
(2012-01-06)Ear rot caused by Fusarium spp. is a serious disease of maize plants worldwide, which can be divided in two types: Red ear rot or Gibberella ear rot (GER), and Pink ear rot or Fusarium ear rot (FER). Apart from impairment ... -

(2011-07-20)Clavibacter michiganensis subsp. michiganensis is a world wide spread, Gram-positive bacteria that causes the bacterium canker and wilt on tomatoes and mainly infests the xylem vessels of ... -
Interaction of maize root associated fungi and the western corn rootworm
(2011-04-27)Diabrotica virgifera virgifera, the western corn rootworm (WCR), is an invasive root feeding maize pest in Europe, which was accidentally introduced from the USA. The presented thesis is ... -
Einflussfaktoren der Mykotoxinbildung durch Ährenbefall mit Fusarium spp. in verschiedenen Winterweizenfruchtfolgen
(2011-04-07)In the present study agronomic and climatic factors contributing to mycotoxin production in wheat ears by Fusarium spp. were examined under controlled and field conditions. Particular ... -
Regulation der Biosynthese von Sekundärmetaboliten und praktische Nutzung von Pflanzenextraktem am Beispiel von Streptomyces bottropensis und Plasmopara viticola
(2011-02-08)Bacterial and herbal secondary metabolites make up an enormous reservoir of substances which can benefit towards mammalian diseases and protect plants against phytopathogens. While the ... -
The biological role of Fusarium graminearum mycotoxins
(2011-01-27)F. graminearum is an important pathogen that causes head blight and root rot in wheat and ear and root rot in maize. Because of its toxigenic nature most of the diseased crops are found to ... -
