(2011-06-24)Verticillium longisporum is a soil-borne pathogenic fungus which is restricted to the family of Brassicaceae. V. longisporum is a vascular pathogen which colonizes the xylem of its host ... -
Die Rolle der beiden Transkriptionsfaktoren AtbZIP1 und AtbZIP53 aus Arabidopsis thaliana in der Anpassung des pflanzlichen Metabolismus an Energiemangelbedingungen
(2011-02-11)Energy deprivation, induced for example by long periods of darkness, leads to dramatic reprogramming of the plant's metabolism. Macromolecules like proteins, amino acids, fatty acids, ... -
The Arabidopsis C/S1 bacic leucine Zipper transcription factor network:Impact of heterodimer formation on target gene transcription
(2011-01-14)Heterodimerisation of basic leucine zipper (bZIP) transcription factors (TFs) is proposed to play a crucial role in regulation of gene expression. To analyse bZIP heterodimerisation of ... -
Funktionsanalyse der Ankyrin-repeat Proteine AKR2A und AKR2B in Arabidopsis thaliana
(2010-07-01)The ankyrin-repeat protein NtANK1 and the basic leucin zipper (bZIP)-transcription factor NtBZI-1 interact in tobacco. These proteins are involved in auxin-mediated gene activation ... -
Transkriptomanalyse der <i>Arabidopsis</i>-Wurzel nach Infektion mit dem pilzlichen Pathogen <i>Verticillium longisporum</i> und Identifizierung von transkriptionellen Regulatoren der Pathogenantwort
(2010-04-08)Verticillium longisporum is a soil-borne fungal pathogen causing vascular disease within a narrow host range of brassica species. It is a mayor pest in oilseed rape cultivation causing ... -
Identifikation von Zielen und molekulare Charakterisierung des RNA-Bindeproteins XSeb4R in Xenopus laevis
(2009-10-28)While developmental processes have been extensively studied in the context of transcriptional regulation, much less is known about regulation via translational regulation. RNA-binding ... -
The GRAS Protein SCL14 and TGA Transcription Factors Interact to Regulate Stress-Inducible Promoters
(2008-11-12)This work deals with the identification of signal components involved in plants reaction to xenobiotic substances. The regulatory protein Scarecrow-like 14 (SCL14) was identified as a ... -
Funktionale Bedeutung der Protein-Protein Interaktion zwischen dem Tabak Ankyrin-Repeat Protein ANK1 und dem bZIP-Transkriptionsfaktor BZI-1 im Rahmen der pflanzlichen Auxin- und Pathogenantwort
(2008-09-24)The tobacco (Nicotiana tabacum) bZIP transcription factor BZI-1 participates in auxin response and the tobacco mosaic virus (TMV) induced hypersensitive response (Kuhlmann et al., 2003; ... -
Chararcterisation of fungal protein kinases involved in the regulation of the cell cycle of Saccharomyces cerevisiae and of sexual development in Aspergillus nidulans
(2007-11-22)In this work, fungal model organisms, the single cell budding yeast Saccharomyces cerevisiae and the filamentous fungus Aspergillus nidulans were used to characterize different factors ... -
Blue light-dependent development of the filamentous fungus Aspergillus nidulans
(2007-11-22)Numerous studies have revealed that fungal development and the production of secondary metabolites are linked although the molecular mechanisms are yet unknown. Light seems to be one of the ... -
Development of an orthogonal ligand-receptor pair based on synthetic estrogen analogs and engineered estrogen receptor for transcriptional regulation
(2007-05-29)The aim of this dissertation was the development of an inducible gene switch based on a modified human estrogen receptor and non-steroidal estradiol analogs. To that end, an in vivo test ... -
Identifikation und Regulation einer durch Insektenfraß induzierbaren Geranyllinalool-Synthase in Arabidopsis thaliana
(2007-02-12)Volatile secondary metabolites emitted by plants contribute to plant-plant, plant-fungal, and plant-insec communication. The C16-homoterpene TMTT (4,8,12-trimethyltrideca-1,3,7,11-tetraene) is emitted ... -
Die Bedeutung des Proteins Scarecrow-like 14 in der Regulation der Transkription von Stressgenen
(2006-10-23)The cis-regulatory element as-1 of many plant pathogen-related defence genes is inducible by salicylic acid (SA) and auxin. Reactive oxygen species (ROS) seem to be involved. A ... -
