Analysis of the JA-Ile-independent function of COI1 in Arabidopsis thaliana upon infection with Verticillium longisporum
(2021-09-24)CORONATINE INSENSITIVE 1 (COI1) perceives the plant hormone jasmonoyl-isoleucine (JA-Ile) together with proteins of the JASMONATE ZIM-domain (JAZ) family. JA-Ile induces signalling cascades in defence and developmental ... -
Functional analysis of the Arabidopsis thaliana glutaredoxin ROXY9
(2019-05-24)Glutaredoxins are nearly ubiquitious small enzymes which protect the thiol groups of cellular proteins from oxidative stress, contribute to iron-sulfur cluster biogenesis or regulate protein activities via redox modification. ... -
Funktionale Analyse des CC-Typ Glutaredoxin ROXY19 in Arabidopsis thaliana
(2019-02-05)Glutaredoxins are small widespread enzymes that are characterized by the so-called thioredoxin fold. They have an active center which can be reduced by glutathione. The glutaredoxins are divided into three classes according ... -
Plant-specific glutaredoxin ROXY9 regulates hyponastic growth by inhibiting TGA1 function
(2017-04-04)In the rosette plant Arabidopsis thaliana, different environmental cues trigger upward (hyponastic) leaf movement which is evolutionary beneficial when it comes to avoid shading by neighboring plants. Hyponasty results ... -
Analysis of the transcriptional repressor function of Arabidopsis glutaredoxin ROXY19
(2016-02-25)Glutaredoxins (GRXs) are small ubiquitous proteins that are characterized by a thioredoxin (TRX) fold and a glutathione (GSH) reducible active site, which is a CPYC motif in class I GRXs and a CGFS motif in class II GRXs. ... -
Evolution and epigenetic regulation of RNA-mediated duplicated genes in Arabidopsis
(2015-06-16)Gene duplications allow for protein functional diversification and accelerate genome evolution. Occasionally, the transposon amplification machinery reverse-transcribes mRNA of a gene, integrates it into the genome and ... -
Characterization of Clade I TGA Transcription Factors in Arabidopsis thaliana with Respect to Biotic Stress
(2015-04-14)Activation of the plant immune system after pathogen attack involves massive transcriptional reprogramming. In Arabidopsis thaliana, clade I TGA transcription factors (TFs) TGA1 and TGA4 have been shown to contribute to ... -
Transkriptionelle Regulation des pflanzlichen Detoxifikationsprogramms durch das GRAS-Protein SCL14
(2015-03-31)In plants, the contact with toxic substances activates a group of genes, which are involved in the detoxification of these substances. A subgroup of these genes is regulated by the transcriptional coactivator Scarecrow-like ... -
Identification of the role of Arabidopsis ATAF-type NAC transcription factors in plant stress and development
(2014-05-14)In higher plants, xenobiotic chemicals induce transcriptional activation of genes involved in their detoxification. A generally accepted concept explaining gene regulatory networks is that, activation of pre-existing ... -
The role of defense signaling pathways in the interaction of Arabidopsis thaliana and Vertcillium longisporum
(2013-08-26)Verticillium longisporum is a soil-borne fungal pathogen causing vascular disease predominantly in oilseed rape. The pathogen enters its host through the roots and maintains a parasitic life stage in the xylem before ... -
Arabidopsis thaliana class II TGA transcription factors provide a molecular link between salicylic acid and ethylene defense signalling
(2011-11-15)Since plants are exposed to a multitude of different attackers, a complex innate immune system has evolved to protect them from devastating diseases. Depending on the type of pathogen or ... -
Regulation of the Cytochrome P450 Gene, CYP81D11, in Arabidopsis thaliana, Subjected to Chemical Stress
(2011-10-17)In higher plants, toxic chemicals induce the expression of a set of detoxification genes. In Arabidopsis thaliana, transcriptional activation of a subset of these depends on Class II TGA ... -
The Role of Arabidopsis Class-II TGA Transcription Factors in PAMP-mediated Defense Responses
(2010-09-13)The redundant class-II TGA transcription factors TGA2, TGA5 and TGA6 are important activators of SA-induced defense response. In this thesis, the influence of class-II TGA factors in ... -
Functional Analysis of the Salicylic Acid-Responsive PR-1 Promoter in Arabidopsis thaliana
(2010-02-04)The Arabidopsis PR-1 gene belongs to a subset of genes upregulated during systemic acquired resistance (SAR), a plant defense response against a broad spectrum of pathogens mediated ... -
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 ... -
Analyse zweier differentiell regulierter Terpensynthasen in <i>Arabidopsis thaliana</i>
(2008-09-05)Volatiles play an important role in plant-plant and plant-insect interactions and plants can emit different volatile bouquets to communicate with their environment. Thus, it can be ... -
Verticillium longisporum induced gene expression in Arabidopsis thaliana
(2008-09-05)Verticillium longisporum is a soil-borne fungal pathogen causing vascular disease predominantly in oilseed rape. The pathogen enters its host through the roots and maintains a parasitic ... -
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 ... -
