Analyse des Transkriptionsfaktors TGA2.1 aus Nicotiana tabacum
(2002-04-02)The thesis explores the possible function of the plant transcription factor TGA2.1. For this purpose genetically modified plants were generated in which a) TGA2.1 was ectopically overexpressed ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
Der bZIP-Transkriptionsfaktor BZI-1 aus Nicotiana tabacum: Analyse der in vivo Funktion durch Modulation der BZI-1- Aktivierungseigenschaften in transgenen Pflanzen
(2002-06-12)The tobacco (Nicotiana tabacum) bZIP protein BZI-1 exhibits all typical characteristics of a transcription factor. BZI-1 binds to G-box and C-box cis-elements in vivo, and the N-terminus ... -
Characterization of an Arabidopsis glutaredoxin that interacts with core components of the salicylic acid signal transduction pathway
(2006-05-16)Salicylic acid (SA) is a plant signalling molecule that mediates the induction of defense responses upon attack by a variety of pathogens. Activation sequence-1 (as-1) type cis elements 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 ... -
Charakterisierung der konservierten Domänen des Transkriptionsfaktors N.t.BZI-1
(2002-05-15)The conserved domains of the transcriptional regulator BZI-1 are defined by the homology to related transcriptionfactors. The specific function of different domains is mediated by the modular ... -
Charakterisierung von zwei Arabidopsis thaliana Mutanten mit erhöhter PR1-Expression
(2006-08-15)One of the main components of the plant defense response during an infection is the raise of endogenous salicylic acid levels which leads to an increased expression of defense genes. ... -
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 ... -
Etablierung und Anwendung der Chromatin-Immunopräzipitation für <i>in vivo</i>-Bindungsstudien der bZIP-Transkriptionsfaktoren TGA2.1 und TGA2.2 an Promotoren der Pathogenabwehr in Tabak
(2005-11-25)The as-1 element, originally found in the Cauliflower Mosaic virus, is inducible by salycylic acid, auxin and also by pathogen attack. Several as-1-like elements were also found in plant ... -
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 ... -
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. ... -
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 ... -
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 ... -
