A Role for Glycogen Synthase Kinase 3 beta in the Regulation of Glucagon Gene Transcription by Insulin
(2003-11-21)Insulin binding to its receptor on the a-cells in endocrine pancreas initiates a signalling cascade that results in inhibition of glucagon gene transcription. Evidence suggests that the ... -
Analyse der differentiellen Expression von Transportfaktoren und deren Funktion bei dem nukleocytoplasmatischen Transport von TFIIIA
(2002-11-21)In this thesis the nuclear localisation signal (NLS) of the transcription factor IIIA (TFIIIA) was localized within the zinc fingers 3, 4 and 7 to 9. The transport mediating regions are ... -
Analyse der Verticillium longisporum induzierten Seneszenz und Transdifferenzierung in Arabidopsis thaliana
(2011-11-07)Verticillium longisporum (Vl43) is a soil born fungus and its main host is rape (Brassica napus). The main disease symptoms are early senescence, stunting, yellow veins and curled leaves. ... -
Analysen zum subzellulären Lokalisationsverhalten der atypischen Myrosinase PEN2 in Arabidopsis-Mikroben-Interaktionen
(2012-06-27)The atypical myrosinase PEN2 is a molecular component of nonhost resistance in Arabidopsis thaliana. Using a functional GFP-fusion protein revealed the localisation of PEN2 in the periphery of mobile membrane compartments, ... -
Analysis of CERK1 ectodomain shedding and the role of XLG2 in cerk1-4 cell death execution
(2016-05-20)Conserved microbial signatures are perceived via plasma membrane localized pattern recognition receptors (PRRs). In Arabidopsis, perception of the fungal cell wall component chitin requires the LysM receptor-like kinase ... -
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 basic leucine Zipper transcription factors function as quantitative modulators of auxin mediated transcription
(2012-04-10)The essential plant growth hormone auxin orchestrates a wide range of developmental and environmental processes in the course of plant life. In general, these responses are predominately implemented by the encoded activity ... -
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 ... -
Bedeutung der Homöodomäne des Transkriptionsfaktors Pax6 für die Aktivierung des Glukagon-Gens durch Pax6
(2004-09-08)Pax6 is one of the essential transcription factors for activating glucagon gene expression and contains two DNA-binding domains, the paired domain and the homeodomain. In vitro, Pax6 binds ... -
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 ... -
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 ... -
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 ... -
Carbon partitioning in nitrogen-fixing root nodules
(2003-02-28)Nitrogen-fixing root nodules represent strong carbon sinks. Sugar partitioning was studied in three different symbiotic systems, namely a legume, Medicago truncatula, and two actinorhizal ... -
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 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. ... -
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 ... -
