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 studies on the transmembrane protein encoded by the TM20 gene in maize
(2002-05-03)In the course of the analysis of lachrima, a recessive, defective kernel, embryo-lethal mutation in Zea mays that blocks embryo and endosperm development at transition stage, a gene coding ... -
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; ... -
Funktionelle Analyse des Transkriptionsfaktors TGA2.1 aus Nicotiana tabacum: Identifikation von Interaktionspartnern und Charakterisierung transgener Pflanzen mit reduzierter TGA2.1-Menge
(2004-01-26)In higher plants as-1 like cis elements mediate auxin- and salicylic acid-inducible transcription of defence related genes. Originally found in viral and T-DNA promoters, they are also ... -
Funktionelle Analyse von ERF-Transkriptionsfaktoren aus N.tabacum und A.thaliana im Rahmen der Pathogenresistenz
(2003-12-02)Using a Yeast-one-hybrid approach we isolated from a tobacco cDNA library two so far unknown transcription factors. Based on their DNA-binding AP2-domain we grouped them into the family of ERF-proteins and named them NtERF5 ... -
Funktionelle Charakterisierung von apoplastischen Proteinen in Brassica napus und Arabidopsis thaliana nach Infektion mit Verticillium longisporum
(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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Isolation and Characterization of Proteins Interacting with Tobacco Transcription Factor TGA2.2
(2004-07-09)In plants, the as-1 cis-element and its trans-acting factors, known as TGA transcription factors, play an important role in the transcriptional control of salicylic acid- and auxin-inducible ... -
Metabolic fate of jasmonates
(2019-01-21)Jasmonoyl-isoleucine (JA-Ile) is a phytohormone that orchestrates responses to wounding, feeding insects or necrotrophic pathogens in plants. JA-Ile-metabolism has been studied intensively (Wasternack, 2015) and most of ... -
Molecular analysis of importin-α-mediated nucleocytoplasmic signaling in plant innate immunity
(2015-04-30)IMPORTIN-αs are a family of nuclear transport receptors that mediate the translocation of nuclear localization signal (NLS)-containing cargo proteins from the cytoplasm into the nucleus through nuclear pores. The IMPORTIN-α3, ... -
Nebenwege des zentralen Kohlenstoffmetabolismus von Bacillus subtilis: Regulation der Methylglyoxalsynthase und der Zitratsynthase CitA
(2015-09-22)The phosphoenolpyruvate phosphotransferase system plays a crucial role in carbon metabolism of Bacillus subtilis. Besides uptake of different sugars the components of the PTS exert regulatory functions. This also accounts ... -
Ein Netzwerk von heterodimerisierenden C/S1 AtbZIP-Transkriptionsfaktoren und seine Funktion in Seneszenz, Stressantwort und Samenentwicklung
(2006-09-18)Transcription factors of the bZIP (basic region - leucine zipper) family occur in all eukaryotic organisms analyzed so far. bZIP transcription factors bind DNA as dimers, whereby some bZIP ... -
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 ... -
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 ... -
