Nitrogen signalling in Arabidopsis thaliana
… nitrogen-regulated transcription factor genes in Arabidopsis that may control N-use efficiency we developed a unique resource for qRT-PCR measurements on all Arabidpsis transcription factor genes. Using closely spaced, gene-specific primer pairs and SYBR® Green to monitor amplification of …

Protein phosphorylation regulation in Arabidopsis
… phosphorylation and dephosphorylation. In Arabidopsis, both protein kinases and protein phosphatases exist as large protein families. Here the recent progress in understanding the roles of plant protein phosphatases and mitogen-activated protein kinases (MAPKs) is reviewed. To further …

Engineering cyanide-tolerant Arabidopsis thaliana
… some success, to increase cyanide tolerance in Arabidopsis by genetic engineering: the first, by augmenting the β-cyanoalanine synthase pathway using a microbial nitrilase; and, the second, by introducing a microbial detoxification pathway targeted to the chloroplasts while overexpressing the …

An Analysis of the Arabidopsis Aquaporin TIP1;1 and Analysis of Stress Response Signaling in Arabidopsis
The stress response pathways in Arabidopsis were studied, using publically available Affymetrix ATH1 microarray data. The salt stress signaling pathways were dissected, by comparing the salt stress response to other abiotic/biotic stress responses or the response to plant hormones. The analysis, …

Untersuchungen zur Metallhomöostase in Arabidopsis thaliana
… Von den zwölf Mitgliedern dieser Familie in Arabidopsis thaliana (A. thaliana) – Metall Toleranz Protein (MTP)-1 bis -12 – wurden bisher AtMTP1 und AtMTP3 charakterisiert. In dieser Arbeit wird die Charakterisierung von AtMTP2 beschrieben. Wie die homologen Proteine AtMTP1 und AtMTP3 führt …

Characterization of ammoniumtransporters in Arabidopsis thaliana
… some genes had partially been characterised in Arabidopsis (Gazzarrini et al., 1999; Sohlenkamp et al. 2002; Kaiser et al., 2002). However, these studies were not sufficient to assign physiological functions to the individual transporters and AMT1.4 and AMT1.5 had not been studied prior to this …

Amino Acid Transporters in Arabidopsis Thaliana
… LHT1 and ART1, were identified from the Arabidopsis EST cDNA library by complementation. LHT1 is a lysine and histidine transporter, and ART1 is an arginine and aromatic amino acid transporter. ART1 seemed to possess transport activity for IAA and other aromatic amino acid derivatives. …

Dissecting SBDS function in Arabidopsis thaliana
… maturation and function. Interestingly, the Arabidopsis thaliana SBDS (AtSBDS) protein has a unique C-terminal zinc finger extension that distinguishes it from homologues in other organisms. This research aims to elucidate the role of the SBDS protein in plants, with a particular focus on …

Dissection of Drought Responses in Arabidopsis
… abiotic stress gleaned from extensive studies in Arabidopsis has provided much information on the complex processes underlying plant response to abiotic stresses. Nevertheless, there is a need for integration of the knowledge gained and a systematic molecular genetic dissection of the complex …

Regulation of Rubisco in Arabidopsis Thaliana Rca(-) Complemented With Arabidopsis Rubisco Activase Engineered at an ATP Binding Site
… the results suggested that the 46kD isoform of Arabidopsis Rubisco activase may be a light regulatory component of Rubisco activation.

Characterization of six Arabidopsis AROGENATE DEHYDRATASE promoters
… are six different isoenzymes encoded by the Arabidopsis genome. All six have specialized roles within the plant, and are differentially expressed during development and under stressful conditions. To deduce the specialized role of each ADT, unique patterns of regulatory motifs were identified …

Regulation of ethylene receptor expression in Arabidopsis
<p>The ethylene receptor family of Arabidopsis consists of five members, ETR1, ETR2, ERS1, ERS2, and EIN4. Regulation of ethylene receptor expression in Arabidopsis was studied using three different approaches. First, the effect of ethylene-pathway mutations upon expression of ETR1 was examined. …

Zelltyp-spezifische Mikroanalyse von Arabidopsis thaliana-Blättern
… Arbeit entwickelten und auf die Modellpflanze Arabidopsis thaliana angewandten Einzelzellanalysetechniken erlauben es in Zukunft, physiologische Prozesse besser sowohl räumlich als auch zeitlich aufzulösen. Dies wird zu einem detaillierteren Verständnis mannigfaltiger Vorgänge wie …

Expressionsprofile von ABC-Transportern in Arabidopsis thaliana
… beteiligt ist. In der Modellpflanze Arabidopsis thaliana wurden 103 ABC-Transportergene annotiert, die sich in 9 Subfamilien aufteilen. Experimentell nachgewiesen wurden bisher lediglich 6 Mitglieder aus 2 Subfamilien. In dieser Arbeit wurden 28 ABC-Transporter aus 6 Subfamilien, …

Understanding and engineering photoresponses in Arabidopsis thaliana
… of phototropins in the circadian system of Arabidopsis. This study shows that in mutant plants lacking functional phototropins, the lack of phototropin function has little effect upon circadian rhythms of luciferase bioluminescence but is sufficient to induce loss of robustness in rhythms of …
