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 …

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 …

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 …

Zelltyp-spezifische Mikroanalyse von Arabidopsis thaliana-Blättern
… K+-Konzentration in verschiedenen Geweben von A. thaliana bestimmt werden. Sie lag in Epidermis und Mesophyll mit ca. 25 mM unterhalb der für andere Pflanzenspezies (Solanum tuberosum und Hordeum vulgare) publizierten Konzentration. Weiter konnte gezeigt werden, daß zwölf freie Aminosäuren mittels …

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 …

The AtMRS2 gene family from Arabidopsis thaliana
… A. Tutone (this laboratory) identified an Arabidopsis thaliana gene by the complementation of a Mg2+-uptake yeast mutant (CM66). This gene, referred to as AtMRS2-11, was expressed as cDNA from a strong yeast promoter and allowed the growth of the CM66 yeast strain on standard media. The …

Coordination of the Arabidopsis thaliana circadian clock
… the clock at the sub-tissue level across entire Arabidopsis thaliana seedlings. Consistent with previous tissue-level studies, our results showed that the clock runs at different speeds (periods) in each organ, which causes the clock to peak at different times across the plant in both constant …

New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens = New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens
… uncharacterized molecular components of Arabidopsis thaliana. Thus, we have demonstrated that A. thaliana secondary cell wall is not just a structural defensive barrier, but is also an important component of specific signalling in defence responses. The broad spectrum resistance of irx1 …

Immunomodulation of Flavonoid Biosynthesis in Transgenic Arabidopsis thaliana
… were isolated from a phage display library using Arabidopsis chalcone isomerase (CHI) of the flavonoid biosynthetic pathway as the antigen. Each of the genes encoding the scFv's was cloned into a plant transformation vector, which was subsequently used to generate transgenic plants. One transgenic …

Metabolic interactions in leaf development in Arabidopsis thaliana
… die Morphologie der Blätter im Modellorganismus Arabidopsis thaliana reguliert werden. Besondere Aufmerksamkeit wurde hierbei der Möglichkeit geschenkt, dass es interne metabolische Signale in der Pflanze geben könnte, die das Wachstum und die Entwicklung von Blättern beeinflussen. Um diese …
