Model-guided Analysis of Plant Metabolism and Design of Metabolic Engineering Strategies
… been constructed for several different microbes, plants, and animal species. Researchers have also developed advanced algorithms to use GEMs to predict genetic modifications for the overproduction of biofuel and valuable commodity chemicals. Many of the predictive algorithms for microbes were …

Probing Plant Metabolism: The Machineries of [Fe-S] Cluster Assembly and Flavonoid Biosynthesis
The organization of metabolism is an essential feature of cellular biochemistry. Metabolism does not occur as a linear assembly of freely diffusing enzymes, but as a complex web in which multiple interactions are possible. Because of the crowded environment of the cell, there must be structured and …

Modeling photosynthesis and related metabolic processes : from detailed examination to consideration of the metabolic context
… related biochemical processes in the context of plant metabolism was dissected by employing modeling approaches ranging from kinetic to stoichiometric models. The Calvin-Benson cycle, as primary pathway of carbon fixation in C3 plants, is the initial step for producing starch and sucrose, …

Expression rekombinanter pflanzlicher Phosphoenolpyruvat-Carboxylasen zur Beeinflussung des Kohlenstoffmetabolismus von Solanum tuberosum
… (PEPC) is a ubiquitous cytosolic enzyme in plants. Besides several housekeeping functions in plant metabolism, PEPC plays a cardinal role in the initial fixation of CO2 in C4 and CAM plants. The goal of this work was to regenerate transgenic C3-plants (Solanum tuberosum) with enhanced PEPC …

Polyamine metabolism in Arabidopsis: Transgenic manipulation and gene expression
<p>The metabolism of polyamines (Putrescine, Spermidine and Spermine) in wild type and transgenic Arabidopsis thaliana (Col 0 ecotype) plants was studied using the techniques of transgenic manipulation and gene expression. Two specific objectives were: (1) To study the effects of inducible and …

Functional genomics through metabolite profiling and gene expression analysis in Arabidopsis thaliana
… of the most important goals for the community of plant biologists is to take full advantage of the knowledge generated by the Arabidopsis thaliana genome project, and to employ state-of-the-art functional genomics techniques to assign function to each gene. This will be achieved through a complete …

The pathway of nitrogen assimilation in Datura stramonium L
… concerning the assimilation of nitrogen into plant metabolism has been presented. The pathway of nitrate-N assimilation into amino compounds by the leaves and roots of Datura stramonium at different nitrate feeding levels has been investigated using 15N tracer experimentation, enzyme inhibitor …

Characterization of signaling pathways underlying key growth and development processes in Populus trichocarpa
… abiotic stress which can force major changes in plant metabolism and nutrient mobilization. ABA, a prominent plant phytohormone with known roles in the adaptation to stress has shown novel connections in the regulation of growth promoting complexes such as TOR through antagonistic regulatory …

Investigating the Mechanics and Chemistry of Sickle Polish Development
… gloss were examined. High moisture content plants create thick, smooth fields of polish with undulating, billowing margins at a higher developmental speed. Low moisture content plants generate thin, scratch fields of polish with flat, tapering margins at a lower developmental speed. The …

Characterization of the amino acid transporter AAP1 in Arabidopsis thaliana
Amino acids are essential molecules in plant metabolism. Amino acids carry reduced nitrogen while serving as precursors for protein synthesis and secondary metabolites. Translocation of amino acids in the cell is mediated by amino acid transporters. While about 100 transporters have been …

Gene expression profiling in different stages of development of Arabidopsis thaliana leaftrichomes at the single cell level
… of mutations in these genes on both trichome and plant development as well as on plant metabolism were analysed. As an outcome of this work novel components in the sophisticated machinery of trichome development and cell cycle progression were identified. These factors could integrate hormone …

An investigation of the pathway of nitrogen incorporation into the leaf and root metabolism of Helianthus annuus L
… concerning the assimilation of nitrogen into plant metabolism has been presented. Xylem sap from hydroponically grown and vermiculite- . -3 -3 grown Helianthus annuus fed at 50 µg N cm and 300 ~g N cm feeding level was analysed for nitrate, ammonia, and amino compounds. Nitrate accounted for …

Persistent viruses in Capsicum annuum plants: Understanding the mystery guests
Most work on plant viruses focuses on their pathogenicity, but recent studies suggest viruses may benefit their hosts, at least under some conditions. Plant-infecting viruses of the Partitiviridae and Endornaviridae are transmitted only vertically, via pollen and seed, generally cause no disease …

Characterization and insights into the molecular mechanism of cytokinin-induced priming of plant defenses
Plants have developed several mechanisms to cope with pathogenic challenges. One of these mechanisms, known as defense priming can be effective at reducing susceptibility to pathogens. Compared to unprimed plants, the immune response from primed plants, upon pathogen attack, is much stronger. This …

Identification of pyruvate decarboxylase/indole pyruvate decarboxylase gene family members from Arabidopsis thaliana.
… acid synthase. PDC is a critical enzyme in plant metabolism that regulates energy production especially during periods of anaerobic stress. IPDC has long been proposed as a key enzyme in the biosynthesis of the plant hormone indole-3-acetic acid (IAA) from tryptophan. Six putative …

Eco-physiological and molecular manipulation of leaf-level primary and secondary metabolism by arthropod herbivory
… or by alterations to primary and secondary metabolism. The type of feeding damage depends on the mouthparts of the herbivore and, in part, determines the magnitude and mechanism by which photosynthesis is altered. However, there is a lack of understanding of these effects across model …

In the first study, Sesbania drummondii plants were grown in soil containing 0-10 g/kg Pb(N03)2 for 0-4 weeks, and were assessed for photosynthetic activity, growth, and Pb accumulation at each harvest. It was observed that S. drummondii seedlings were able to tolerate up to 10 g/kg Pb in …
