Plasticity of Primary Metabolism in Parasitic Orobanchaceae
… of this is the relationship between parasite metabolism and the metabolite profile of its host. To what extent does the metabolite profile of the parasite depend on that of the host? Do parasites that differ in host-dependency also differ in their metabolism or do they use common metabolic …

A Metabolomics-Based Analysis of Acyl-Homoserine Lactone Quorum Sensing in Pseudomonas aeruginosa
… the relationship between QS and small molecule primary metabolism, using metabolomic methods based on nuclear magnetic resonance spectroscopy and mass spectrometry. Analysis of extracellular metabolic profiles (the bacteria’s “metabolic footprint”) established that QS can modulate the uptake and …

Physiological, hormonal and metabolic alterations caused by selenium in rice seedlings
… relationships between hormones biosynthesis and primary metabolism during growth of rice (Oryza sativa L.) seedlings is poorly understood. Thus, the hypothesis that Se induces changes in the interactions between auxin and ethylene to modulate primary metabolism and growth of rice seedlings was …

Investigations into the molecular evolution of plant terpene, alkaloid, and urushiol biosynthetic enzymes
… is suspected that enzymes in plant specialized metabolism evolved from those in primary metabolism. Understanding how plants evolved to produce these diverse metabolites is of primary interest, as it can lead to the engineering of plants to be more resistant to both biotic and abiotic stress, or …

Nitrate: metabolism and development
… thesis was to study the effect of nitrate on primary metabolism and in development of the model plant Arabidopsis thaliana. The present work has two separate topics. First, to investigate the GDH family, a small gene family at the interface between nitrogen and carbon metabolisms. Second, to …

Investigating the Role of the VAL1 Transcription Factor in Arabidopsis thaliana Embryo Development
… storage proteins synthesized by the pathways of primary metabolism. Seed development and metabolism are positively regulated at the transcriptional level through the transcription factors belonging to the LAFL regulatory network. The VAL genes encode repressors of the seed maturation program in …

The Role Of The DOMAIN OF UNKNOWN FUNCTION (DUF2358) In Sugar Signalling Pathways In Arabidopsis thaliana
… a key role as signalling molecules to regulate metabolism and development of plants but also play a critical role in response to abiotic stresses such as drought and high salinity . This study was conducted to investigate the role of DUF2358 in sugar signalling pathways under stress conditions …

Paralogous genes in Arabidopsis thaliana contribute to diversified phenylpropanoid metabolism
… fitness remains difficult. Plant specialized metabolism provides an attractive platform to study the fixation of genes post duplication and how this process leads to the chemical diversity seen today. Specialized metabolites by definition are thought to be dispensable under normal growth …

Functional effects of cytochrome P450 variants on drug metabolism and adverse drug reactions: developing and extending high throughput P450 protein technology platforms
… reactions. They are responsible for over 80% of primary metabolism of currently available drugs and are therefore central to its medical importance. Investigating the effects of these enzymes on drugs by metabolite detection and kinetic studies is a step forward to the vision of personalised …

The roles of secondary metabolites in microcystis inter-strain interactions
… is related with several pathways of the primary metabolism. A clear correlation of a microcystin knockout and the SigE-mediated regulation of carbon metabolism is found. According to the acquired transcriptional data, a model is proposed that postulates the regulating effect of …

Microarray Analysis of Soybean Treated With Fusarium Toxin and Development of a Soybean Gene Expression Database
… modification, detoxification, defense response, primary metabolism and membrane transport. To perform expression profile comparisons across experiments, and to handle the large volumes of microarray expression data, an expression database equipped with analysis tools was constructed and a gene …

Context-specific metabolic predictions
… reactions occurring in the cells: the metabolism. These reactions form an intricate network which produces all required chemical compounds, i.e., metabolites, from a set of input molecules. Cells regulate the activity through metabolic reactions in a context-specific way; only reactions …

Identification and characterization of metabolic Quantitative Trait Loci (QTL) in Arabidopsis thaliana
Plants are the primary producers of biomass and thereby the basis of all life. Many varieties are cultivated, mainly to produce food, but to an increasing amount as a source of renewable energy. Because of the limited acreage available, further improvements of cultivated species both with respect …

Short-term dynamics of nano- and picoplankton in the southern Benguela upwelling system
… picoplankton diversity, community structure and primary metabolism varied between the active and relaxation periods of an upwelling cycle. The results highlighted the complexity of picoplankton dynamics in variable environmental settings. However, the question then became whether …

Implications of Microcystin Production in Microcystis aeruginosa PCC 7806
… produce about 40 percent of the world’s primary biomass, but also a variety of often toxic peptides such as microcystin. Mass developments, so called blooms, can pose a real threat to the drinking water supply in many parts of the world. This study aimed at characterizing the biological …

Genetic studies of candidate genes in the glycoalkaloid biosynthetic pathway of potato
… alleles in most of the candidate genes. Genes of primary metabolism (HMG1, HMG2 and SQE) had stronger selection constraints than those in secondary metabolism (SGT1 and SGT2). Sequence polymorphism in HMG2, SQE, SGT1 and SGT2 separated either the phu DH clone which produced no SGAs, or chc 80-1, …

Leaf Volatile Emissions Structure Tree Community Assembly and Mediate Climate Feedbacks in Tropical Forests
… the fates of trees and the atmosphere. Leaf primary metabolism cycles carbon and indirectly drives atmospheric circulation via the latent heat of transpiration. Tropical forests contain half of global forest carbon, and actively cycle carbon and energy year round, making them critical …
