isocitrate dehydrogenase/arabidopsis thaliana

NAD-dependent isocitrate dehydrogenase (IDH) is a Krebs cycle enzyme situated in mitochondria. In Arabidopsis thaliana, five genes encode functional IDH subunits that can be classed into two groups based on gene structure and subunit amino acid sequence. Arabidopsis contains two 'catalytic' and

Two cDNA clones which appear to encode different subunits of NAD(+)-dependent isocitrate dehydrogenase (IDH; EC 1.1.1.41) were identified by homology searches from the Arabidopsis EST database. These cDNA clones were obtained and sequenced; both encoded full-length messages and displayed 82.7%

NADP-dependent (Nicotinamide Adénine Dinucléotide Phosphate-dependent) isocitrate dehydrogenases (NADP-ICDH) are metabolic enzymes involved in 2-oxoglutarate biosynthesis, but they also supply cells with NADPH. Different NADP-ICDH genes are found in Arabidopsis among which a single gene

A proteomic study was conducted to investigate physiological factors affecting feeding behaviour by larvae of the insect, Plutella xylostella, on herbivore-susceptible and herbivore-resistant Arabidopsis thaliana. The leaves of 162 recombinant inbred lines (Rils) were screened to detect genotypes

NADPH is an important cofactor in cell growth, proliferation and detoxification. Arabidopsis thaliana Nudix hydrolase 19 (AtNUDX19) belongs to a family of proteins defined by the conserved amino-acid sequence GX5-EX7REUXEEXGU which has the capacity to hydrolyze NADPH as a physiological substrate in

Cytosolic NADP-dependent isocitrate dehydrogenase (cICDH) produces 2-oxoglutarate (2-OG) and NADPH, and is encoded by a single gene in Arabidopsis thaliana. Three allelic lines carrying T-DNA insertions in this gene showed less than 10% extractable leaf ICDH activity, but only relatively small

NAD-dependent isocitrate dehydrogenase (IDH) is a tricarboxylic acid cycle enzyme that produces 2-oxoglutarate, an organic acid required by the glutamine synthetase/glutamate synthase cycle to assimilate ammonium. Three Arabidopsis (Arabidopsis thaliana) IDH mutants have been characterized,

Glyphosate is a broad-spectrum systemic herbicide used worldwide. In susceptible plants, glyphosate affects the shikimate pathway and reduces aromatic amino acid synthesis. Using Arabidopsis seedlings grown in the presence of 20μM glyphosate, we analyzed H2O2, ascorbate, glutathione (GSH) and

Exogenously applied GABA modulates root growth by inhibition of root elongation when seedlings were grown in vitro on full-strength Murashige and Skoog (MS) salts, but root elongation was stimulated when seedlings were grown on 1/8 strength MS salts. When the concentration of single ions in MS salts

BACKGROUND Trichoderma fungi live in the soil rhizosphere and are beneficial for plant growth and pathogen resistance. Several species and strains are currently used worldwide in co-cultivation with crops as a biocontrol alternative to chemical pesticides even though little is known about the exact

NADP-dependent isocitrate dehydrogenase (NADP-ICDH) is an important enzyme involved in energy metabolism. The complete coding sequence of the pepper (Capsicum annuum) NADP-ICDH gene was amplified using a reverse transcriptase PCR based on the conserved sequence information of the tomato and other

Superoxide dismutases (SODs) are key components of the plant antioxidant defense system. While plastidic and cytosolic isoforms have been extensively studied, the importance of mitochondrial SOD at a cellular and whole-plant level has not been established. To address this, transgenic Arabidopsis
