NADP+-isocitrate dehydrogenase (NADP+-IDH; EC 1.1.1.42) is involved in the supply of 2-oxoglutarate for ammonia assimilation and glutamate synthesis in higher plants through the glutamine synthetase/glutamate synthase (GS/GOGAT) cycle. Only one NADP+-IDH form of cytosolic localization was detected
Cytosolic NADP(+)-linked isocitrate dehydrogenase (NADP(+)-IDH) is considered the main enzyme catalyzing the production of 2-oxoglutarate for amino acid biosynthesis in plants. We characterized a full-length cDNA encoding the cytosolic NADP(+)-IDH in the gymnosperm Pinus pinaster Ait. The deduced
Cytosolic NADP+-isocitrate dehydrogenase (ICDH) is one of the major enzymes involved in the production of 2-oxoglutarate for amino acid biosynthesis in plants. In most plants studied, ICDH is encoded by either one gene or a small gene family, and the protein sequence has been highly conserved during
The changes of isocitrate lyase levels with respect to the catabolism of triglycerides have been studied during the germination of Pinus pinea seeds. We studied the effects of octanoate, oleate, and inhibitors of protein synthesis on isocitrate lyase during germination. Pyruvate kinase,
This work inserts in the research field regarding the effects of altered gravity conditions on biological plant processes. Pinus pinea seeds germination was studied in simulated microgravity (2x10-3g) and hypergravity (20g) conditions. The effects of simulated gravity were evaluated
Advances in analytical methodology for speciation of manganese in pine nuts are presented in this work. The approach is based on the use of orthogonal chromatographic systems, namely size-exclusion chromatography (SEC) of the extracts and strong anion exchange (IEC) of the fractions collected by the
We report the molecular characterization and functional analysis of a gene (PsdeltaOAT) from Scots pine (Pinus sylvestris) encoding Orn-delta-aminotransferase (delta-OAT; EC 2.6.1.13), an enzyme of arginine metabolism. The deduced amino acid sequence contains a putative N-terminal signal peptide for
Sodium pheophorbide a (SPA) is a new alternative fungicide with low toxicity and high efficiency, which has high fungicidal activity against Pestalotiopsis neglecta, a pathogen that causes black spot needle blight of Pinus sylvestris var. mongolica. To utilize SPA for plant disease control,
The inheritance patterns of the chloroplast genomes of shortleaf pine ( Pinus echinata Mill.), loblolly pine ( Pinus taeda L.) and slash pine ( Pinus elliottii Engelm.) were investigated through the trnL-trnF intergenic spacer polymorphism analysis. The DNA sequences of this spacer differ among
