Alanine aminotransferase (AlaAT) catalyses the reversible conversion of pyruvate and glutamate into alanine and oxoglutarate. In soybean, two subclasses were identified, each represented by two highly similar members. To investigate the role of AlaAT during hypoxic stress in soybean, changes in
Ferric citrate induces ferritin synthesis and accumulation in soybean (Glycine max) cell suspension cultures [Proudhon, Briat & Lescure (1989) Plant Physiol. 90, 586-590]. This iron-induced ferritin has been purified from cells grown for 72 h in the presence of either 100 microM- or 500
In plants, proteins of the β-substituted alanine synthase (BSAS) enzyme family perform a diverse range of reactions, including formation of cysteine from O-acetylserine and sulfide, detoxification of cyanide by its addition to cysteine, the breakdown of cysteine into pyruvate, ammonia, and sulfide,
Bacteroids in ineffective (nitrogenase negative) nodules of Glycine max, infected with Rhizobium japonicum 61-A-24, as compared to those in effective nodules are characterized by reduced specific activities of alanine dehydrogenase to 15%, of 3-hydroxybutyrate dehydrogenase to 50%, and an increase
Soybean (Glycine max [L.] Merr) leaves contain a low level (0.05 micromole per gram fresh weight) of gamma-aminobutyric acid (Gaba) but the concentration of this non-protein amino acid increased to 1 to 2 micromoles per gram fresh weight within 5 minutes after transfer of plants or detached leaves
Radioactive photosynthetic assimilates, translocated to a soybean (Glycine max [L.] Merr. ;Fiskeby V') pod can be measured directly by excising the stylar tip of the pod under 20 mm ethylenediaminetetraacetate solution (pH 7.0) and allowing the material to leak into the solution. Pods at the source
When detached soybean Glycine max (L.) Merr. cv. Hark, nodules assimilate [(13)N]N(2), the initial organic product of fixation is glutamine; glutamate becomes more highly radioactive than glutamine within 1 minute; (13)N in alanine becoms detectable at 1 minute of fixation and increases rapidly
Unlike animals which accumulate glutathione (gamma-glutamyl-L-cysteinyl-glycine) alone as their major thiol antioxidant, several crops synthesize alternative forms of glutathione by varying the carboxy residue. The molecular basis of this variation is not well understood, but the substrate
The study investigated the protective effects of kaempferol galactoside (KG) components in mice, which were separated from Jindai soybean leaves (JDL) and mainly composed by two kaempferol galactosides. Further, KG-related metabolites in serum of mice were identified by Tof-MS. Results showed that
A simple and reliable method for the determination of NH4+, K+, Na+, aspartic acid, asparagine, glutamine, and alanine by ion chromatography has been developed. It is suitable for monitoring changes of nitrogen metabolism in soybean because it can accurately measure concentrations o asparagine and
C-Glucosyltransferase is an enzyme that mediates carbon-carbon bond formation to generate C-glucoside metabolites. Although it has been identified in several plant species, the catalytic amino acid residues required for C-glucosylation activity remain obscure. Here, we identified a
The aim of the work reported here was to ascertain that the patterns of labeling seen in isolated bacteroids also occurred in bacteroids in intact nodules and to observe early metabolic events following exposure of intact nodules to (14)CO(2). Intact nodules of soybean (Glycine max L. Merr. cv
Mungbean yellow mosaic India virus (MYMIV) is a bipartite Geminivirus, which causes severe yield loss in soybean (Glycine max). Considering this, the present study was conducted to develop large-scale genome-wide single nucleotide polymorphism (SNP) markers and identify potential markers linked with
When French bean (Phaseolus vulgaris) plants were depodded in the early stages of fruit development, relative levels of a specific protein with a relative molecular weight of 28,000 were enhanced in the young pods that formed later. The protein, designated pod storage protein (PSP), was purified
We have increased the contents of several amino acids in the seeds of Arabidopsis thaliana by introduction of aspartate aminotransferase (AAT), an enzyme of the aspartate biosynthetic pathway. mRNA was prepared from one-week-old seedlings of Glycine max cv. enrei and the cDNA encoding AAT5 was
