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
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
An N-balance and isotope dilution study was performed to determine the effect of lower gut N supply on N retention and CO(NH(2))(2) kinetics in growing pigs. Nine cecally cannulated and jugular-catheterized barrows (initial BW 22.4 ± 1.2 kg) were randomly assigned to 1 of 3 cecal N infusion
Transfer RNAs and aminoacyl-tRNA synthetases were isolated from 5- and 20-day-old etiolated ageing soybean cotyledons. The relative concentrations of Mg2+ and ATP for optimal acylation (using homologous tRNAs and synthetases) for the 16 amino acids tested indicate that the amino acids can be grouped
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
Heterotrimeric G-proteins and the regulator of G-protein signaling (RGS) proteins, which accelerate the inherent GTPase activity of Gα proteins, are common in animals and encoded by large gene families; however, in plants G-protein signaling is thought to be more limited in scope. For example,
Several hundred soybean [Glycine max (L.) Merr.] cell lines resistant to ethionine were isolated either with or without chemical mutagenesis. of these, 26 were found to contain 2 to 22 times higher than normal levels of uncombined methionine. These 26 cell lines also contained higher than normal
Symbiotically defective auxotrophic mutants were isolated by transposon Tn5 mutagenesis of Rhizobium fredii HH303, a fast-growing microsymbiont of North American commercial soybean cultivars such as Glycine max cv. Williams. Three different Tn5-carrying suicide vectors, pBLK1-2, pSUP1011, and pGS9,
Some d-amino acid (glutamic acid, valine, or leucine) conjugates of 2,4-dichlorophenoxyacetic acid (2,4-D) at 10(-5) molar, stimulated elongation of Avena sativa L. var Mariner coleoptile sections and growth of soybean (Glycine max. L. var Amsoy) tissue as much as did the l-amino acid conjugates at
Soybean (Glycine max L.) is a good source of natural antioxidants and commonly consumed as fermented products such as cheonggukjang, miso, tempeh, and sufu in Asian countries. The aim of the current study was to examine the influence of novel endophytic bacterial strain, Bacillus
