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
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
Magnesium (Mg) deficiency, a widespread yet overlooked problem in agriculture, has been reported to retard plant growth and development, through affecting key metabolic pathways. However, the metabolic responses of plant to Mg deficiency is still not fully understood. Here we report a metabolomic
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
Oxylipins of the jasmonate pathway and synthetic functional analogs have been analyzed for their elicitor-like activities in an assay based on the induced accumulation of glyceollins, the phytoalexins of soybean (Glycine max L.), in cell suspension cultures of this plant. Jasmonic acid (JA) and its
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,
Cultivated soybean (Glycine max) carrying the Rj2 allele restricts nodulation with specific Bradyrhizobium strains via host immunity, mediated by rhizobial type III secretory protein NopP and the host resistance protein Rj2. Here we found that the single isoleucine residue I490 in Rj2 is required
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, <i>Bacillus
