OBJECTIVE Water is an increasingly scarce resource that limits crop productivity in many parts of the world, and the frequency and severity of drought are predicted to increase as a result of climate change. Improving tolerance to drought stress is therefore important for maximizing future crop

Total pyridine nucleotide concentration of root tissue for young soybean (Glycine max var. Bansei) and sunflower (Helianthus annuus L. var. Mammoth Russian) plants is the same with either ammonium or nitrate, but nitrate results in an increased proportion of total oxidized plus reduced NADP

The aim of this study was to reveal the pyridine metabolism in leaves of two mangrove legumes, Derris indica (= Millettia pinnata or Pongamia pinnata) and Caesalpinia crista. Radioactivity from [carbonyl-14C]nicotinamide supplied exogenously to young leaf disks was recovered in nicotinic acid,

Enzymatic regulation of pyricline nucleotide formation, under symbiotic and non-symbiotic conditions, was analyzed using soybeans (Glycine max L. cv. 'Akisengoku') and rhizobia (Bradyrhizobia japonicum strain A1017), respectively. It was found that levels of pyridine nucleotides in bacteroids in

A soluble enzyme which catalyzes the transfer of the methyl group from S-adenosyl-L-methionine to the nitrogen atom of pyridine-3-carboxylic acid (nicotinic acid) could be detected in protein preparations from heterotrophic cell suspension cultures of soybean (Glycine max L.). Enzyme activity was

Hemoprotein derivatives of an abundant soybean (Glycine max Merr.) root nodule leghemoglobin, Lba, were studied for their modified spectral characteristics and physical properties. Three modified hemoprotein derivatives of Lba (Lbam1, Lbam2, and Lbam3) were purified by preparative isoelectric

This research intended to analyze the expression pattern of proteins in roots of the Brazilian soybean cultivar Conquista when inoculated with Bradyrhizobium japonicum CPAC 15, a strain broadly used in commercial inoculants in Brazil. At ten days after bacterial inoculation, whole-cell proteins were

One attractive strategy to discover more active and/or crop-selective herbicides is to make structural changes to currently registered compounds. This strategy is especially appealing for those compounds with limited herbicide resistance and whose chemistry is accompanied with transgenic tools to

Ferric leghemoglobin reductase (FLbR), an enzyme reducing ferric leghemoglobin (Lb) to ferrous Lb, was purified from cowpea (Vigna unguiculata) root nodules by sequential chromatography on hydroxylapatite followed by Mono-Q HR5/5 FPLC and Sephacryl S-200 gel filtration. The purified cowpea FLbR had

Substantial amounts of NO3 from agricultural crop production systems on poorly drained soils can be transported to surface water via subsurface drainage. A field study was conducted from the fall of 1993 through 2000 on a tile-drained Canisteo clay loam soil (fine-loamy, mixed, superactive,

Subsurface drainage, a water management practice used to remove excess water from poorly drained soils, can transport substantial amounts of NO3 from agricultural crop production systems to surface waters. A field study was conducted from the fall of 1986 through 1994 on a tile-drained Canisteo clay

A cDNA encoding soybean (Glycine max [L.] Merr) ferric leghemoglobin reductase (FLbR), an enzyme that is postulated to play an important role in maintaining leghemoglobin in its functional ferrous state, has been cloned and characterized. A group of highly degenerate oligonucleotides deduced from

We previously cloned and sequenced a cDNA encoding soybean ferric leghemoglobin reductase (FLbR), an enzyme postulated to play an important role in maintaining leghemoglobin in a functional ferrous state in nitrogen-fixing root nodules. This cDNA was sub-cloned into an expression plasmid, pTrcHis C,

Nodule ferric leghemoglobin reductase (FLbR) and leaf dihydrolipoamide reductase (DLDH) belong to the same family of pyridine nucleotide-disulfide oxidoreductases. We report here the cloning, expression, and characterization of a second protein with FLbR activity, FLbR-2, from soybean (Glycine max)
