cellulose/glycine max

The plant parasitic nematode, Heterodera glycines is the major pathogen of Glycine max (soybean). H. glycines accomplish parasitism by creating a nurse cell known as the syncytium from which it feeds. The syncytium undergoes two developmental phases. The first is a parasitism phase where feeding

A four-stage purification procedure including ammonium sulfate precipitation and ion exchange chromatography on DEAE cellulose has been elaborated for isolation of isocitrate lyase (EC 4.1.3.1) isoforms from the cotyledons of soybean Glycine max L. Electrophoretically homogeneous preparations of two

Transfer RNA from soybean (Glycine max) cotyledons was purified to homogeneity followed by the purification of the family of leucine tRNA via benzoylated diethylaminoethyl cellulose (BDC) chromatography. Nonacylated total purified tRNA was salicylhydroxamate (SHAM) modified by the phenoxyacetyl

Protoplasts isolated from cultured soybean cells (Glycine max (L.) Merr., cv. Mandarin) were used to study polysaccharide biosynthesis during the initial stages of cell wall-regeneration. Within minutes after the protoplasts were transferred to a wall-regeneration medium containing [(14)C]glucose,

A DNA helicase activity was detected in extracts of purified chloroplasts from the SB-1 cell line of Glycine max and partially purified by column chromatography on DEAE cellulose, phosphocellulose, and single-stranded DNA cellulose. The chloroplast helicase has a DNA-dependent ATPase activity, and

Root border cells (BCs) and their associated secretions form a protective structure termed the root extracellular trap (RET) that plays a major role in root interactions with soil borne microorganisms. In this study, we investigated the release and morphology of BCs of Glycine max using light

Protoplasts were prepared from cells of soya-bean (Glycine max) suspension cultures and the plasma membrane was labelled with diazotized [G-3H]sulphanilic acid. Homogenates were fractionated by differential and isopycnic centrifugation, and membrane fractions in a density gradient were characterized

High activities (100-200 micromoles UDP hydrolyzed per milligram chlorophyll per hour) of uridine-5' diphosphatase (UDPase) have been identified in extracts of fully expanded soybean (Glycine max Merr.) leaves. In desalted crude extracts, UDPase activity was strongly inhibited by low concentrations

The major lectin in seeds of a soybean cultivar (Glycine max cv D68-127) has been purified to apparent homogeneity by hydroxyapatite and DEAE-cellulose chromatography. In the latter, the behavior of the lectin was similar to that of the minor isolectins previously described in other soybean

Studies have been conducted with the arginase (l-arginine amidinohydrolase, EC 3.5.3.1) of two legumes: jack bean, Canavalia ensiformis (L.) DC., a l-canavanine-containing plant and soybean, Glycine max, a canavanine-free species. Analyses of the arginase obtained from gradient-purified mitochondria

Two isoenzymes of p-coumarate: CoA ligase were isolated from cell suspension cultures of soybean (Glycine max L., var. Mandarin). Separation and partial purification of the enzymes were achieved by precipitation with MnCl2 and (NH4)2SO4, and column chromatography on DEAE-cellulose, Sephadex G-100

A non-haem iron protein was isolated from an extract of soya-bean nodule bacteroids by a procedure including protamine sulphate and heat precipitation followed by chromatography on DEAE-cellulose. The purified protein contains non-haem iron and acid-labile sulphur and exhibits a spectrum with a

OBJECTIVE The purpose of this study was to analyze the effects of soybean extracts obtained using different extraction methods on the skin of female rats. METHODS A total of 64 female Sprague-Dawley rats were divided into 8 equal groups. Various extracts were administered to the female rats by oral

SBTX, a novel toxin from soybean, was purified by ammonium sulfate fractionation followed by chromatographic steps DEAE-Cellulose, CM-Sepharose and Superdex 200 HR fast-protein liquid chromatography (FPLC). Lethality of SBTX to mice (LD(50) 5.6 mg/kg) was used as parameter in the purification steps.

The nitrogenase system in cell-free extracts of soybean nodule bacteroids was fractionated into 2 components by use of protamine sulfate or polypropylene glycol precipitation followed by chromatography on DEAE-cellulose. Iron and molybdenum were concentrated in 1 fraction and iron in the other.
