Separation of the 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatives of simple disaccharides (maltose, cellobiose, gentiobiose, lactose, and melibiose) by affinity capillary electrophoresis was investigated using lectin-containing neutral phosphate buffers, filled in a linear polyacrylamide-coated
Metabolomics is developing as an important functional genomics tool for understanding plant systems' response to genetic and environmental changes. Here, we characterized the metabolic changes of cultivated soybean C08 (Glycine max L. Merr) and wild soybean W05 (Glycine soja Sieb.et Zucc.) under
The zona pellucida glycoconjugate content of several marsupial species was investigated using differential lectin histochemistry. Ovaries from fat-tailed dunnarts, a southern brown bandicoot, grey short-tailed opossums, brushtail possums, ringtail possums, koalas and eastern grey kangaroos were
Lectins are unique proteins of varying biological importance. They are characterized by specific binding to carbohydrate residues, whether monosaccharides, disaccharides or polysaccharides. The sugar heads on the surface of the erythrocyte specify the different blood groups. Lectins, as an antigenic
In the present study carbohydrate residues in taste buds (TBs) and adjacent epithelial formations of a teleostean fish, a frog and the rabbit were detected by means of lectin histochemistry. Biotinylated lectins from Pisum sativum (PSA), Arachis hypogaea (PNA), Dolichos biflorus (DBA), Triticum
Trehalose (alpha-D-glucopyranosyl-1,1-alpha-D-glucopyranoside), a disaccharide widespread among microbes and lower invertebrates, is generally believed to be nonexistent in higher plants. However, the recent discovery of Arabidopsis genes whose products are involved in trehalose synthesis has
Glycopolypeptide (1) carrying the beta-D-Gal-(1-->3)-alpha-D-GalNAc unit as a kind model of asialo-type mucin was synthesized through three steps: enzymatic synthesis of p-nitrophenyl disaccharide glycoside, reduction of the p-nitrophenyl group, and coupling of the amino group with the carboxyl
Crude, Sephadex-filtered extracts of soybean (Glycine max (L.) Merr.) root nodules contained invertase (E.C. 3.2.1.26) activity with pH optima at 5.4 and 7.8, α,α-trehalase (E.C. 3.2.1.28) activity with pH optima at 3.8 and 6.6, and maltase (E.C. 3.2.1.20) activity with a broad pH optimum between
During the first few days of nitrogen fixation activity by soybean (Glycine max (L.) Merr) root nodules, d-chiro-inositol, myo-inositol, sucrose, alpha,alpha-trehalose, and maltose accumulate rapidly and reach concentrations several fold greater than concentrations in other plant organs.
OBJECTIVE
A major reason for the ineffectiveness of legume inoculants in the field is the rapid death of rhizobia because of desiccation. The major purpose of this study was to identify conditions under which alpha,alpha-trehalose would improve survival of Bradyrhizobium japonicum during
