Oligogalacturonide signal transduction, induction of defense-related responses and protection of grapevine against Botrytis cinerea
TLDR
It is suggested that treatment of grapevine with OGA elicits different signalling pathways, which might act in tandem with the oxidative burst to increase grapevine defense responses required for protection against B. cinerea. Expand
Structural features of pectic polysaccharides from the skin of Opuntia ficus-indica prickly pear fruits.
TLDR
The results showed that the water-soluble fraction WSP3 and the EDTA soluble fraction CSP3, consisted of a disaccharide repeating unit, with side chains attached to O-4 of the rhamnosyl residues, which contained highly branched alpha-(1-->5)-linked arabinan and short linear beta-(1 -->4)-linked galactan.

Elicitor and resistance-inducing activities of β-1,4 cellodextrins in grapevine, comparison with β-1,3 glucans and α-1,4 oligogalacturonides
TLDR
CD-incubated leaves challenged with Botrytis cinerea also resulted in a significant reduction of the disease, suggesting that CD could operate via other distinct reaction pathways than betaGlu and OGA. Expand
Characterization of gtf, a Glucosyltransferase Gene in the Genomes of Pediococcus parvulus and Oenococcus oeni, Two Bacterial Species Commonly Found in Wine
TLDR
It is shown that wild or recombinant bacterial strains harboring a functional gtf gene (gtf+) are more resistant to several stresses occurring in wine and exhibit increased adhesion capacities compared to their gtf mutant variants. Expand
Characterization of white wine mannoproteins.
TLDR
Mannoproteins were isolated from white wine through a sequence of operations that consisted of nanofiltration for concentration of macromolecules, polysaccharide precipitation with ethanol, and affinity chromatography on concanavalin A. Expand
Elicitor and resistance-inducing activities of beta-1,4 cellodextrins in grapevine, comparison with beta-1,3 glucans and alpha-1,4 oligogalacturonides.
TLDR
CD-incubated leaves challenged with Botrytis cinerea also resulted in a significant reduction of the disease, suggesting that CD could operate via other distinct reaction pathways than betaGlu and OGA. Expand
A new fermentation process allows large-scale production of human milk oligosaccharides by metabolically engineered bacteria.
TLDR
It is shown that intracellular lactose was efficiently glycosylated when genes of Glycosyltransferase that use lactose as acceptor were expressed and it was also shown that exogenous NeuAc and lactose produced sialyllactose from exogenousNeuAcand lactose. Expand
Large‐Scale In Vivo Synthesis of the Carbohydrate Moieties of Gangliosides GM1 and GM2 by Metabolically Engineered Escherichia coli
TLDR
Two metabolically engineered Escherichia coli strains have been constructed to produce the carbohydrate moieties of gangliosides GM2 and GM1, and exogenously added lactose and sialic acid were shown to be actively internalized into the cytoplasm and converted into GM2 oligosaccharide. Expand
In Plants, 3-O-Methylglucose Is Phosphorylated by Hexokinase But Not Perceived as a Sugar1
TLDR
Investigation of the effects and fate of 3-OMG in heterotrophic plant cells showed that it is not a respiratory substrate and does not contribute to biosynthesis, contrary to the generally accepted idea. Expand
NMR spectroscopy analysis of oligoguluronates and oligomannuronates prepared by acid or enzymatic hydrolysis of homopolymeric blocks of alginic acid. Application to the determination of the substrate
TLDR
The 1H and 13C NMR chemicals shifts of the various saturated and unsaturated timers obtained by acid or enzymatic depolymerisation of homopolymeric blocks of alginates are reported and application of this approach to the analysis of the substrate specificity ofAlginate lyases is discussed. Expand
