TLDR
An endogenous elicitor of the phytoalexin of soybean, was synthesized by way of highly stereoselective glycosylations that involved Glycosyl fluorides as the donors and oxidation of the twelve primary hydroxyl groups in the alpha-(1----4)-linked galactododecaoside derivative.About:

Tansley Review No. 86 Accumulation of phytoalexins: defence mechanism and stimulus response system.
TL;DR: Transgenic and mutant plants with specific alterations in one or more ot those elements necessary for the plant to respond to the signals for phytoalexin synthesis and other defence responses, are beginning to aid resolution of the complex pattern ot signalling events and the respective roles of the inducible defence mechanisms in resistance.

In vitro synthesis of cellulose and related polysaccharides
TL;DR: In this paper, in vitro synthesis of cellulose and related polysaccharides, in which polymer synthesis using an isolated enzyme as catalyst (enzymatic polymerization) as the major part and conventional chemical synthesis are described.

TL;DR: In this paper, the use of 1-thioglycosides has been investigated for the assembly of acidic and zwitterionic polysaccharides of bacterial origin, using suitably protected 1-THIoglycoside residues.

Chemical Synthesis of Oligosaccharides related to the Cell Walls of Plants and Algae
TL;DR: This Review contains an overview of those plant and algal polysaccharides that have been elucidated to date, and detailed summaries of the chemical syntheses of oligosaccharide fragments of cellulose, hemicellulose, pectin, and arabinogalactans, as well as glycans unique to algae.

Structural Requirements of Synthetic and Natural Product Lipo-Chitin Oligosaccharides for Induction of Nodule Primordia on Glycine soja
TL;DR: It is demonstrated that synthetic analogs of natural product Nod factors have the same biological activities and plant responses demonstrate an interdependence of backbone length and the presence of substitutions on the reducing end.

New method for quantitative determination of uronic acids
TL;DR: A new method for determination of uronic acids with meta-hydroxydiphenyl is introduced, which is simpler, quicker, more sensitive, and more specific than other methods, and it needs lesser amounts of fluid.

Oxidation of alcohols by “activated” dimethyl sulfoxide. a preparative, steric and mechanistic study
Kanji Omura,Daniel Swern +1 more
TL;DR: In this paper, the oxidation of primary, secondary, allylic, benzylic, hindered and bicyclic alcohols with dimethyl sulfoxide (DMSO) activated by numerous electrophiles was studied: yields of carbonyls, byproducts and recovered alcohols were quantitatively determined.
Journal ArticleDOI
Structure and function of the primary cell walls of plants.
TL;DR: All glycosyl residues (except the residue at the reducing end of an oligosaccharide, which is called a glycose residue) are glycosidically linked at C-l and this fact is assumed in the notation used, and, thus, C-\ is not mentioned.

PHYTOALEXINS AND THEIR ELICITORS-A Defense Against Microbial Infection in Plants
Alan G. Darvill,Peter Albersheim +1 more
TL;DR: Evidence is presented which supports the view that accumulation of phytoalexins at the site of attempted infection in plants is supported and a hypothesis is presented that suggests that all of the abiotic and some of the biotic elicitors stimulate phy toalexin accumulation by causing the release of an endogenous elicitor from the cell walls of plants.
