Chitosans and pectic polysaccharides both induce the accumulation of the antifungal phytoalexin pisatin in pea pods and antinutrient proteinase inhibitors in tomato leaves
TLDR
The similarity in the induction of synthesis of proteinase inhibitors in tomato cotyledons and of pisatin in pea pods by pecticpolysaccharides and chitosans suggests that the two polysaccharide types may be triggering a similar fundamental system present in peA and tomato plants that regulates the expression of genes for natural protection systems.About:

Food applications of chitin and chitosans
TL;DR: Application of chitinous products in foods and pharmaceuticals as well as processing aids has received considerable attention in recent years as exotic synthetic compounds are losing their appeal.

A Polypeptide from Tomato Leaves Induces Wound-Inducible Proteinase Inhibitor Proteins
TL;DR: It is established that a polypeptide factor can initiate signal transduction to regulate the synthesis of defensive proteins in plant tissues.

Chitin--the undisputed biomolecule of great potential
TL;DR: This most versatile amino polysaccharide, chitin, is surely an undisputed biomolecule of great potential and an unlimited R&D efforts are needed to find new applications, which are necessary to realize its full potential.
Journal ArticleDOI
Production, properties, and some new applications of chitin and its derivatives.
TL;DR: Enzymatic procedures for deproteinization of the shells or mold mycelia and for chitin deacetylation were investigated and show that chit in is resistant to enzymatic de acetylation.

Structure and properties of pectin gels in plant cell walls
TL;DR: The structural characterization of pectins and the gels which they form, in relation to auxin-induced extension growth, the ripening of fruit, and cellular recognition are discussed in this article.

Chitosan as a Component of Pea-Fusarium solani Interactions
Lee A. Hadwiger,Jean M. Beckman +1 more
TL;DR: Chitosan, a polymer of beta-1,4-linked glucosamine residues with a strong affinity for DNA, was implicated in the pea pod-Fusarium solani interaction as an elicitor of phytoalexin production, an inhibitor of fungal growth and a chemical which can protect pea tissue from infection by F. solani f.

Host-Pathogen Interactions: X. Fractionation and Biological Activity of an Elicitor Isolated from the Mycelial Walls of Phytophthora megasperma var. sojae.
TL;DR: In this paper, an elicitor of phytoalexin production in soybean (Glycine max L.) tissues was isolated from purified Phytophthora megasperma var. sojae mycelial walls by a heat treatment similar to that used to solubilize the surface antigens from the cell walls of Saccharomyces cerevisiae.

Host-Pathogen Interactions : XIX. THE ENDOGENOUS ELICITOR, A FRAGMENT OF A PLANT CELL WALL POLYSACCHARIDE THAT ELICITS PHYTOALEXIN ACCUMULATION IN SOYBEANS.
TL;DR: Endogenous elicitors were also solubilized by partial hydrolysis from cell walls of suspension-cultured tobacco, sycamore, and wheat cells, suggesting that galacturonic acid is an essential constituent of the elicitor-active wall fragments.
Xix. the endogenous elicitor, a fragment of a plant cell wall polysaccharide that elicits phytoalexin accumulation in soybeans
TL;DR: In this article, an endogenous elicitor obtained from soybean cell walls binds to an anion exchange resin, which contains oligosaccharides rich in galacturonic acid; small amounts of rhamnose and xylose are also present.

Elicitation of Casbene Synthetase Activity in Castor Bean THE ROLE OF PECTIC FRAGMENTS OF THE PLANT CELL WALL IN ELICITATION BY A FUNGAL ENDOPOLYGALACTURONASE
Robert J. Bruce,Charles A. West +1 more
TL;DR: Treatment of the cell-free particulate fraction of homogenates of castor bean seedlings with the active fungal endopolygalacturonase results in the production of a heat-stable, water-soluble component which is highly active as an elicitor of casbene synthetase activity.
