A Fungal Elicitor of the Resistance Response in Wheat
Abstract An elicitor of the lignification response in wheat leaves was isolated from the germ-tube walls of wheat stem rust. The active compound causes metabolic changes typically correlated with the resistance response, i.e. the formation of lignin or lignin-like polymers in affected epidermal and mesophyll cells and the increased ...

Phytophthora parasitica var. nicotianae produces a 34-kDa glycoprotein elicitor (CBEL) that is localized in the cell wall. A cDNA encoding the protein moiety of this elicitor was cloned and characterized.

Novel cellulose-binding-domain protein in Phytophthora is cell wall localized. [PDF]
Cellulose binding domains (CBD) in the carbohydrate binding module family 1 (CBM1) are structurally conserved regions generally linked to catalytic regions of cellulolytic enzymes.

Crh proteins catalyze crosslinking of chitin and glucan polymers in fungal cell walls. Here, Bi et al. show that a Crh protein from the phytopathogenic fungus Botrytis cinerea acts as a cytoplasmic effector and elicitor of plant defense, and plants ...

Lithium alters elicitor-induced H2O2 production in cultured plant cells
Lithium pollution may seriously influence the metabolic and signalling processes of plants. In the present paper, we investigate the effect of lithium chloride on fungal elicitor-triggered H2O2 generation in Rubia tinctorum L. cell cultures.

A Microbial Fermentation Mixture Primes for Resistance Against Powdery Mildew in Wheat
Since many fungal pathogens develop resistance to fungicides, novel and low-cost alternative methods to improve plant health and fitness need to be developed. An approach to improve productivity in crops is to stimulate the plant’s own defence mechanisms

Pinosylvin stilbenes are natural phenolic compounds found in the Pinaceae family and act as phytoalexins. Some pinosylvin stilbenes have strong nematicidal activity against pine wood nematodes (PWNs: Bursaphelenchus xylophilus).

The Enzymatic Activity of Fungal Xylanase Is Not Necessary for Its Elicitor Activity [PDF]
AbstractFungal xylanases fromTrichoderma spp. are potent elicitors of defense responses in various plants. To determine whether enzymatic activity is necessary for elicitor activity, we used site-directed mutagenesis to reduce the catalytic activity of xylanase II from Trichoderma reesei.

Fatty acids bind to the fungal elicitor cryptogein and compete with sterols [PDF]
Cryptogein is a proteinaceous elicitor of plant defense reactions which also exhibits sterol carrier properties. In this study, we report that this protein binds fatty acids. The stoichiometry of the fatty acid–cryptogein complex is 1:1. Linoleic acid and dehydroergosterol compete for the same site, but elicitin affinity is 27 times lower for fatty ...

Transcriptional activation of plant defense genes by fungal elicitor, wounding, and infection. [PDF]
Activation of plant defense genes was investigated by analysis of transcripts completed in vitro by isolated nuclei. Elicitor treatment of suspension-cultured bean (Phaseolus vulgaris L.) cells caused marked transient stimulation of transcription of genes encoding apoproteins of cell wall hydroxyproline-rich glycoproteins (HRGP) and the phenylpropanoid
