A soluble elicitor of glyceollin accumulation was released from insoluble mycelial walls of Phytophthora megasperma var. sojae after incubation with soybean cotyledon tissue for as little as 2 minutes. Various enzymic and chemical treatments of the released elicitor indicated that the activity resided in a carbohydrate moiety, and gel filtration disclosed the presence of at least two active mol...

Elicitor-active preparations from the fungal pathogen of bean Colletotrichum lindemuthianum stimulated the accumulation of products characteristic of lipid peroxidation in treated bean tissues. Bean suspension cells treated with crude and purified elicitors accumulated ;lipofuscin-like pigment' (LEP) and malondialdehyde. The accumulation of LFP after about 6 h of treatment coincided with the on...

For many years, research on a suite of plant defense responses that begin when plants are exposed to general microbial elicitors was underappreciated, for a good reason: There has been no critical experimental demonstration of their importance in mediating plant resistance during pathogen infection. Today, these microbial elicitors are named pathogen- or microbe-associated molecular patterns (P...

Hairy roots were induced by infecting stems and leaves of Glycyrrhiza inflata with Agrobacterium rhizogenes ATCC 15834. The optimization of growth and glycyrrhizin accumulation of G. inflata hairy roots was studied. Sucrose (6%, w/v) was optimal for growth and glycyrrhizin accumulation in G. inflata hairy roots. Effects of elicitors like chitosan, methyl jasmonate, and yeast extract on glycyrrh...

Endopolygalacturonic acid lyase, purified from the phytopathogenic bacterium, Erwinia carotovora , induces phytoalexin accumulation in soybean ( Glycine max L .) cotyledons. This pectin-degrading enzyme releases heat-stable elicitors of phytoalexin accumulation from soybean cell walls, citrus pectin, and citrus sodium polypectate. The most elicitor-active m olecules ob­ tained by treating soybe...

the aim of this review was to represent a category of applied plant biostimulants and to highlight the effect of their application on morphological and phytochemical properties of medicinal plants in in vivo and in vitro conditions and their mechanism of action. plant biostimulants, safe for both human beings and the environment, are substances or materials, except for nutrients and pesticides,...

in this study the effect of different concentrations of some abiotic elicitors (salicylic acid, jasmonic acid, cadmium chloride and sodium chloride) with different incubation times (3, 6, 9 and 12) on azadiractin production and cell growth in the cell culture of the iranian native neem were investigated. cell growth rate was measured by changes in dry cell weight and it was used as a basis for ...

Polysaccharides in wine play important roles the stabilization and sensory properties of wines. Elicitor application constitutes an interesting field research since it is indirectly involved accumulation grape cell walls molecules like callose, lignin, phenolic compounds glycoproteins. Currently, biomimetic calcium phosphate (ACP) nanoparticles are successfully used viticulture for controlled d...
