Phosphatidylcholine, labeled by two fluorescent fatty acids, was fed to cultured plant cells (Petrosilenum crispum, L.; VBI-0, Nicotiana benthiana, L.) and fluorescent diacylglycerol (DAG) was the major metabolite. When a glycoprotein elicitor, derived from Phytophthora sojae, was applied to the parsley cells and the small protein cryptogein from Phytophthora cryptogea was applied to the tobacc...

Hypericum triquetrifolium Turra. (Hypericaceae) is one of the important medicinal plants. This herb used in Turkish folk medicine for its antidepressant, anthelmintic and antiseptic effects. extracts have an commercial value pharmaceutical industry. Therefore, studies to increase amount secondary metabolites it contains are becoming widespread. Elicitors biological non-biological factors that c...

Catharanthus roseus L. is a medicinal plant that produces numerous indole terpenoid alkaloids, including vincristine and vinblastine, which are used for cancer treatment. The effect of specified precursors (L-phenylalanine, L-tyrosine) elicitors (chitosan, methyl jasmonate) on C. hairy roots (CHR) growth has been examined in order to increase the content vinblastine. Our results showed CHR gene...

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 ...

Humanity’s migrations across, and subsequent modification of, the landscape have had innumerable effects on the many organisms in which we share this world. Mounting evidence suggests that the dual processes of humanmediated extirpation of native species and the introduction of nonnative species have resulted in significant changes in biological diversity at different spatial scales. Global spe...

Fruit losses and wastage are mainly due to postharvest diseases; their control is reduced with pesticides. The excessive use of synthetic fungicides has caused harmful effects on human health the environment, so it therefore necessary reduce use. development new innocuous strategies led compounds natural or biological origin capacity induce plant defense system, which improves fruit’s response ...

Early blight (EB), caused by the necrotrophic pathogen Alternaria solani, is one of most common and destructive diseases in tomato (Solanum lycopersicum L.). The use fungicides a prominent tactic used to control EB; however, their undesirable effects on environment human health, as well involvement development resistant strains, have driven researchers search for new alternatives. Plant defense...

The Oomycota include many economically significant microbial pathogens of crop species. Understanding the mechanisms by which oomycetes infect plants and identifying methods to provide durable resistance are major research goals. Over the last few years, many elicitors that trigger plant immunity have been identified, as well as host genes that mediate susceptibility to oomycete pathogens. The ...

A previously unidentified class of compounds has been isolated from the regurgitant of the grasshopper species Schistocerca americana. These compounds (named here "caeliferins") are composed of saturated and monounsaturated sulfated alpha-hydroxy fatty acids in which the omega-carbon is functionalized with either a sulfated hydroxyl or a carboxyl conjugated to glycine via an amide bond. The reg...

The effect of fungal elicitors and calcium-channel modulators on the anthocyanin production in callus cultures of Daucus carota was studied. It was found that the addition of fungal elicitors resulted in higher anthocyanin accumulation on the 3rd day of culture, but they resulted in lower levels of anthocyanin on the 21st day. Fungal elicitor treatment also affected growth of the cultures, as e...
