In recent years, metabolism researches using nanomaterials have been focusing on human and animal cells, and therefore very limited data are available about influence of nanomaterials on biosynthesis of secondary metabolites in plant cells. Plants produce different types of secondary metabolites including terpenoids, phenolics, tannins, and alkaloids, which are known to act as vital mediators f...

Fruits are one of the most important sources of polyphenols for humans, whether they are consumed fresh or as processed products. To improve the phenolic content of fruits, a novel field of interest is based on results obtained using elicitors, agrochemicals which were primarily designed to improve resistance to plant pathogens. Although elicitors do not kill pathogens, they trigger plant defen...

We have employed fluorescein and 125l-labeled elicitors of the defense response in soybeans to monitor the cellular distribution and movement of elicitors following their addition to a soybean cell suspension culture. Our results indicate that the macromolecular elicitors first bind to the cell surface and then internalize in a temperature- and energy-dependent endocytotic process. Within a few...

To defend themselves against invading pathogens plants utilize a complex regulatory network that coordinates extensive transcriptional and metabolic reprogramming. Although many of the key players of this immunity-associated network are known, the details of its topology and dynamics are still poorly understood. As an alternative to forward and reverse genetic studies, chemical genetics-related...

Objective: The present study aimed to determine the effect of two elicitors namely Methyl Jasmonate (MeJ) and Salicylic acid (SA) on adventitious root production of Psoralea corylifolia L. as the elicitors and at different concentrations. Methods: Adventitious roots of P. corylifolia L. were treated with different concentration of elicitors such as MeJ (10, 20, 30 and 40 μM/l) and SA (50, 100, ...

Plants use stomatal closure mediated by elicitors as the first step of the innate immune response to restrict the microbial entry. We present a comprehensive study of the effect of cryptogein and harpin, two elicitors from microbial pathogens of tobacco, on stomatal closure and guard cell signaling components in Arabidopsis thaliana, a model plant. Cryptogein as well as harpin induced stomatal ...

Induction of plant resistance against pathogens by defense elicitors constitutes an attractive strategy to reduce the use of fungicides in crop protection. However, all elicitors do not systematically confer protection against pathogens. Elicitor-induced resistance (IR) thus merits to be further characterized in order to understand what makes an elicitor efficient. In this study, the oligosacch...
