Cells must respond to an array of environmental and developmental cues. The signaling networks that have evolved to generate appropriate cellular responses are varied and are normally composed of elements that include a sequence of receptors, nonprotein messengers, enzymes and transcription factors. Receptors are normally highly specific for the physiological stimulus, and therefore are dispara...
An alfalfa-based protein hydrolysate (EM) has been tested in tomato (Solanum lycopersicon L.) plants at two different concentrations (0.1 and 1 mL L-1) to get insight on its efficacy as biostimulant in this species and to unravel possible metabolic targets and molecular mechanisms that may shed light on its mode of action. EM was efficient in promoting the fresh biomass and content in chlorophy...
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...
Synthetic elicitors are drug-like compounds that are structurally distinct from natural defense elicitors. They can protect plants from diseases by activating host immune responses and can serve as tools for the dissection of the plant immune system as well as leads for the development of environmentally-safe pesticide alternatives. By high-throughput screening, we previously identified 114 syn...
Plant secondary metabolites (SMs) play important roles in plant survival and creating ecological connections between other species. In addition to providing a variety of valuable natural products, help protect plants against pathogenic attacks environmental stresses. Given their sessile nature, must themselves from such situations through accumulation these bioactive compounds. Indeed, act as h...
The effectiveness of three kinds of enzymes (chitinase, β-glucuronidase, and lysing enzyme complex), employed as elicitors to enhance the β-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), was examined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutions at three different levels on the...
Macro and micro-elements, carbon sources and elicitors play a central role during Panax ginseng hairy root growth, biomass and ginsenoside production and also influence numerous root developmental stages in largescale bioreactor culture. Due to the lack of biosynthetic nutrients and signalling-inducing nutrients, the regulatory role of mineral elements is not well understood. We have geneticall...
Plant Flavonoids are considered as naturally occurring bioactive compounds. In the present study, chitosan and Aspergillus niger elicitors were used as chemical and fungal elicitors, respectively. The cell suspension culture of Andrographis paniculata (Burm. f.) Nees was established in 50 ml MS media supplemented with 2,4-D: BAP (1.0:0.5 mg/l) and treated with chitosan and Aspergillus niger eli...
