Phenolic compounds belong to a class of secondary metabolites and are implicated in a wide range of responsive mechanisms in plants triggered by both biotic and abiotic elicitors. In this study, we approached the combinational effects of ethylene and MeJA (methyl jasmonate) on phenolic compounds profiles and gene expressions in the medicinal plant Catharanthus roseus. In virtue of a widely non-...
Spatiotemporal changes in cellular calcium (Ca2+) concentrations are essential for signal transduction in a wide range of plant cellular processes. In legumes, nuclear and perinuclear-localized Ca2+ oscillations have emerged as key signatures preceding downstream symbiotic signaling responses. Förster resonance energy transfer (FRET) yellow-based Ca2+ cameleon probes have been successfully expl...
Plants can perceive a wide range of biotic attackers and respond with targeted induced defenses. Specificity in plant non-self-recognition occurs either directly by perception of pest-derived elicitors or indirectly through resistance protein recognition of host targets that are inappropriately proteolyzed. Indirect plant perception can occur during interactions with pathogens, yet evidence for...
The (-)-hyoscyamine, atropine and scopolamine (hyoscine) are three valuable tropane alkaloids while scopolamine is the most important member of this group for the pharmaceutical industry due to its higher demand compared to hyoscyamine and atropine. Scopolamine is an anticholinergic reagent with several therapeutic applications. In the current study, the hairy roots culture of Daturametel was u...
Resveratrol is the most important stilbene phytoalexin synthesized naturally or induced in plants, as a part of their defense mechanism. Grapes and their derivative products, including juice and wine, are the most important natural sources of resveratrol, consisting of notably higher amounts than other natural sources like peanuts. Consumption of red wine with its presence of resveratrol explai...
In the Solanaceae, biotic and abiotic elicitors induce de novo synthesis of sesquiterpenoid stress metabolites known as phytoalexins. Because plant hormones play critical roles in the induction of defense-responsive genes, we have explored the effect of abscisic acid (ABA) on the synthesis of capsidiol, the major wild tobacco (Nicotiana plumbaginifolia) sesquiterpenoid phytoalexin, using wild-t...
Herbivore attack elicits changes in cytokinins (CKs), but how these changes influence defense signaling remains poorly described. We investigated the influence of the CK pathway on the well-described inducible defense pathways of Nicotiana attenuata in response to wounding with and without elicitors from the specialist herbivore Manduca sexta. CK pathway manipulation often suffers from substant...
Glaucium flavum Crantz is a medicinal plant species which contains high variety of isoquinoline alkaloids, the main alkaloid glaucine, possessing antitussive activity. In vitro cultivation was investigated as an alternative and sustainable approach for this characterized by decreasing distribution. The biotechnological production secondary metabolites could be improved addition elicitors such j...
Plant subtilases (SBTs) or subtilisin-like proteases comprise a very diverse family of serine peptidases that participates in broad spectrum biological functions. Despite increasing evidence for roles SBTs plant immunity recent years, little is known about wheat (Triticum aestivum) (TaSBTs). Here, we identified 255 TaSBT genes from bread using the latest version 2.0 reference genome sequence. T...
Biotic stress factors are one of the major constraints plants face, and they significantly affect production yield. There multiple ways to cope with factors, including genetic enhancement. When cannot provide sufficient protection, pesticides commonly applied. Plant defense elicitors a new approach for boosting plants' natural immune responses tolerance levels. The newly identified promising pl...
