The oxidative burst has been suggested to be a primary event responsible for triggering the cascade of defense responses in various plant species against infection with avirulent pathogens or pathogen-derived elicitors. The molecular mechanisms of rapid production of active oxygen species (AOS), however, are not well known. We isolated homologs of gp91 phox, a plasma membrane protein of the neu...

Abstract This study confirmed the association with inflammation-related proteins, mediators, and cytokines using saucerneol D from Saururus chinensis leaf, a useful ingredient increased through elicitor treatment. To confirm anti-inflammatory effect, were treated lipopolysaccharide, which induces pro-inflammatory factors in Raw 264.7 cell. The influences measured by dint of chemical assay weste...

Induction of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is essential for the biosynthesis of sesquiterpenoid phytoalexins and steroid derivatives in Solanaceous plants following stresses imposed by wounding and pathogen infection. To better understand this complex step in stress-responsive isoprenoid synthesis, we isolated three classes of cDNAS encoding HMGR (hmg1, hmg2, and hmg3) ...

Molecular oxygen is essential for the existence of life of aerobic organisms including plants. However, Reactive Oxygen Species (ROS), which include the superoxide anion (O2•-), hydroxyl radical (•OH), perhydroxyl radical (•O2H) and hydrogen peroxide (H2O2), are generated in all aerobic cells as byproducts of normal metabolic processes. In general, under various conditions of environmental stre...

BACKGROUND Elicitation, which is a way of inducing plant secondary metabolism, may be an effective method for improving the quality of plant food. The aim of this study was to determine how the application of jasmonic acid (as an abiotic elicitor) and yeast extract (as a biotic elicitor) influences the production of some bioactive compounds in marjoram and the antioxidant activity of this herb....
