Effects of juglone and lawsone on oxidative stress in maize coleoptile cells treated with IAA
Naphthoquinones are secondary metabolites widely distributed in nature and produced by bacteria, fungi and higher plants. Their biological activity may result from induction of oxidative stress, caused by redox cycling or direct interaction with cellular macromolecules, in which quinones act as electrophiles. The redox homeostasis is known as one of factors involved in auxin-mediated plant grow...
متن کاملzinc(II) with lawsone, juglone and naphthazarin
The complexation equi li bria of zinc(lI ) wi th 2-hydroxy-IAnaphthoquinone. 5-hydroxyIA-naphthoquinone and 5.8-dihydroxyIA-naphthoquinone have been studied spectrophotometri call y as a function of pH in 50~ (1'/1') ethanol-water medium at 25°C and an ionic strength of 0.1 M NaCI04 . The spectral study of the complexati on reactions has been carried out in solutions contain ing equimolar conce...
متن کاملA comparison of the effects of IAA and 4-Cl-IAA on growth, proton secretion and membrane potential in maize coleoptile segments.
The physiological activity of exogenous 4-Cl-IAA, as compared to IAA, was examined in maize coleoptile segments. It was found that in this model system 4-Cl-IAA is much more active in the stimulation of elongation than IAA. Simultaneous measurements of growth and external pH indicated that administration of either IAA or 4-Cl-IAA resulted in medium acidification. The kinetics of the pH changes,...
متن کاملExpression Patterns of Glutathione Transferase Gene (GstI) in Maize Seedlings Under Juglone-Induced Oxidative Stress
Juglone (5-hydroxy-1,4-naphthoquinone) has been identified in organs of many plant species within Juglandaceae family. This secondary metabolite is considered as a highly bioactive substance that functions as direct oxidant stimulating the production of reactive oxygen species (ROS) in acceptor plants. Glutathione transferases (GSTs, E.C.2.5.1.18) represent an important group of cytoprotective ...
متن کاملEstablishment of Oxidative Stress Modeling during Spermatogonial Stem Cells Cultivation Treated with Different Doses of H2O2
Introduction: Nowadays, spermatogonial stem cells (SSCs) cultivation has been used by many researchers as an effective tool for infertility treatments. Oxidative conditions can be effective on cell proliferation and differentiation of these cells. So, the aim of this study was to establish oxidative stress model for antioxidant activity of some drugs investigation during SSCs in vitro culture. ...
