A new chloroplastic Cu/Zn-superoxide dismutase (SOD) isoenzyme was identified in Arabidopsis thaliana ecotype Cvi. Genetic analyses indicated that the new isoenzyme was encoded by a Cvi-specific allele of Csd2 that was named Csd2-2. Paraquat treatments of A. thaliana ecotypes Ler and Cvi resulted in

The redox state of glutathione and ascorbate as well as the activity of superoxide dismutase classes were determined in leaves of Arabidopsis thaliana grown for seven days in the nutrient solution containing 0, 5 and 50 microM Cd or Cu excess. A decrease in GSH/GSSG ratio was found in plants under

Over-expression of superoxide dismutase exhibits lignification of vascular structures in Arabidopsis thaliana.

The present study demonstrated that over-expression of copper-zinc superoxide dismutase (Cu/Zn-SOD), an important enzyme scavenging reactive oxygen species, improved vascular structures through lignification and imparted tolerance to salt stress (NaCl) in Arabidopsis thaliana (Arabidopsis; accession

We characterized the accumulation patterns of Arabidopsis thaliana proteins, two CuZnSODs, FeSOD, MnSOD, PR1, PR5, and GST1, in response to various pathogen-associated treatments. These treatments included inoculation with virulent and avirulent Pseudomonas syringae strains, spontaneous lesion

Superoxide dismutases (SODs) are involved in protecting plants against diverse biotic and abiotic stresses. In the present study, a novel Cu/Zn-SOD gene (JcCu/Zn-SOD) was cloned from Jatropha curcas L. Quantitative reverse transcription-polymerase chain reaction analysis revealed that JcCu/Zn-SOD is

This work aims at identifying the effects of ethylene on the response of Arabidopsis thaliana root system to cadmium chloride (CdCl2) stress. Two ethylene-insensitive mutants, ein2-5 and ein3-1eil1-1, were subjected to (25, 50, 75, and 100 μM) CdCl2 concentrations, from which 75 μM concentration

Functional analysis of a wheat group 3 late embryogenesis abundant protein (TdLEA3) in Arabidopsis thaliana under abiotic and biotic stresses

התחבר הרשם

Late embryogenesis abundant (LEA) proteins are highly hydrophilic and thermostable proteins that could be induced by abiotic stresses in plants. Previously, we have isolated a group 3 LEA gene TdLEA3 in wheat. The data show that TdLEA3 was largely disordered under fully hydrated conditions and was

As the environment is inevitably exposed to ionizing radiation from natural and anthropogenic sources, it is important to evaluate gamma radiation induced stress responses in plants. The objective of this research is therefore to investigate radiation effects in Arabidopsis thaliana on individual

Superoxide dismutases (SODs) protect against reactive oxygen species (ROS) by detoxifying superoxide. Three types of SOD are present in plants: FeSOD, CuSOD, and MnSOD. The Arabidopsis thaliana genome contains three FeSOD genes, in which two (FSD2, and FSD3) are targeted to chloroplast thylakoids.

Antioxidant response of Arabidopsis thaliana seedlings to oxidative stress induced by carbon ion beams irradiation.

Due to the fact that carbon ion beams irradiation as an important type of ionizing radiation can potentially cause oxidative stress in plants, it is significant to evaluate the antioxidant response of plants to carbon ion beams radiation. Therefore, the objective of this study is to investigate the

To evaluate the physiological importance of chloroplastic ascorbate peroxidase (CHLAPX) in the reactive oxygen species (ROS)-scavenging system of a euhalophyte, we cloned the CHLAPX of Suaeda salsa (SsCHLAPX) encoding stromal APX (sAPX) and thylakoid-bound APX. The stromal APX of S. salsa (Ss.sAPX)

Antioxidant isoenzymes function to eliminate free radicals and are localized to several different subcellular compartments within the plant cell. In Arabidopsis thaliana exposed to ozone (O3), we have monitored the accumulation of mRNAs encoding both cytosolic and chloroplastic antioxidant

Alkylphenol ethoxylates are widely used as detergents, emulsifiers, solubilizers, wetting agents and dispersants. Octylphenol (OP) ethoxylates, one of alkylphenol ethoxylates, represent 15-20% of the market, and their metabolic residues may be discharged to surface waters, sediments and soils as a

Salicylic acid (SA) applied exogenously is a potential priming agent during abiotic stress. In our experiments, the priming effect of SA was tested by exposing Arabidopsis thaliana (L.) Heynh. plants to 2-week-long 10-9-10-5 M SA pretreatments in a hydroponic medium, followed by 1 week of 100mM NaCl
