Primary stress responses in Arabidopsis thaliana exposed to gamma radiation.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

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

Exogenous salicylic acid-triggered changes in the glutathione transferases and peroxidases are key factors in the successful salt stress acclimation of Arabidopsis thaliana

Ingia / Ingia

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

[The enzymatic activity of the antioxidant system in the ontogeny of mutant norflurazone-tolerant Arabidopsis thaliana].

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The activities of superoxide dismutase and guaiacol-dependent peroxidase were studied in the ontogenesis of recessive homozygous mutants of Arabidopsis thaliana Heynh. le-2 and nfz24, which are characterized by two- to threefold increases in tolerance to the herbicide norflurazone. The mutants le-2

Effect of short-term salt stress on oxidative stress markers and antioxidant enzymes activity in tocopherol-deficient Arabidopsis thaliana plants.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Changes of carotenoids and anthocyanins content, lipid peroxidation, and activity of antioxidant enzymes were studied in wild type and tocopherol-deficient lines vte1 and vte4 of Arabidopsis thaliana subjected to 200 mM NaCI during 24 h. The salt stress enhanced the intensity of lipid peroxidation

Effect of VTE1 AND VTE4 gene inactivation on salt stress response in Arabidopsis thaliana.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The effect of inactivation of VTE1 and VTE4 genes, encoding enzymes involved in tocopherol biosynthesis, on concentrations of chlorophylls, carotenoids, anthocyanins and activity of catalase and guaiacol peroxidase in Arabidopsis thaliana under salt stress conditions were studied. It was shown, that

Effect of sodium nitroprusside and S-nitrosoglutathione on pigment content and antioxidant system of tocopherol-deficient plants of Arabidopsis thaliana.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Sodium nitroprusside (SNP) and S-nitrosoglutathione (GSNO) were used as a source of exogenous nitric oxide (NO) to investigate their effects on biochemical parameters and antioxidant enzyme response in leaves of wild type Columbia and tocopherol-deficient vte4 and vte1 mutant lines of Arabidopsis

Testing the optimal defense theory and the growth-differentiation balance hypothesis in Arabidopsis thaliana.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Two prominent theories proposed to explain patterns of chemical defense expression in plants are the optimal defense theory (ODT) and the growth-differentiation balance hypothesis (GDBH). The ODT predicts that plant parts with high fitness value will be highly defended, and the GDBH predicts that

Salicylic acid inhibits jasmonic acid-induced resistance of Arabidopsis thaliana to Spodoptera exigua.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The role of salicylic acid (SA) in plant responses to pathogens has been well documented, but its direct and indirect effects on plant responses to insects are not so well understood. We examined the effects of SA, alone and in combination with jasmonic acid (JA), on the performance of the

Genomic DNA structure of a gene encoding cytosolic ascorbate peroxidase from Arabidopsis thaliana.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

A genomic DNA clone encoding cytosolic ascorbate peroxidase was isolated from a genomic library of Arabidopsis thaliana, using a cDNA for the enzyme as a probe. Nucleotide sequence and primer extension analyses of this gene (APX1) revealed nine exons split by eight introns, one of which is inserted

Salinity effect on Cuscuta campestris Yunck. Parasitism on Arabidopsis thaliana L.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Stem holoparasitic flowering plants of the genus Cuscuta are globally distributed invasive species and agricultural pests. The present research represents the combined effect of salt stress (e.g. abiotic stress) and Cuscuta campestris infection (e.g. biotic stress) on the model host plant

[Salt Stress Response in Arabidopsis thaliana Plants with Defective Jasmonate Signaling].

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The effects of exogenous jasmonic acid (JA) on antioxidant enzymes in four-week-old leaves of wild-type Arabidopsis thaliana L. (Columbia-0) and jin1 (jasmonate insensitive 1) mutant plants with defective jasmonate signaling were investigated under normal conditions and under salt stress (200 mM

The activity of antioxidant enzymes in Arabidopsis thaliana exposed to colchicine and H2O2.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Studies on the possible interference of colchicine and H2O2 with the activity of some antioxidant enzymes were carried out on Arabidopsis thaliana v. Columbia grown in Murashige and Skooge nutrient medium. Measurements of superoxide dismutase (SOD), guaiacol peroxidase (POX), ascorbate peroxidase

Proteomic and physiological responses of Arabidopsis thaliana exposed to salinity stress and N-acyl-homoserine lactone.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

To evaluate the alleviating action of exogenous N-acyl-homoserine lactones (AHLs) on NaCl toxicity, morphological, physiological and proteomic changes were investigated in Arabidopsis thaliana seedlings. Salinity stress decreased growth parameters, increased malondialdehyde (MDA) contents and

Class III peroxidases are activated in proanthocyanidin-deficient Arabidopsis thaliana seeds.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

OBJECTIVE It has previously been shown that proanthocyanidins (PAs) in the seed coat of Arabidopsis thaliana have the ability to scavenge superoxide radicals (O2(-)). However, the physiological processess in PA-deficit seeds are not clear. It is hypothesized that there exist alternative ways in

Copper-induced oxidative stress and antioxidant defence in Arabidopsis thaliana.

Ingia / Ingia

Content of reactive oxygen species (ROS): O2*-, H2O2 and OH* as well as activities of antioxidant enzymes: superoxide dismutase (SOD), guaiacol peroxidase (POX) and catalase (CAT) were studied in leaves of Arabidopsis thaliana ecotype Columbia, treated with Cu excess (0, 5, 25, 30, 50, 75, 100, 150
