Ascorbate peroxidase (APX) acts indispensably in synthesizing L-ascorbate (AsA) which is pivotal to plant stress tolerance by detoxifying reactive oxygen species (ROS). Enhanced activity of APX has been shown to be a key step for genetic engineering of improving plant tolerance. However it needs a deeper understanding on the maintenance of cellular ROS homeostasis in response to stress. In this...

Soybean (Glycine max L.) is the most important crop plant in world. Soil saline-alkali seriously inhibits soybean yield and quality. This study aims to investigate impact of graphene oxide (GO) Rhizobium (Rh) on expression soybean-related genes as well growth under stress. The results show that GO + Rh-treated increased number root nodules by 5.43 times compared with control (Ctrl), total nitro...

The effect of Thiourea, Galmet and Thiogalmet on the antioxidant protection capacity plants in moderate drought conditions was studied. is a new chemical composition that contains Thiourea (Tu) - preparation consists mixture potassium, ammonium, magnesium gallates, potassium molybdate ammonium paramolybdate. Biological tests were performed vegetation complex Institute Genetics, Physiology Plant...

Ascorbate peroxidases (APX) are class I heme-containing enzymes that convert hydrogen peroxide into water molecules. The gene encoding APX has been characterized in 11 strains of Trypanosoma cruzi that are sensitive or resistant to benznidazole (BZ). Bioinformatic analysis revealed the presence of two complete copies of the T. cruzi APX (TcAPX) gene in the genome of the parasite, while karyotyp...

Recently, the use of nanofertilizers has received a great deal attention in managing plants under biotic and abiotic stresses. However, studies that elucidate role silicon dioxide nanoparticles (SiO2NPs) regulating maize tolerance to drought stress are still at early stages development. In this study, were treated with SiO2NPs (0.25 g/L as foliar spray) displayed considerable improvement growth...

many studies have proved that the dietary micronutrient has an inhibitory effect against experimentally induced rat hepatocarcinogenesis. the present work is an attempt to understand combined effect of selenium (se) and vitamin d3 (vit d3) on some potential protein expression markers of carcinogenesis, such as metallothionein (mt), p53 and antioxidant levels during diethyl nitrosamine (den) ind...

background: the mechanism of cadmium induced osteoporosis is not well understood, so in this study, we examined the toxicity of bone marrow mesenchymal stem cell (mscs) following treatment of rats with cdcl2 in drinking water, to revile the effect of this chemical on differentiation potential of mscs. methods: at the end of third passage, mscs were grown in the osteogenic medium for 21 days. to...

strenuous aerobic exercise is associated with oxidative stress and tissue damage. therefore, we have investigated the effects of exercise and eicosapentaenoic acid supplementation, with or without vitamin e, on the plasma levels of vitamin c, e and a, il-6, and glutathione peroxidase activity in basketball players. thirty four male basketball players, enrolled in the study. subjects received 2g...
