Salt stress is one of the most serious factors limiting the productivity of rice, the staple diet in many countries. Gibberellic acid has been reported to reduce NaCl-induced growth inhibition in some plants including rice. Most paddy soils have a natural population of Cyanobacteria, prokaryotic photosynthethic microorganisms, which synthesize and liberate plant growth regulators such as gibber...

this study investigated the variation between two sugar beet (beta vulgaris l.) cultivars with respect to growth parameters and photosynthetic rates of individual attached leaves during salinization. sugar beet plants grown in sand culture were gradually exposed to different levels of salinity (0, 50, 150 , 250, and 350 mm, nacl+cacl2 in 5:1 ratio). salt concentrations significantly decreased a...

ornithine is a non-proteinogenic amino acid, which plays an essential role in the metabolism of plants. regard to the chirality of the molecule, physiological response of the plant cells to its two enantiomers have not been widely investigated yet. in the present study, suspension-cultured tobacco cells were treated with 1 mm of d- and lenantiomers of ornithine in normal conditions as well as u...

Hypertensive cardiovascular damage is accelerated by salt loading but counteracted by dietary potassium supplementation. We suggested recently that antioxidant actions of potassium contribute to protection against salt-induced cardiac dysfunction. Therefore, we examined whether potassium supplementation ameliorated cuff-induced vascular injury in salt-sensitive hypertension via suppression of o...

Plants have evolved several strategies, including regulation of genes through epigenetic modifications, to cope with environmental stresses. DNA methylation is dynamically regulated through the methylation and demethylation of cytosine in response to environmental perturbations. High-affinity potassium transporters (HKTs) have accounted for the homeostasis of sodium and potassium ions in plants...

background: there is paucity of information on the prevalence of hypertension and its risk factors among bank employees at global level. objective: to assess the prevalence and risk factors of hypertension among bank employees in puducherry, india. methods: a cross-sectional study was conducted on 192 (128 male and 64 female) bank employees from 12 nationalized banks in urban puducherry, india....

understanding of physiological responses of salt tolerance might be lead to identify main salt tolerance mechanisms and essential approaches for improving grain yield stability, and also to select salt tolerant wheat cultivars. thus, the effects of salinity were investigated on grain yield and some of the characteristics related to salt tolerance. six wheat cultivars (roshan, kavir, karchia, ga...

this study investigated the influence of inoculation with an arbuscular mycorrhizal fungus (amf), glomus mosseae (nicol & gerd.) on growth and antioxidant enzyme activities (sod, cat, gupx) in shoots and roots of wheat (triticum aestivum l.) affected by three different levels of salt stress. the experiment was arranged as a factorial in randomized complete block design (rcbd) with three replicat...

Transgenic plants tolerant to various environmental stresses are being developed to ensure a consistent food supply. We used a transgenic rice cultivar with high saline tolerance by introducing an RNA-binding protein (RBP) from the ice plant (Mesembryanthemum crystallinum); differences in salt-soluble protein expression between nontransgenic (NT) and RBP rice seeds were analyzed by 2D differenc...
