chilling is an important environmental stress that influences the yield and quality of many agricultural crops. different plants use different systems to endure this stress and minimize its effects. one of these systems is enzymatic reaction. to find out more about responses of different grapevine species and cultivars to the low temperature conditions, their enzymatic changes were evaluated in...

Objective(s):Small ubiquitin-like modifiers (SUMOs) are a family of ubiquitin-related, proteins that are involved in a wide variety of signaling pathways. SUMOylation, as a vital post translational modification, regulate protein function in manycellular processes. Diazinon (DZN), an organophosphate insecticide, causses oxidative stress and subsequently programmed cell death in different tissues...

Salt stress severely limits soybean production worldwide. Calcineurin B-like protein-interacting protein kinases (CIPKs) play a pivotal role in plant’s adaption to salt stress. However, their biological roles remain poorly understood. Here, the GmCIPK2 expression was increased by NaCl and hydrogen peroxide (H2O2). GmCIPK2-overexpression Arabidopsis hairy roots displayed improved tolerance, wher...

Background: Camel and sheep have high disperse and tolerance in tropical regions. But different results of harsh condition tolerance ability of them have been reported. ObjectiveS: The objective of this study was to determine the heat stress tolerance in camel and sheep by evaluating changes in blood serum metabolites and to report and compare the serum biochemical profile of sheep and camel du...

diazinon is an organophosphate which is extensively used in trade and agriculture. due to its widespread application, its toxicity is common. several studies have shown that organophosphates are able to induce oxidative stress by generating free radicals and depletion of endogenous antioxidants. pomegranate seed oil (pso) possesses anti-inflammatory and antioxidant effects. in this study, the e...

background: sigma factors are proteins that regulate transcription in bacteria. sigma factors can be activated in response to different environmental conditions. the rpos (rna polymerase, sigma s) gene encodes sigma-38 (σ38, or rpos), a 37.8 kda protein in pseudomonas aeruginosa (p. aeruginosa) strains. rpos is a central regulator of the general stress response and operates in both retroactive ...

stress is a threatening factor that all living organisms encounter throughout life. depending on the type of stress, there are several mechanisms for keeping body homeostasis to minimize stress effects. brain is an organ which shows high sensitivity to stress conditions. although many studies have shown induced-stress effects on rat embryos, little is known about the mechanisms involved in copi...
