abstract- to investigate the effect of draught stress on water relations, stomatal density, chlorophyll content and yield of rapeseed, an experiment was done with four levels of drought stress including l1 (field capacity, fc), l2 (70% available water content, awc), l3 (50% awc), and l4 (30% awc), within three growth stages- including stem elongation (t1), onset of flowering (t2) and silique fo...

Triticum aestivum L. and Zea maize L. are both sensitive to salinity stress which is a major problem faced by farmers today. In the present study, the effect of chitosan, a biologic elicitor under salinity stress was examined on growth parameters and biochemical markers in maize and wheat s...

introduction dehydration is one of the limiting factors of crop production. it results from increasing the amount of water losses from leaf or inadequate water absorption rate or combination of both. zinc used in many enzymes of the plant tissues and have catalytic role in activation of some enzymes. zinc is involved in the synthesis and degradation of proteins and is an essential micronutrien...

objective(s):hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. in the present study, we evaluated the effect of ethanolic extract of ensete superbum seeds (esse) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats. materials and methods:glucose, hba1c, total protein, albumin, renal function mark...

trr14 is a novel protein important in trehalose (α-d-glucosyl-[1,1]-α-d-glucopyranoside) signaling in arabidopsis. in this research, we provided evidences to demonstrate that trr14 plays role in arabidopsis responses to salt and drought stress. the transgenic arabidopsis plants over-expressing trr14 under the control of camv 35s promoter were generated. transformed lines showed higher transcrip...

mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...

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...
