The early stages of quinoa germination are sensitive to drought stress. For this purpose, a study entitled the effect selenium in different concentrations on characteristics and some antioxidant enzymes under stress conditions with polyethylene glycol (PEG 6000) was investigated. first experimental factor seed priming (from two sources: sodium selenate nanoparticles: SeNPs ? 33.4 nm) at 0.5, 1....

As an important gaseous regulator, hydrogen sulfide (H2S) is involved in various aspects of plant processes, including seed germination, stomatal movement, and postharvest senescence. The preservation capacity Lanzhou lily (Lilium davidii var. unicolor Salisb) scales fumigated with or without exogenously applied sodium hydrosulfide (NaHS, a H2S donor) was investigated the current study. Results...

Euglena gracilis lacks a catalase and contains a single APX (ascorbate peroxidase) and enzymes related to the redox cycle of ascorbate in the cytosol. In the present study, a full-length cDNA clone encoding the Euglena APX was isolated and found to contain an open reading frame encoding a protein of 649 amino acids with a calculated molecular mass of 70.5 kDa. Interestingly, the enzyme consiste...

a hydroponic experiment was conducted to investigate the effect of of magnesium (mg) deficiency on plant cell metabolism in pgs durum wheat cultivar. the experiment was conducted in 4 replications as a completely randomized design in 2010. result showed that magnesium deficiency increased reactive oxygen species (ros) production such as hydrogen peroxide (h2o2). furthermore, mg deficiency decli...

Abstract During postharvest life, strawberry fruit as a perishable commodity exhibiting short shelf life suffers from fungal decay that severely limits its marketability and nutritional value. Herein, we investigated the mechanisms activated by exogenous phytosulfokine ? (PSK?) application at 150 nM to delay senescence relieve in during storage 4 °C for 18 days. Our results showed higher extrac...

Microbial assisted phytoremediation and reclamation are both potential contaminated soil remediation technologies, but little is known about the combined application of two technologies on real soils. This study investigated Herbaspirillum sp. p5-19 (p5-19) with alien improvement improving stress tolerance enhancing accumulation Mn, Cu, Zn, Cd by Vetiveria zizanioides L. in copper tailings. Phy...

kentucky bluegrass (poa pratensis l.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. the objective of this study was to investigate whether prohexadione-calcium (pro-ca) may play a role in promoting ...

Materials and methods: Classical biochemical methods were used to determine plasma malondialdehyde (MDA), nitric oxide (NO), glutathione peroxidase (GSH-Px), catalase (CAT), superoxide dismutase (SOD), and glutathione (GSH) levels. Enzyme-linked immunosorbent assay was used to determine plasma insulin levels and reverse transcriptasepolymerase chain reaction was used to determine the levels of ...

Although brassinosteroids (BRs) play crucial roles in plant development and stress tolerance, the mechanisms by which they have these effects are poorly understood. Here, we investigated the possible mechanism of exogenously applied BRs on reactive oxygen species (ROS), antioxidant defence and methylglyoxal (MG) detoxification systems in Ficus concinna seedlings grown under high-temperature (HT...
