Effects of molybdenum on water utilization, antioxidative defense system and osmotic-adjustment ability in winter wheat (Triticum aestivum) under drought stress

Drought stress tolerance mediated by zinc-induced antioxidative defense and osmotic adjustment in cotton (Gossypium Hirsutum)

“…The supernatant was applied to measure the activities of superoxide dismutase (SOD; EC 1.15.1.1) and catalase (CAT; EC 1.11.1.6) according to the descriptions of Wu et al (2014). The frozen cotton leaves were homogenized by 5 mL 50 mM sodium phosphate (pH 5.5) containing 0.2 mM EDTA-Na 2 .…”

“…The frozen cotton leaves were homogenized by 5 mL 50 mM sodium phosphate (pH 5.5) containing 0.2 mM EDTA-Na 2 . The supernatant was applied to measure the activity of ascorbate peroxidase (APX; EC 1.11.1.11) according to the description of Wu et al (2014).…”

“…The ROS can result in cell damages and MAD accumulation that as an indicator of oxidative stress to evaluate the degree of drought stress (Wu et al 2014). However, plants suffering from drought stress during their growth and development have developed various mechanisms to adjust to drought stress.…”

“…The antioxidative defences were donated by the regulations of antioxidative enzymes activities and non-enzymatic antioxidants contents, which are responsible for scavenging ROS and overcoming the adverse effects of drought stress (Yordanov et al 2000;Jiang and Zhang 2002). Moreover, another mechanism is osmotic adjustment by regulating osmotic adjustment products contents to maintain cell membranes integrity and osmotic balance under drought stress (Wu et al 2014).…”

“…Additionally, it can cause a series of physiological and biochemical changes in plants (Wu et al 2014;Li et al 2015;Zhang 2015). To cope with the challenging aspects of drought, plants use several mechanisms and produce response at physiological and molecular levels (Shiriga et al 2014).…”
