Drought-Stress-Induced Changes in Activities of Superoxide Dismutase, Catalase, and Peroxidase in Wheat Species

Relationship between water use efficiency (WUE) and production of different wheat genotypes at soil water deficit

“…The results of Gao et al [21] and Guo et al [22] by selecting winter wheat cultivars as materials proved this point. Forthly, we also found that the changing trend of WUE and production under our condition of three stress levels is tightly linked with the location of their cultivation, which reflects the change of corresponding alleles of different genotypes under the pressure of natural and artificial selection [37,77]. Moreover, this might be linked with evolution of wheat root systems.…”

“…Plants have evolved a wide range of defense systems to survive continuous assault by an arsenal of biotic attacks, constantly changing weather and other environmental conditions [35,41,42,45,55,56,61,63,69,73,75,77]. Unlocking the physiological and molecular basis for the plasticity of plant defending metabolism not only provides access to a largely untapped resource of genes and selection markers for breeding enhanced stress tolerance in crops but also ensures improved food security and agricultural sustainable development worldwide [5,8,10,19,32,44,48,52,62].…”

“…Living organisms can be viewed as reducing-oxidising (redox) systems in which catabolic, largely oxidative processes produce energy and anabolic, principally reductive processes assimilate it [5,35,61,75,77]. Aerobic organisms exploit the redox potential of oxygen while controlling oxidation, in particular, the plants in arid and semi-arid zones.…”

Alginate oligosaccharides enhanced Triticum aestivum L. tolerance to drought stress

“…Supernatant was crude extraction of POD. The POD activity was measured according to the method of Zhang and Kirkham [40]. POD activity was measured with guaiacol as the substrate.…”

Changes of some anti-oxidative physiological indices under soil water deficits among 10 wheat (Triticum aestivum L.) genotypes at tillering stage

“…Drought is a complex physical-chemical process, in which many biological macromolecules and small molecules are involved, such as nucleic acids (DNA, RNA, microRNA), proteins, carbohydrates, lipids, hormones, ions, free radicals, mineral elements [3,8,12,13,18,20,22,26,31,43,49,50,55,65]. In addition, drought is also related to salt stress, cold stress, high temperature stress, acid stress, alkaline stress, pathological reactions, senescence, growth, development, cell cycle, UV-B damage, wounding, embryogenesis, flowering, signal transduction and so on [16,17,[26][27][28]36,37,[44][45][46][47][52][53][54]62]. Therefore, drought is connected with almost all aspects of biology.…”
