“…In order to verify the morpho-physiological and biochemical changes, molecular markers were used in this study to analyze and confirm the variation among the treatments. It has been discussed in various sources that ROS caused by salinity stress can severely destroy cellular components such as lipids, proteins and DNA [57,58]. Under salinity stress, all the main components of DNA (i.e., purine and pyrimidine bases, sugars and phosphodiester bonds), could suffer from damage [59].…”

In this study, the positive role of hydrogen peroxide (H2O2) pretreatment in mitigating the adverse impacts of seawater stress has been evaluated in two wheat (Triticum aestivum L.) cultivars, namely Gemmiza 11 as a salt-sensitive and Misr 1 as a salt-tolerant cultivar, with contrasting phenotypes in response to the salinity stress. Under normal conditions, wheat seeds eustress with H2O2 have shown significant effects on the improvement of plant growth parameters, such as dry weight and root and shoot lengths. Under salt stress conditions, seeds eustress with H2O2 have shown a reduction in damage to plant growth and physiological parameters as compared to the seeds kept as un-primed in both wheat cultivars. In addition, eustress of seeds with H2O2 has induced an increment in the pigments content, proline level and mineral uptake (K+, Ca2+ and Mg2+). Moreover, seeds eustress with H2O2 have shown significant decrement in Na+ content uptake in plants and that subsequently reduced lipid peroxidation. Seawater stress has increased the activity of the antioxidant system based on catalase (CAT), peroxidase (POD) and ascorbate peroxidase (APX) in both cultivars, except POD in Gemmiza 11. Similarly, the application of H2O2 has further enhanced the activity of the antioxidant system in stressed plants and this enhancement of the antioxidant system further reduced Na+ content in plants and subsequently increased the growth parameters. Results of inter-simple sequence repeat (ISSR) markers have shown clear differentiation among the treatments and have provided strong evidence in support of the hypothesis proposed in this study that H2O2 eustress improves seed tolerance and enhances plant growth parameters under seawater stress.

“…Previous studies have shown that the maintenance of a low Na + : K + ratio provides favourable conditions for continued physiological and metabolic activity (Yu et al 2012). Transgenic rice plants expressing SfIAP exhibited a significantly lower Na + : K + ratio in comparison to the WT and VC plants during salt stress.…”

Abstract. Programmed cell death-associated genes, especially antiapoptosis-related genes have been reported to confer tolerance to a wide range of biotic and abiotic stresses in dicotyledonous plants such as tobacco (Nicotiana tabacum L.) and tomato (Solanum lycopersicum L.). This is the first time the antiapoptotic gene SfIAP was transformed into a monocotyledonous representative: rice (Oryza sativa L.). Transgenic rice strains expressing SfIAP were generated by the Agrobacterium-mediated transformation method and rice embryogenic calli, and assessed for their ability to confer tolerance to salt stress at both the seedling and reproductive stages using a combination of molecular, agronomical, physiological and biochemical techniques. The results show that plants expressing SfIAP have higher salt tolerance levels in comparison to the wild-type and vector controls. By preventing cell death at the onset of salt stress and maintaining the cell membrane's integrity, SfIAP transgenic rice plants can retain plant water status, ion homeostasis, photosynthetic efficiency and growth to combat salinity successfully.

“…In plants soil salinity causes both osmotic stress and ionic toxicity, which can be lethal under prolonged exposure ( Zhu 2001 ; Munns and Tester 2008 ; Yu et al 2012 ). Halophytes survive salinity by sequestering salts in vacuoles and accumulating organic osmolytes in their cytoplasm ( Flowers and Colmer 2008 ; Hameed and Khan 2011 ; Nedjimi 2014 ), thus reducing ion toxicity while maintaining osmo-balance.…”

Effects of salinity and ascorbic acid on growth, water status and antioxidant system in a perennial halophyte

Limonium stocksii is a potential commercial cut-flower crop for saline areas using brackish water. We therefore were interested to learn about the mechanism of its salinity tolerance. Plants grew well under lower saline conditions (300 mM NaCl) but higher salinities reduced growth. An increase in leaf osmolality and the management of salinity-induced oxidative stress are the key strategies employed. Exogenous AsA application improved the functioning of the AsA-dependent antioxidant system, leading to better growth.
