“…Growth hormones enhance the resilience of plants to stress; they are key components for proper growth and maintenance under stressful conditions (Asgher et al 2015). The positive influence of growth hormones such as JA (Sirhindi et al 2016) and NO (Bai et al 2015;Ahmad, Abdel Latef, et al 2016) has been reported earlier as well. In the present study, application of JA and NO to NaClstressed S. lycopersicum enhanced growth and subsequent biomass accumulation, thereby depicting their active involvement in cell division and organ differentiation.…”

We investigated the effects of exogenous application of jasmonic acid (JA) and nitric oxide (NO) on growth, antioxidant metabolism, physio-biochemical attributes and metabolite accumulation, in tomato (Solanum lycopersicum L.) plants exposed to salt stress. Treating the plants with NaCl (200 mM) resulted in considerable growth inhibition in terms of biomass, relative water content, and chlorophyll content, all of which were significantly improved upon application of JA and NO under both normal and NaCl-stress treatments. Salt treatment particularly 200 mM NaCl caused an apparent increase in electrolyte leakage, lipid peroxidation, and hydrogen peroxide production, which were reduced by exogenous application of JA and NO. Salt treatment triggered the induction of antioxidant system by enhancing the activities of antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR). Application of JA and NO separately as well as in combination caused a significant improvement in activities of SOD, CAT, APX, and GR activities. JA and NO either applied individually or in combination boosted the flavonoid, proline and glycine betaine synthesis under NaCl treatments. In conclusion, the exogenous application of JA and NO protected tomato plants from NaCl-induced damage by up-regulating the antioxidant metabolism, osmolyte synthesis, and metabolite accumulation.

“…Free proline content was determined as described by Bates et al (1973) with slight modification Proline amount was determined using the methods of Bates et al (1973) and Bai et al (2015). After extraction with 3 % (m/v) 5-sulfosalicylic acid at room temperature, proline content was determined from a standard curve and calculated on a fresh mass basis.…”

“…They can function in osmotic adjustment, or act as signalling molecules to activate some specific transduction pathways (Misra et al 2009). Secondary stresses such as oxidative damage often occur (Mittler et al 2002, Xu et al 2015 as a consequence of excess production of ROS. To counteract the oxidative stress, both enzymatic and non-enzymatic antioxidants have evolved in plants (Zheng et al 2009a, Lin et al 2012.…”

A hydroponic culture was conducted to evaluate the effects of KCl and sodium nitroprusside (SNP; a nitric oxide donor) in wheat seedlings under salt stress. Exposure to 100 mM NaCl for 7 d decreased biomass of wheat seedlings, root activity and H + -ATPase activity, significantly increased free proline content, reactive oxygen species (ROS) accumulation and lipid peroxidation, and suppressed the activity of superoxide dismutase (SOD). Moreover, NaCl stress significantly decreased the K + and increased the Na + content. Addition of KCl or SNP led to the increase in root activity and soluble protein content, stimulated the activity of SOD, and decreased free proline content, superoxide anion radical generation rate, and lipid peroxidation. The increased K + and decreased Na + content in the leaves of treated seedlings indicated that suitable KCl and NO addition stimulated the selective transport of K + and Na + to the maintain K + /Na + homeostasis.

“…Plants carry a defence mechanism to counter HM stresses, which increase antioxidant enzyme activities such as catalase (CAT, EC 1.11.1.6) or per oxidases (POD, EC 1.11.1.7) [18]. However, the reaction of plants to HMs is generally under the environmental influence of plant genotype [4].…”

Nowadays, the contaminations generated by anthropogenic activities have had damaging effects on the life cycle of plants, particularly on the plants living in the vicinity of urban areas that are more associated with the life of people. Bamboo, as a local plant, is one of the most widely used plants in China. So, a pot experiment was conducted to investigate the effects of three HMs (Cu, Pb, and Zn) in four different concentrations (0 (for control), 500 mg/kg, 1000 mg/kg, and 200 mg/kg), with complete randomized design (CRD) by five replications for each treatment to measure the antioxidant enzymes, lipid per oxidation (LP), soluble protein (SP), gas exchange parameters, and morphological indexes in Sasa kongosanensis f. aureostriatus. The results indicated that the antioxidant responses had an arc-shaped trend with various alterations in which POD and CAT first increase with low concentration of HMs (500 mg/kg) and then decrease with the increase of heavy metal (1000 mg/kg and 2000 mg/kg). Additionally, measuring of MDA content and soluble protein illustrated that MDA content and soluble protein increase with excess of HMs in different levels, and also the excess of HMs significantly decreases the photosynthesis properties. Moreover, the results obtained by morphological indices showed that low concentration of HMs increases both percentage of shoot length and percentage of emerge plants at all three kinds of HMs, but observe a downward trend with excess of heavy metal in 1000 mg/kg and 2000 mg/kg. Overall, in "Sasa kongosanensis f. aureo -striatus, results indicated that low concentration of HMs (500 mg/kg) can help the plant growth, while excess of HMs (1000-2000 mg/kg) alleviates the plant growth. On the other hand, Pb revealed the lowest antioxidant
