“…The present results indicate that salinity stress increased the H 2 O 2 content of pepper plants (Fig. C), thereby inducing a high level of ROS (Liu et al ). Over‐generation of ROS can inhibit electron transport by causing degradation of proteins and influencing the repair process of PSII (Allakhverdiev et al ).…”

“…This detrimentally affects metabolic activities in the cytosol including protein metabolism, CO 2 assimilation, N assimilation and lipid metabolism (Woo et al , Chen et al , Allakhverdiev et al , Ahmad , Pandolfi et al , Ahmad et al ). Salinity stress has also been linked to accumulation of reactive oxygen species (ROS) (Mittler , Liu et al ). Although ROS are obviously required for metabolic activities in the cell as secondary messengers (Choudhury et al ), overproduction can damage cellular membranes through oxidation of key organic molecules such as proteins, nucleic acids and lipids (Sharma et al , Bose et al , Shi et al ).…”

There seems to be no report in the literature on the effect of melatonin (MT) in relieving the detrimental effects of combined application of salt stress (SS) and iron deficiency (ID). Therefore, the effect of MT on the accumulation/synthesis of endogenous nitric oxide (NO) and hydrogen sulphide (H2S) and how far these molecules are involved in MT‐improved tolerance to the combined application of ID and SS in pepper (Capsicum annuum L) were tested. Hence, two individual trials were set up. The treatments in the first experiment comprised: Control, ID (0.1 mM FeSO4), SS (100 mM NaCl) and ID + SS. The detrimental effects of combined stresses were more prominent than those by either of the single stress, with respect to growth, oxidative stress and antioxidant defense attributes. Single stress or both in combination improved the endogenous H2S and NO, and foliar‐applied MT (100 µM) led to a further increase in NO and H2S levels. In the second experiment, 0.1 mM scavenger of NO, 2‐(4‐carboxyphenyl)‐4,4,5,5‐tetramethylimidazoline‐1‐oxyl‐3‐oxide potassium salt (cPTIO) and that of H2S, hypotuarine (HT) were applied along with MT to get further evidence whether NO and H2S are involved in MT‐induced tolerance to ID and SS. MT combined with cPTIO and HT under a single or combined stress showed that NO effect was reversed by the NO scavenger, cPTIO, alone but the H2S effect was inhibited by both scavengers. These findings suggested that tolerance to ID and SS induced by MT may be involved in downstream signal crosstalk between NO and H2S.

“…This can be attributed to a greater rate of accumulation of Na + in the vacuole of leaf cells in PI 585454. A similar observation was made for the roots and shoot of salinity stresssensitive barley and rye genotype (Hu et al, 2018;Liu et al, 2018) and our findings are in accordance with their report. Similarly, the expression of HKT1 gene was highly induced in PI 585454 (Fig.…”

S ALINITY stress significantly impacts the growth, development and yield of sorghum. Knowledge about the productivity of sorghum under salinity stress condition is lagging, due to the marginally limited information about the physio-biochemical and molecular mechanisms underpinning salinity stress tolerance. The study aimed to investigate the physio-biochemical and molecular mechanisms associated with the differential responses under salinity stress condition in sorghum. To achieve our objectives, the physiological and biochemical salinity stress parameters, including membrane stability index, enzyme antioxidant activities, proline and chlorophyll contents, measured at the seedling stage, were elucidated to identify the salinity stress response status of the genotypes. The quantitative real-time polymerase chain reaction (qPCR) was perform to elucidate the expression pattern of different categories of genes under salinity stress in sorghum genotypes. From our results, enhanced enzyme antioxidant activities, membrane status, increased proline content and lower K + /Na + concentration under 300mM NaCl stress identified PI 585451 to be the most salinity stress-tolerant genotype. Nevertheless, increased MDA and Na + /K + level, lower proline, chlorophyll content and antioxidant enzyme activities in PI 585454 marked it to be sensitive to salinity stress. Besides, the transcript expression analysis of different genes, showed an upregulation in PI 585451 than in PI 585454. The results highlighted the differences in metabolic response to salinity stress that may play an important role in the provision of information, required for breeding and development of sorghum genotypes that are tolerant to salinity stress.

“…Activities of SOD increased in the shoot tissues of Kentucky bluegrass (Poa pratensis L.) and tall fescue under salinity stress, while activities of CAT and APX decreased in Kentucky bluegrass but remained unchanged in tall fescue (Xu et al 2013). Lipid peroxidation increased in the salt-sensitive perennial ryegrass (Lolium perenne L.) accession but remained unchanged in the salttolerant one (Liu et al 2018). It appears that salinity-induced alteration of antioxidant enzyme activities varies with plant species, cultivars, the stage of plant growth, and the duration and intensity of stress.…”

Endophyte-mediated salinity tolerance is largely unknown in tall fescue [Schedonorus arundinaceus (Schreb.)]. The experiment was designed to characterize growth, ion accumulation, and antioxidant metabolism of tall fescue infected by the endophyte Epichloë coenophiala to different levels of salinity stress. Endophyte-infected (E +) and endophyte-free (E−) tall fescue (cv Kentucky 31) plants were exposed to 10 d of 0 (unstressed control), 100 and 200 mM NaCl treatments in a greenhouse, respectively. Salinity stress caused reductions in plant height, leaf fresh weight (LFW), leaf dry weight (LDW), and leaf water content (LWC), and increased Na + concentration, but E + plants had significantly higher LFW, LDW, and LWC under both NaCl treatments and lower Na + than E− plants under 200 mM NaCl. Salinity stress decreased K + and Mg 2+ and did not alter P, and increased Ca 2+ in E + plants and caused no change in Ca 2+ in E− plants; however, endophyte had no effects on these elements. Chlorophyll fluorescence (Fv/Fm), malondialdehyde (MDA) concentration, and activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) remained unchanged in E + plants, but Fv/Fm was reduced and MDA level and enzyme activities were elevated in E− plants under 200 mM NaCl, where E + plants had significantly higher Fv/Fm and lower MDA, SOD, and APX activities than E− plants. Peroxidase activities increased in E + plants under 200 mM NaCl and in E− plants under both NaCl treatments. The results indicated that endophyte promoted salinity tolerance in tall fescue through maintaining higher growth and photochemical efficiency and lowering Na + accumulation and lipid peroxidation. The significantly induced antioxidant enzyme activities and lipid peroxidation in E− plants suggested a possible enhanced oxidative injury in endophyte-free plants exposed to a high level of salinity stress.
