“…It is thought that reductions in sizes of stomatal structures (width/length) on both surfaces of leaves can have simillar outcomes. It is also thought that these reductions can be caused by impaired cell elongation or a decrease in elongated cells [54].…”

“…However, Szalai et al (2005) observed that in maize plants there were no changes in the level of endogenous SA under salt stress. In some plant species, like melon, spinach, and tomato, the content of ethylene is lower under saline than under control conditions (Zapata et al 2004).…”

Treatment with 300 mM NaCl increased the capacity of the alternative respiratory pathway and induced the expression of AOX1a of the leaves of rice (Oryza sativa L.) seedlings. A significant increase in the content of hydrogen peroxide (H2O2) was observed in rice leaves treated with 300 mM NaCl. However, NaCl at 150 mM did not significantly affect the capacity of the alternative respiratory pathway, the content of H2O2, and the transcript level of AOX1a. Exogenous application of H2O2 enhanced the levels of the capacity of the alternative respiratory pathway and AOX1a expression. The accumulation of H2O2 in rice leaves in response to 300 mM NaCl was inhibited by the pretreatment with dimethylthiourea (DMTU, scavenger of H2O2). This treatment also suppressed the induction of AOX1a expression and the increase in the capacity of the alternative respiratory pathway under 300 mM NaCl stress. Moreover, the salt-stressed (300 mM NaCl) seedlings pretreated with 1 mM salicylhydroxamic acid (SHAM, a special inhibitor of alternative oxidase) had higher level of H2O2 production than the seedlings either subjected to 300 mM NaCl stress or SHAM treatment alone did. These observations suggest that the expression of AOX1a in response to higher salt stress is mediated through an accumulation of H2O2 and alternative oxidase could play a role in antioxidant protection under the condition of higher salt stress.

“…As a salt-sensitive crop, shoot growth in maize is strongly inhibited in the first phase of salt stress (Pitann et al 2009a, b;Szalai and Janda 2009;El Sayed 2011;Wakeel et al 2011a). De Costa et al (2007) observed stunted maize growth with dark green leaves without any toxicity symptoms during the first phase of salt stress, owing to impaired extension growth as osmotic adjustment and turgor maintenance were not limiting.…”

Maize is grown under a wide spectrum of soil and climatic conditions. Maize is moderately sensitive to salt stress; therefore, soil salinity is a serious threat to its production worldwide. Understanding maize response to salt stress and resistance mechanisms and overviewing management options may help to devise strategies for improved maize performance in saline environments. Here, we reviewed the effects, resistance mechanisms, and management of salt stress in maize. Our main conclusions are as follows: (1) germination and stand establishment are more sensitive to salt stress than later developmental stages. (2) High rhizosphere sodium and chloride decrease plant uptake of nitrogen, potassium, calcium, magnesium, and iron. (3) Reduced grain weight and number are responsible for low grain yield in maize under salt stress. Sink limitations and reduced acid invertase activity in developing grains is responsible for poor kernel setting under salt stress. (4) Exclusion of excessive sodium or its compartmentation into vacuoles is an important adaptive strategy for maize under salt stress. (5) Apoplastic acidification, required for cell wall extensibility, is an important indicator of salt resistance, but not essential for better maize growth under salt stress. (6) Upregulation of antioxidant defense genes and β-expansin proteins is important for salt resistance in maize. (7) Arbuscular mycorrhizal fungi improve salt resistance in maize due to better plant nutrient availability. (8) Seed priming is an effective approach for improving maize germination under salt stress. (9) Integration of screening, breeding and ion homeostasis mechanisms into a functional paradigm for the whole plant may help to enhance salt resistance in maize.
