“…Mir et al (2018) have also suggested that the pretreatment of maize seedlings with JA mitigated the toxic effects of excessive Na 2 CO 3 on plant growth and photosynthesis. Yuan et al (2018) have also reported that the exogenous application MJ alleviates the reduced growth of Limonium bicolor under salt stress. They have shown that the exposure of 300-mM NaCl inhibited seedling growth, while adverse effects of NaCl was mitigated by the exogenous application of 0.03-mM MeJA, resulting in a biomass close to the control plants.…”

Jasmonates (JAs) are universally known lipid-derived phytohormones which regulate overall plant growth under both abiotic and biotic stresses. They are helpful in developing root and reproductive system in plants. Also, JA signaling triggers gene expression. They coordinate with other plant hormones under changing environmental conditions. JAs alone or sometimes in combination with other plant hormones ameliorate stress conditions. They also participate in upregulation of antioxidant metabolism, osmolyte synthesis, and metabolite accumulation. Pretreatment and/or exogenous application of JA exhibited multi-stress resilience under changing environment as well as other biotic stress conditions. The present review focuses on our current understanding of how plants respond to JAs' application under extremely low or high temperature, highly alkaline condition, or even when attacked by herbivorous insects/animals. As a consequence of injury, the plant produces defense molecules to protect itself from damage. Their major role and mechanism of action under heavy metal/metalloid-induced toxicity have also been discussed.

There is an increasing number of studies from investigation of halophyte-specific root growth (Yuan et al, 2018;Kiani-Pouya et al, 2020). To increase the halophyte feature our crop plants can provide an environmentally sustainable solution for increased crop yield in line with food demand (Liu et al, 2020).…”

Halotropism is a sodium specific tropic movement of roots in order to obtain the optimal salt concentration for proper growth and development. Numerous results suggest that halotropic events are under the control and regulation of complex plant hormone pathway. This minireview collects some recent evidences about sodium sensing during halotropism and the hormonal regulation of halotropic responses in glycophytes. The precise hormonal mechanisms by which halophytes plant roots perceive salt stress and translate this perception into adaptive, directional growth forward increased salt concentrations are not well understood. This minireview aims to gather recently deciphered information about halotropism focusing potential hormonal aspects both in glycophytes and halophytes. Advances in our understanding of halotropic responses in different plant species could help these plants to be used for sustainable agriculture and other future applications.

“…Salt-tolerant plants called halophytes have evolved a variety of mechanisms that allow them to meet this challenge and limit the adverse effects of salt on their metabolism [8]. One type of halophyte, the recretohalophytes, secrete excess salt from salt glands or salt bladders located mainly on their leaves, thereby ensuring a lower Na + content in their shoots and avoiding the excessive accumulation of ions in their cells, which protects against salt-associated damage [9,10].…”

Background: Salt, a common environmental stress factor, inhibits plant growth and reduces yields. Melatonin is a pleiotropic molecule that regulates plant growth and can alleviate environmental stress in plants. All previous research on this topic has focused on the use of melatonin to improve the relatively low salt tolerance of glycophytes by promoting growth and enhancing antioxidant ability. It is unclear whether exogenous melatonin can increase the salt tolerance of halophytes, particularly recretohalophytes, by enhancing salt secretion from the salt glands. Results: To examine the mechanisms of melatonin-mediated salt tolerance, we explored the effects of exogenous applications of melatonin on the secretion of salt from the salt glands of Limonium bicolor (a kind of recretohalophyte) seedlings and on the expression of associated genes. A pretreatment with 5 μM melatonin significantly improved the growth of L. bicolor seedlings under 300 mM NaCl. Furthermore, exogenous melatonin significantly increased the dry weight and endogenous melatonin content of L. bicolor. In addition, this treatment reduced the content of Na+ and Cl– in leaves, but increased the K+ content. Both the salt secretion rate of the salt glands and the expression level of genes encoding ion transporters (LbHTK1, LbSOS1, LbPMA, and LbNHX1) and vesicular transport proteins (LbVAMP721, LbVAP27, and LbVAMP12) were significantly increased by exogenous melatonin treatment. These results indicate that melatonin improves the salt tolerance of the recretohalophyte L. bicolor via the upregulation of salt secretion by the salt glands.Conclusions: Our results showed that melatonin can upregulate the expression of genes encoding ion transporters and vesicle transport proteins to enhance salt secretion from the salt glands. Combining the results of the current study with previous research, we formulated a novel mechanism by which melatonin increases salt secretion in L. bicolor. Ions in mesophyll cells are transported to the salt glands through ion transporters located at the plasma membrane. After the ions enter the salt glands, they are transported to the collecting chamber adjacent to the secretory pore through vesicle transport and ions transporter and then are secreted from the secretory pore of salt glands, which maintain ionic homeostasis in the cells and alleviate NaCl-induced growth inhibition.
