“…These stresses adversely influence the growth and yield of plants (Husen et al 2014;Getnet et al 2015;Embiale et al 2016;Bernal-Vicente et al 2018;Yurchenko et al 2018;Balfagón et al 2018). Even though plant hormones are produced in very low amounts, they regulate many external and internal stimuli (Kazan 2015;Siddiqi and Husen 2017;Pandey et al 2017;Husen et al 2018Husen et al , 2019Pandey et al 2017;Podlešáková et al 2019). They play a vital role in saving the plant from stress and improve quality of crops (Kazan 2013;Santino et al 2013;Colebrook et al 2014;Husen et al 2016Husen et al , 2017Husen et al , 2018Hanaka et al 2018).…”

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.

“…The ROS production leads to chlorophyll deprivation and membrane lipid peroxidation (measured as malondialdehyde content), reducing the membrane fluidity and selectivity [13,14]. The most affected parameters include the net photosynthetic rate (P N ) and water use efficiency (WUE), which ultimately restrict the plant growth rate [3,15,16]. The decline in photosynthesis under salinity stress may be due to inhibition of photosystem II complex and a loss of chlorophyll pigments [17].…”

Background: Soil salinity is considered as one of the major environmental factors that has reduced plant productivity worldwide. This study investigates the impact of salinity on plant growth attributes, biochemical and physiological leaf characteristics in two cultivars (Adet and Merawi) of Brassica carinata and also explores the role of salicylic acid (SA) in mitigating the effect of salt stress. Methods: Four-week-old cultivars were treated with NaCl (50, 100 and 150 mM) and SA (0.5 mM) and watered regularly with 100% field capacity. Thus, they were grown under eight different treatments (T1 = no NaCl, no SA; T2 = 0 mM NaCl with 0.5 mM SA; T3 = 50 mM NaCl without SA; T4 = 50 mM NaCl with 0.5 mM SA; T5 = 100 mM NaCl without SA; T6 = 100 mM NaCl with 0.5 mM SA; T7 = 150 mM NaCl without SA; and T8 = 150 mM NaCl with 0.5 mM SA). Nine-week-old cultivars were sampled for analyzing the growth attributes, plant water status, nitrate reductase activity, proline accumulation, photosynthetic traits, lipid peroxidation level and activity of antioxidant enzymes. Results: Salinity treatments hampered the overall plant growth performance in a dose-dependent manner. Salinity also reduced photosynthetic efficiency by inhibiting chlorophyll synthesis, nitrate reductase activity, chlorophyll fluorescence, stomatal conductance, net photosynthetic and transpiration rates and plant water status. On the other hand, SA application alleviated the adverse effects of salinity and improved the performance of the studied parameters in both the cultivars. Higher dose of salinity increased proline production, but SA application mitigates this impact in both the cultivars studied. The activity of antioxidant enzymes increased under salt stress in a dose-dependent manner. SA treatment to normal or salinity-stressed plants increased the enzymes activity, showing that SA has a crucial role in modulating the cell redox balance and protecting the plants from oxidative damage. SA significantly reduced the salinity-caused effects on the overall performance of plants and their antioxidant systems in both the cultivars. Of the two cultivars, Adet was more tolerant to salinity than Merawi. Conclusions: Foliar application of SA improved the performance of Ethiopian mustard cultivars and mitigated the damage caused by salt stress.

“…When plants are exposed to external stresses like saline, and water, heat the level of phytohormones like abscisic acid (ABA) (known as the plant stress hormone), indole-3-acetic acid (IAA) concentrations increase. Along with this, salicylic acid (SA), ethylene (ET), and jasmonates (JAs) have also specific activities under stress conditions ( Mishra et al., 2016 ; Siddiqi and Husen 2019 ; Husen et al., 2018 , 2019 ). Thus, researchers can monitor the plant abiotic stress responses through the detection of the phytohormones ( Ansari et al., 2020 ).…”
