“…Recently, Cheng et al [71] reported that the total ROS content, lipid peroxidation, and electrolyte leakage (EL) in rice root tissues were two times higher under salt stress compared with the control. In another study, Ahanger et al [72] reported an overaccumulation of O plants, suggesting a link between the antioxidant defense apparatus and their increased invasiveness in adverse environments [79]. From these examples, it is evident that plants have differential responses towards salt-induced oxidative stress conditions.…”

Global climate change and associated adverse abiotic stress conditions, such as drought, salinity, heavy metals, waterlogging, extreme temperatures, oxygen deprivation, etc., greatly influence plant growth and development, ultimately affecting crop yield and quality, as well as agricultural sustainability in general. Plant cells produce oxygen radicals and their derivatives, so-called reactive oxygen species (ROS), during various processes associated with abiotic stress. Moreover, the generation of ROS is a fundamental process in higher plants and employs to transmit cellular signaling information in response to the changing environmental conditions. One of the most crucial consequences of abiotic stress is the disturbance of the equilibrium between the generation of ROS and antioxidant defense systems triggering the excessive accumulation of ROS and inducing oxidative stress in plants. Notably, the equilibrium between the detoxification and generation of ROS is maintained by both enzymatic and nonenzymatic antioxidant defense systems under harsh environmental stresses. Although this field of research has attracted massive interest, it largely remains unexplored, and our understanding of ROS signaling remains poorly understood. In this review, we have documented the recent advancement illustrating the harmful effects of ROS, antioxidant defense system involved in ROS detoxification under different abiotic stresses, and molecular cross-talk with other important signal molecules such as reactive nitrogen, sulfur, and carbonyl species. In addition, state-of-the-art molecular approaches of ROS-mediated improvement in plant antioxidant defense during the acclimation process against abiotic stresses have also been discussed.

“…Changes in morphological appearance in response to salinity stress are not enough to determine the effect and subsequently design the management strategies. It is therefore important to identify key physiological and biochemical factors for improving the salinity tolerance of plants (Munns and Tester 2008;Ahanger and Agarwal 2017;Ahanger et al 2020). To date, three main mechanisms contributing to shoot tissue tolerance to salinity have been targeted: accumulation of Na + in the vacuole, synthesis of compatible solutes and production of enzymes catalyzing detoxification of ROS.…”

“…Brassinosteroids (BRs) are a plant hormone, which support cultivated plants in the growth, development and stress tolerance (Tong andChu, 2018 andPandey et al, 2020). Brassinosteroid is "poly-hydroxylated steroid phyto-hormone" having unique key roles during the early development of seedlings, flowering stage, vascular development and development of roots (Lee et al 2018;Ahanger et al 2020;Setsungnern et al 2020).The tolerance of plants towards stress may depend on the interaction between BRs and other phytohormones including auxin, cytokinins, salicylic acid, and ethylene (Ahanger et al, 2020). It is reported about the promising role of appliedBRs in protecting the environment under stress (Soares et al, 2020).…”

“…It is reported about the promising role of appliedBRs in protecting the environment under stress (Soares et al, 2020). Exogenous applied and endogenous BRs was found to increase the tolerance of tomato plants against different stresses such as salinity (Ahanger et al 2020), drought (Jangid and Dwivedi, 2017, Lee et al, 2018and Nie et al, 2019, low temperature stress (Khan et al, 2019) and for other stressed plants like heat stress on Arabidopsis (Setsungnern et al, 2020), cadmium stress on pepper (Kaya et al, 2020), lead stress on Brassica juncea (Soares et al, 2020) and heat stress on barley (Sadura et al, 2020).Therefore, BRs are plant growth regulators that recognize the promoting the division and stretching of plant cells, vascular differentiationandthe resistance against stressful conditions (Soares et al, 2020).…”

T HE production of protected cultivation of vegetables could be considered as a sustainable solution in arid and semi-arid regions.These regions already suffer from raising temperature andthe global warmingwill aggravate this, whichrepresents a great challenge facing our universe nowadays. Hence, the production of vegetables and tomato under greenhouse system during the high temperatures may be considered a serious problem should be avoided in these arid zonesin summer due to heat stress.The heat stress may cause a lot of troubles for the tomato seedlings in greenhouses in summer starting with the photosynthetic rate, and the metabolism processes in seedlings and in turn the growth and development of these seedlings. Although studies have recognized heat stress on tomato seedlings, research has yet to systematically investigate the effect of heat stress on tomato seedlings in greenhouse in summer under arid and semi-arid regions particularly in developing countries, which their greenhouses have not any climate controllers. Therefore, the management of tomato seedlings may need to address the production problems caused by heat stress in greenhouse conditions particularly in arid and semi-arid zones
