The protective effect of silicon (Si) against environmental stress has been observed in many crops. The objective of this work was to evaluate the impact of SiK® (potassium silicate) fertilization on the resilience capacity of chestnut plants growing under high air temperature conditions and their recovery capacity after a turnover to adequate temperatures. Castanea sativa plants were supplied with 0 mM, 5 mM, 7.5 mM, and 10 mM SiK® and exposed sequentially to 25°C, 32°C, and 25°C for 1 month each. Data suggested that silicon are involved in increasing the heat tolerance of chestnut plants by reducing the oxidative damage and improving the antioxidant enzymes and metabolites. Under heat stress (32°C), there was an increase in the catalase, ascorbate peroxidase, and peroxidase activities, as well as in the phenol content of supplemented plants, which consequently reduced the electrolyte leakage, lipid peroxidation, and hydrogen peroxide content. Additionally, a lower proline content was measured inside the leaves' tissues of Si-treated plants. Besides the resilience against heat stress, after exposure to 32°C, the recovery was also quick.

“…Severe drought stress (75% water deficit condition) in finger millet plants considerably increased EL and H 2 O 2 content [ 87 ]. In another study, Malhotra et al [ 88 ] withheld irrigation in tomato plant for 6 d, which resulted in an increase of MDA content as well as 39% augmentation of EL. Hasanuzzaman et al [ 89 ] and [ 90 ] investigated the effect of hyperosmotic stress (10% and 20% polyethylene glycol; PEG) on Brassica napus L. cv.…”

Reactive Oxygen Species and Antioxidant Defense in Plants under Abiotic Stress: Revisiting the Crucial Role of a Universal Defense Regulator

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.
