“…In contrast to Indica, Japonica rice showed a relatively high, but constant, activity of CAT [ 32 ]. A similar increase of SOD and CAT activity was observed C. bursa-pastoris [ 9 ], Citrullus lanatus [ 34 ], and C. dactylon [ 25 ]. Therefore, SOD and CAT activity could play an important part during chilling stress, although some species like C. officinalis [ 10 ] and P. vulgaris [ 30 ] fail to increase the activity of these enzymes.…”

“…However, activity measurements usually cannot easily discriminate among the isoforms of Mn-, CuZn- and Fe-SOD. The transcript amounts and activity of SOD increase during low-temperature treatment in Capsella bursa pastoris L. [ 9 ] and Calendula officinalis [ 10 ]. The SOD activity in Calendula officinalis rises less than the transcript amount pointing to posttranscriptional regulation of synthesis or higher protein degradation rates [ 10 , 29 ].…”

“…The APX activity decreased in C. bursa pastoris during cold treatment of 1 to 5 days duration. This is quite unexpected in the light of high transcript levels observed during the first 24 h of low-temperature treatment [ 9 ] and could be due to posttranscriptional regulation [ 37 , 38 ] or APX inactivation by reaction with H 2 O 2 in the absence of ascorbate [ 39 ]. APX inactivation could be a means to enable H 2 O 2 accumulation for signaling.…”

Reactive Oxygen Species and the Redox-Regulatory Network in Cold Stress Acclimation

Cold temperatures restrict plant growth, geographical extension of plant species, and agricultural practices. This review deals with cold stress above freezing temperatures often defined as chilling stress. It focuses on the redox regulatory network of the cell under cold temperature conditions. Reactive oxygen species (ROS) function as the final electron sink in this network which consists of redox input elements, transmitters, targets, and sensors. Following an introduction to the critical network components which include nicotinamide adenine dinucleotide phosphate (NADPH)-dependent thioredoxin reductases, thioredoxins, and peroxiredoxins, typical laboratory experiments for cold stress investigations will be described. Short term transcriptome and metabolome analyses allow for dissecting the early responses of network components and complement the vast data sets dealing with changes in the antioxidant system and ROS. This review gives examples of how such information may be integrated to advance our knowledge on the response and function of the redox regulatory network in cold stress acclimation. It will be exemplarily shown that targeting the redox network might be beneficial and supportive to improve cold stress acclimation and plant yield in cold climate.

“…Xinyan 4) seedling exposed to LT [15/8 • C day/night, 8 d] stress [200]. Moreover, significantly increased CAT activity was observed in Cynodon dactylon, Capsella bursa pastoris, and Citrus reticulata, during LT stress [201][202][203]. Contrarily, higher APX activity was observed in Jatropha macrocarpa as a response to high H 2 O 2 , which improved LT stress tolerance, whereas reduced APX activity (>6-fold) in J. curcas was linked with increased sensitivity under LT conditions [204].…”

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

et al. 2020

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.

“…These osmoprotective compounds improve the antioxidant defense system of plants by directly scavenging toxic ROS and protecting key antioxidant enzymes (Hasanuzzaman et al 2014). Moreover, osmoprotectants play their role in the activation of defense related genes under various stresses (Wani et al 2018). Thus, osmoprotectants in plants are an important and well-organized evolutionary strategy to survive under hostile environments.…”
