“…Several studies showed that ROS are essential for the success of numerous fundamental natural processes, including cellular proliferation and differentiation [ 11 ]. In addition, H 2 O 2 is a critical component of stress response regulation in crop plants such as rice [ 13 ], wheat [ 14 ], maize [ 15 ], mung bean [ 16 ], soybean [ 17 ], cucumber [ 18 ], sour orange [ 19 ], strawberry [ 20 ], basil [ 21 ], and rapeseed [ 22 ]. Moreover, it is established that in addition to ROS, reactive nitrogen species (RNS), reactive sulfur species (RSS), and reactive carbonyl species (RCS) also play a key signaling role and are all involved in a cross-talk in plant abiotic stress tolerance [ 23 ].…”

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.

“…Kushwaha and Singh (2019) and Ahmad et al (2019) have reported various mechanisms through which H 2 S regulates chromium toxicity in crop plants. Regulatory roles of NO and H 2 S were reported for salt and drought stress, as well as iron deficiency in plants (Batista et al 2019, Gohari et al 2019, Jahan et al 2019, Kaya et al 2019a). The role of NO and H 2 S along with that of Si was evaluated for the regulation of cadmium stress in plants (Kaya et al 2019b).…”

In the past decade, hydrogen sulfide (H 2 S) and nitric oxide (NO) have emerged as major signaling molecules which are involved in most life cycle processes in plants, i.e. from seed germination to plant death. H 2 S and NOregulated development of plants requires integration of complex signaling networks and also involves other signaling pathways. Moreover, to re-establish cellular redox homeostasis under stress conditions, regulation of gene expression takes place, which helps in achieving an appropriate plant response. In this context, the most significant controls occur at the transcriptional, posttranscriptional and post-translational levels which help in acquiring adaptive changes in stress-challenged plants. Although various studies have demonstrated the role of H 2 S and NO in regulating a plethora of plant growth and development processes under stressed/nonstressed conditions, much remains to be elucidated regarding their roles in plant biology. Therefore, this special issue was organized to collect state-of-the-art plant research involving H 2 S and NO under changing environmental conditions. This special issue has collected seven reviews and 11 original research articles aimed at compiling a comprehensive status quo on the implication of H 2 S and NO signaling in plant biology.Review articles herein provide an up-to-date coverage of existing progress in this continuously growing research area. Prakash et al. (2019) have examined the role of NO and ROS (reactive oxygen species) in governing root system architecture in plants. Rai et al. (2019) have given an overview of NO and salicylic acid signaling towards acquired heat tolerance in plants. Paul and Roychoudhury (2019), Pandey and Gautam (2019) and Singh et al. (2019) have covered exhaustive current roles of H 2 S and NO in plants under changing environmental conditions. Finally, Sharma et al. (2019) and Shivaraj et al. (2019) have discussed molecular mechanisms and crosstalk of NO and H 2 S in metal stress tolerance. Research articles have covered diverse new roles of H 2 S and NO in regulating abiotic stress in plants. Kushwaha and Singh (2019) and Ahmad et al. (2019) have reported various mechanisms through which H 2 S regulates chromium toxicity in crop plants. Regulatory roles of NO and H 2 S were reported for salt and drought stress, as well as iron deficiency in plants (Batista et al. 2019, Gohari et al. 2019, Jahan et al. 2019, Kaya et al. 2019a). The role of NO and H 2 S along with that of Si was evaluated for the regulation of cadmium stress in plants (Kaya et al. 2019b). Muñoz-Vargas et al. (2019) have noticed inhibition of NADP-malic enzyme activity by H 2 S and NO in sweet pepper. Furthermore, the role of H 2 S was examined in regulating photosynthesis under overnight frost and daytime high light in avocado (Joshi et al. 2019). Finally, Kataria et al. (2019) have reported crucial role of nitrate reductase-dependent production of NO in regulating magnetopriming-induced salt tolerance in soybean.All together, this collection of articles pres...

“…It is accepted that NO has basic and essential role in root development and also under stress conditions (Corpas and Barroso, 2015). NO can interact with other signal compounds, like hydrogen peroxide or hydrogen sulfide, which are also able to produce endogenously (Corpas et al, 2019;Gohari et al, 2020;Singh et al, 2020). NO could mediate auxin accumulation and signaling in Arabidopsis and decrease the size of root meristem size during salt stress (Liu et al, 2015).…”

“…Stress factors usually occur combined combination to each other affecting RSA (Osthoff et al, 2019;Sewelam et al, 2020). There is an increasing evidence about significance of root tropism in adjusting root system to changing conditions due to global climate change and inadequate agricultural procedures (Rozema and Schat, 2013;Gohari et al, 2020;Zhao et al, 2020). Halotropism can help roots to navigate and remodel their system architecture by cost effective energy supply in order to successfully survive during different salt conditions.…”

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.
