“…However, SA also participates in several processes during plant development, such as seed germination, growth, development, stomatal regulation, photosynthesis and fruit ripening (Khan et al 2003; He et al 2010; Pérez‐Llorca et al, 2019). NO signalling is also known to regulate plant growth, development and stress responses in association with other key regulators (Sanz et al, 2015; Asgher et al, 2017; Mukherjee & Corpas, 2020; Prakash et al, 2020). Based on cellular conditions, NO and SA enter into either synergistic or antagonistic relationships in plant development (Rivas‐San Vicente & Plasencia 2011).…”

The free radical nitric oxide (NO) and the phenolic phytohormone salicylic acid (SA) are signal molecules which exert key functions at biochemical and physiological levels. Abiotic stresses, especially in early plant development, impose the biggest threats to agricultural systems and crop yield. These stresses impair plant growth and subsequently cause a reduction in root development, affecting nutrient uptake and crop productivity. The molecules NO and SA have been identified as robust tools for efficiently mitigating the negative effects of abiotic stress in plants. SA is engaged in an array of tasks under adverse environmental situations. The function of NO depends on its cellular concentration; at a low level, it acts as a signal molecule, while at a high level, it triggers nitro-oxidative stress. The crosstalk between NO and SA involving different signalling molecules and regulatory factors modulate plant function during stressful situations. Crosstalk between these two signalling molecules induces plant tolerance to abiotic stress and needs further investigation. This review aims to highlight signalling aspects of NO and SA in higher plants and critically discusses the roles of these two molecules in alleviating abiotic stress.

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 well demonstrated that there is a crosstalk of ROS and NO in many developmental processes [ 63 ], including the establishment of root architecture [ 49 ]. We tested, therefore, whether this crosstalk operates in the At crk5-1 mutant roots.…”

“…Of note: the NO depleted roots exhibit elevated levels of reactive oxygen species (ROS) [ 46 ]. The crosstalk between NO and ROS is well demonstrated during various developmental processes including the organization of the root system [ 49 ]. Altogether, the experimental observations indicate that keeping the NO level in an optimal range is required for sustained root growth and development [ 50 ].…”

The Arabidopsis AtCRK5 protein kinase is involved in the establishment of the proper auxin gradient in many developmental processes. Among others, the Atcrk5-1 mutant was reported to exhibit a delayed gravitropic response via compromised PIN2-mediated auxin transport at the root tip. Here, we report that this phenotype correlates with lower superoxide anion (O2•−) and hydrogen peroxide (H2O2) levels but a higher nitric oxide (NO) content in the mutant root tips in comparison to the wild type (AtCol-0). The oxidative stress inducer paraquat (PQ) triggering formation of O2•− (and consequently, H2O2) was able to rescue the gravitropic response of Atcrk5-1 roots. The direct application of H2O2 had the same effect. Under gravistimulation, correct auxin distribution was restored (at least partially) by PQ or H2O2 treatment in the mutant root tips. In agreement, the redistribution of the PIN2 auxin efflux carrier was similar in the gravistimulated PQ-treated mutant and untreated wild type roots. It was also found that PQ-treatment decreased the endogenous NO level at the root tip to normal levels. Furthermore, the mutant phenotype could be reverted by direct manipulation of the endogenous NO level using an NO scavenger (cPTIO). The potential involvement of AtCRK5 protein kinase in the control of auxin-ROS-NO-PIN2-auxin regulatory loop is discussed.
