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...

“…Reactive oxygen species (ROS) are potentially toxic to plant cells, even though these compounds play a key role in signaling (Ahmad et al, 2019). In plants, TIPs can facilitate the diffusion of hydrogen peroxide (H 2 O 2 ), which is a ROS (Shivaraj, Vats, et al, 2019). Bienert et al (2007) provided the first molecular evidence that AtTIP1;1, and AtTIP1;2 can transport H 2 O 2 across the membrane.…”

Tonoplast intrinsic proteins (TIPs), belonging to the aquaporin family, are transmembrane channels located mostly at the tonoplast of plant cells. The TIPs are known to transport water and many other small solutes such as ammonia, urea, hydrogen peroxide, and glycerol. In the present review, phylogenetic distribution, structure, transport dynamics, gating mechanism, sub-cellular localization, tissuespecific expression, and co-expression of TIPs are discussed to define their versatile role in plants. Based on the phylogenetic distribution, TIPs are classified into five distinct groups with aromatic-arginine (Ar/R) selectivity filters, typical poremorphology, and tissue-specific gene expression patterns. The tissue-specific

Although plants are permanently exposed to D-amino acids (D-AAs) in the rhizosphere, these compounds were for a long time regarded as generally detrimental, due to their inhibitory effects on plant growth. Recent studies showed that this statement needs a critical revision. There were several reports of active uptake by and transport of D-AAs in plants, leading to the question whether these processes happened just as side reactions or even on purpose. The identification and characterization of various transporter proteins and enzymes in plants with considerable affinities or specificities for D-AAs also pointed in the direction of their targeted uptake and utilization. This attracted more interest, as D-AAs were shown to be involved in different physiological processes in plants. Especially, the recent characterization of D-AA stimulated ethylene production in Arabidopsis thaliana revealed for the first time a physiological function for a specific D-AA and its metabolizing enzyme in plants. This finding opened the question regarding the physiological or developmental contexts in which D-AA stimulated ethylene synthesis are involved in. This question and the ones about the transport characteristics of D-AAs, their metabolism, and their different physiological effects, are the focus of this review.
