“…In order to evaluate the specificity and efficiency of WSP‐5 in the detection of H 2 S in Arabidopsis seedlings, additional controls using Arabidopsis wild‐type (WT) seedlings were carried out. Figure A–D shows a primary root of 10‐d‐old Arabidopsis seedlings incubated with increasing concentrations (0.0, 0.1, 0.5 and 2 mmol/L) of sodium hydrosulfide NaHS which is a recognized H 2 S donor molecule in animal and plant systems (Wang et al ; Aroca et al ; Yang et al ; Kharbech et al ; Zhang et al ; Muñoz‐Vargas et al ). Thus, an increase in the red fluorescence signal corresponding to the presence of H 2 S was also observed.…”

Plant peroxisomes have the capacity to generate different reactive oxygen and nitrogen species (ROS and RNS), such as H 2 O 2 , superoxide radical (O 2 Á À ), nitric oxide and peroxynitrite (ONOO -). These organelles have an active nitrooxidative metabolism which can be exacerbated by adverse stress conditions. Hydrogen sulfide (H 2 S) is a new signaling gasotransmitter which can mediate the posttranslational modification (PTM) persulfidation. We used Arabidopsis thaliana transgenic seedlings expressing cyan fluorescent protein (CFP) fused to a canonical peroxisome targeting signal 1 (PTS1) to visualize peroxisomes in living cells, as well as a specific fluorescent probe which showed that peroxisomes contain H 2 S. H 2 S was also detected in chloroplasts under glyphosate-induced oxidative stress conditions. Peroxisomal enzyme activities, including catalase, photorespiratory H 2 O 2 -generating glycolate oxidase (GOX) and hydroxypyruvate reductase (HPR), were assayed in vitro with a H 2 S donor. In line with the persulfidation of this enzyme, catalase activity declined significantly in the presence of the H 2 S donor. To corroborate the inhibitory effect of H 2 S on catalase activity, we also assayed pure catalase from bovine liver and pepper fruit-enriched samples, in which catalase activity was inhibited. Taken together, these data provide evidence of the presence of H 2 S in plant peroxisomes which appears to regulate catalase activity and, consequently, the peroxisomal H 2 O 2 metabolism. . In plant systems, several enzymes are capable of generating H 2 S, which is part of the cysteine (Cys) metabolism. These enzymes, including L-and D-cysteine desulfhydrase (L-DES/D-DES), sulfite reductase (SiR), cyano alanine synthase (CAS) and cysteine synthase (CS) (Li et al. 2013; Calderwood and Kopriva 2014; Hancock and Whiteman 2014), are present in different subcellular compartments, such as cytosol, chloroplasts

“…One of the major sources of ROS during times of abiotic stress is the photosynthetic apparatus. Documented effects of priming treatments with H 2 S donors [NaHS or sodium sulfide (Na 2 S)] include lowered accumulation of ROS and increased expression and activities of antioxidant systems (Fu et al , Yang et al ). In accordance with these observations, herein we observed that leaves from primed avocado plants accumulated lower H 2 O 2 after being exposed to frost and high‐light conditions.…”

“…These effects were attributed to the reduced accumulation of ROS and enhanced activities of antioxidant systems, but also possibly to inhibition of ethylene synthesis and/or signaling, modulation of sugar metabolism and control of autophagic processes (recent review by Ziogas et al ). Priming of plants with H 2 S donors (most commonly NaHS) has been shown to enhance their tolerance to a multitude of abiotic stresses including high light, drought, salinity, cold, heat, freezing, osmotic and heavy metal stress (Wang et al , Jin et al , Christou et al , Fu et al , Shi et al , Fan et al , Li et al , Yang et al , Du et al ).…”

Radiation frost events, which have become more common in the Mediterranean Basin in recent years, inflict extensive damage to tropical/subtropical fruit crops. During radiation frost, sub‐zero temperatures are encountered in the dark, followed by high light during the subsequent clear‐sky day. One of the key processes affected by these conditions is photosynthesis, which, when significantly inhibited, leads to the enhanced accumulation of reactive oxygen species (ROS) and damage. The use of ‘chemical priming’ treatments that induce plants' endogenous stress responses is a possible strategy to improve their coping with stress conditions. Herein, we studied the effects of priming with sodium hydrosulfide (NaHS), a donor of hydrogen sulfide (H2S), on the response of photosynthesis to overnight frost and day high‐light conditions in ‘Hass’ avocado (Persea americana Mill). We found that priming with a single foliar application of NaHS had positive effects on the response of grafted ‘Hass’ plants. Primed plants exhibited significantly reduced inhibition of CO2 assimilation, a lower accumulation of hydrogen peroxide as well as lower photoinhibition, as compared to untreated plants. The ability to maintain a high CO2 assimilation capacity after the frost was attained on the background of considerable inhibition in stomatal conductance. Thus, it was likely related to the lower accumulation of ROS and photodamage observed in primed ‘Hass’ plants. This work contributes toward the understanding of the response of photosynthesis in a subtropical crop species to frost conditions and provides a prospect for chemical priming as a potential practice in orchards during cold winters.

Exogenous application of 5-aminolevulinic acid on wheat seedlings under drought stress enhances the transcription of psbA and psbD genes and improves photosynthesis

The compound 5-aminolevulinic acid (ALA) is an essential precursor for the biosynthesis of porphyrins, including chlorophyll, heme, and cytochromes. The protective effects of ALA on photosynthesis and the expression of photosynthetic genes in wheat under drought stress are not well understood. Two wheat cultivars, drought-tolerant Aikang-58 and droughtsensitive Chinese Spring, were exposed to drought stress induced by 20% polyethylene glycol (PEG-6000) after foliar pretreatment with ALA for 3 days. The results showed that exogenous application of ALA protected the drought-stressed wheat seedlings by significantly inhibiting the decrease in relative water and chlorophyll contents. The ALA-mediated alleviation of stress was similar between the drought-tolerant and drought-sensitive wheat cultivars. Meanwhile, compared to seedlings under drought treatment alone, the ALA-pre-treated wheat seedlings under drought stress maintained higher photosystem II (PSII) functional indexes. The ALA pretreatment reduced the drought-driven accumulation of both H 2 O 2 and ABA and increased the stomatal conductance. Real-time PCR analysis showed that the psbA and psbD gene transcripts were both upregulated under drought stress following ALA pretreatment. The present study suggests that the exogenous foliar application of ALA alleviates the drought stress on wheat seedlings, which is associated with the enhancement of PSII function by inducing chlorophyll synthesis and psbA and psbD transcription. Moreover, the protective effect of ALA pretreatment was not related to the decline in stomatal conductance caused by ABA or H 2 O 2 accumulation.
