“…Stomatal conductance (‘ Gs ’), which in untreated plants was severely inhibited following the frost, was also majorly inhibited in primed plants. These observations are in line with recent findings in Arabidopsis, showing that NaHS in combination with cold stress contributed toward stomatal closure (Du et al ). This ‘negative’ effect of NaHS on stomatal conductance was also observed in Arabidopsis during drought stress (Jin et al , ).…”

“…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.

“…Thus, the accumulation of H 2 O 2 under low temperature stress caused by Hypotaurine ( Figure 10B) is an important reason for the increase of PSI photoinhibition. Some studies have reported that exogenous H 2 S improved the drought resistance of Arabidopsis thaliana by inducing stomatal closure , which was mainly due to the reduction of the stomatal diameter caused by H 2 S (Jin et al, 2011) or the increase in the expression of the mitogen activated protein kinase gene to prevent over opening of stomata under low temperature stress (Du et al, 2017). However, other studies have shown that exogenous H 2 S improved photosynthetic capacity of rice leaves by increasing stomatal aperture and density, and NaHS induced stomatal opening in Arabidopsis thaliana by inhibiting NO production (Lisjak et al, 2010).…”

In this study, we investigated the mechanism of photosynthesis and physiological function of blueberry leaves under low temperature stress (4-6°C) by exogenous hydrogen sulfide (H 2 S) by spraying leaves with 0.5 mmol·L -1 NaHS (H 2 S donor) and 200 mmol·L -1 hypotaurine (Hypotaurine, H 2 S scavenger). The results showed that chlorophyll and carotenoid content in blueberry leaves decreased under low temperature stress, and the photochemical activities of photosystem II (PSII) and photosystem I (PSI) were also inhibited. Low temperature stress can reduce photosynthetic carbon assimilation capacity by inhibiting stomatal conductance (G s ) of blueberry leaves, and non-stomatal factors also play a limiting role at the 5 th day of low temperature stress. Low temperature stress leads to the accumulation of Pro and H 2 O 2 in blueberry leaves and increases membrane peroxidation. Spraying leaves with NaHS, a donor of exogenous H 2 S, could alleviate the degradation of chlorophyll and carotenoids in blueberry leaves caused by low temperature and reduce the photoinhibition of PSII and PSI. The main reason for the enhancement of photochemical activity of PSII was that exogenous H 2 S promoted the electron transfer from Q A to Q B on PSII acceptor side under low temperature stress. In addition, it promoted the accumulation of osmotic regulator proline under low temperature stress and significantly alleviated membrane peroxidation. H 2 S scavengers (Hypotaurine) aggravated photoinhibition and the degree of oxidative damage under low temperature stress. Improving photosynthetic capacity as well as alleviating photosynthetic inhibition and oxidative stress with exogenous H 2 S is possible in blueberry seedlings under low temperature stress.

“…The MAPK is known to be an important component of signal transduction pathways and participates in drought, heavy metal exposure and cold in Arabidopsis (Furuya et al ). The MAPK response associated with cold stress was studied by Du et al () in which cold exposed Arabidopsis plant showed reduced root length which however became tolerant to the cold stress upon application of H 2 S. H 2 S also up regulates the gene expression of MAPKs (Du et al ). Expression of MPK4 gene increases the most on H 2 S treatment supporting the fact that H 2 S is involved in regulating MAPK activities (Du et al ).Similarly, other reports have also suggested the role of H 2 S in mitigation of cold stress in Arabidopsis , Bermudagrass and Lamiophlomis rotata (Shi et al , , Ma et al ).…”

Plants often face a variety of abiotic stresses, which affects them negatively and lead to yield loss. The antioxidant system efficiently removes excessive reactive oxygen species and maintains redox homeostasis in plants. With better understanding of these protective mechanisms, recently the concept of hydrogen sulfide (H2S) and its role in cell signaling has become the center of attention. H2S has been recognized as a third gasotransmitter and a potent regulator of growth and development processes such as germination, maturation, senescence and defense mechanism in plants. Because of its gaseous nature, H2S can diffuse to different part of the cells and balance the antioxidant pools by supplying sulfur to cells. H2S showed tolerance against a plethora of adverse environmental conditions like drought, salt, high temperature, cold, heavy metals and flood via changing in level of osmolytes, malonaldialdehyde, Na+/K+ uptake, activities of H2S biosynthesis and antioxidative enzymes. It also promotes cross adaptation through persulfidation. H2S along with calcium, methylglyoxal and nitric oxide, and their cross talk induces the expression of mitogen activated protein kinases as well as other genes in response to stress. Therefore, it is sensible to evaluate and explore the stress responsive genes involved in H2S regulated homeostasis and stress tolerance. The current article is aimed to summarize the recent updates on H2S‐mediated gene regulation in special reference to abiotic stress tolerance mechanism, and cross adaptation in plants. Moreover, new insights into the H2S‐associated signal transduction pathway have also been explored.
