Hydrogen sulfide: the shutter button of stomata in plants

Hydrogen Sulfide Mediates K+ and Na+ Homeostasis in the Roots of Salt-Resistant and Salt-Sensitive Poplar Species Subjected to NaCl Stress

“…Evidence increasingly shows that hydrogen sulfide (H 2 S) functions as a molecular signal that also mediates numerous physiological processes. H 2 S has been shown to regulate photosynthesis ( Chen et al, 2011 ), stomatal movement ( García-Mata and Lamattina, 2010 ; Lisjak et al, 2010 ; Jin and Pei, 2016 ; Jin et al, 2017 ), adventitious rooting ( Zhang et al, 2009a ), and flower senescence ( Zhang et al, 2011 ). The role of H 2 S in stress physiology has thus received growing attention among researchers.…”

Diversity of hydrogen sulfide concentration in plant: a little spark to start a prairie fire

“…The ubiquitous and versatile signal-transduction role of hydrogen sulfide (H 2 S) has been revealed in mammals and plants in recent years [1][2][3][4][5]. It is very important to grasp the physiological concentrations of H 2 S in vivo because of its toxic characteristics at high concentrations.…”

“…funaria (Funaria hygrometrica); 3: moss (Fantinalis antipyretica); 4: juniper (Juniperus formosana); 5: platycladus (platycladus orientalis); 6: scutellaria (Scutellaria baicalensis); 7: tomato (Lycopersicon esculentum); 8: green bean (Phaseolus); 9: wheat (Triticum aestivum); 10: cabbage (Brassica campestris); 11: pumpkin (Cucurbita moschata); 12: cucumber (Cucumis sativus); 13: clove (Syringa oblata ); 14: willow (Salix babylonica); 15: millet (Setaria italica); 16: tobacco (Nicotiana tabacum); 17: Arabidopsis (Arabidopsis thaliana). Leaves (4,5,13,14) or the whole seedlings (1-3; 6-12; 15-17) were collected to detect. Rosette leaves were collected from the plant of 2-w-, 4-w-, 6-w-, 8-w-and 10-w-old Arabidopsis (c and d); The root, stem, rosette leaf, cauline leaf, flower, seed, silique samples were isolated from 8-w-old Arabidopsis (e and f).…”

Effect of hydrogen sulfide(H2S) fumigation on quality of passionfruit (Passiflora edulis sims)

“…H 2 S in plant is mainly produced by the degradation of cysteine catalyzing by D-/L cysteine desulfhydrase or the reduction of SO 3 2by sulfite reductase [11,12] . Recently a large number of studies have shown that H 2 S acts as a second messenger participating in many plant physiological processes: regulate stomatal movement, participate in photosynthesis, respond to drought or low temperature stress, delay the senescence of postharvested fruits and vegetables, and improve the quality of horticultural products [13][14][15][16][17][18] . H 2 S fumigation on kiwifruit [19] , banana [11] , pear [6] could retard softening and reduce decay, it can be seen that H 2 S treatment can better delay fruit aging and maintain fruit storage quality after harvest.…”
