Physiological Implications of Hydrogen Sulfide in Plants: Pleasant Exploration behind Its Unpleasant Odour

<div>Generalized model of H<sub>2</sub>S signaling in response to abiotic stress in plants. Solid line arrows depict stimulatory effect; dashed cents arrows represent the putative interaction; gray bold rectangle indicates cell membrane. ABA: abscisic acid; CBF: C-repeat binding factor; CO: carbon monoxide; DREB: dehydration responsive element; Eth: ethylene; GA: gibberellic acid; cGMP: cyclic guanosine monophosphate; GSH: glutathione; H<sub>2</sub>O<sub>2</sub>: hydrogen peroxide; H<sub>2</sub>S: hydrogen sulfide; JA: jasmonic acid; NO: nitric oxide; PCD: programmed cell death; RD: responsive to desiccation.</div>
