%X Plant releases a variety of volatile substances into the environment when they suffered from insect feeding, wound or abiotic stress, to help plant combat the damage directly or indirectly. These volatile substances can also provide a precaution for the nearby plants to cope with the incoming threat. H<sub>2</sub>S has been reported as an intracellular gasotransmitter which can increase the tolerance of plant to multiple stresses. We explored the possibility of H<sub>2</sub>S to be a plant-to-plant signaling molecule in multiple plants. The H<sub>2</sub>S concentrations in air increased when the foxtail millet, Chinese cabbage, tomato or <i>Arabidopsis</i> seedlings were treated with 40% PEG 8000. When the <i>Arabidopsis</i> or the foxtail millet was treated with PEG 8000, the H<sub>2</sub>S content and the expression levels of the H<sub>2</sub>S response genes in the neighboring non-stressed plants were increased, and the stomatal closure of these plant was also induced. However, when the lcd/des1 was treated with PEG 8000, not a similar phenomenon could be observed in the neighboring plants of this mutant. Therefore, H<sub>2</sub>S not only functions as an intracellular signal molecule, but also serves as an information transfer molecule between plant individuals, that is, by releasing H<sub>2</sub>S into the surrounding environment, plants under stress can provide early warning information of stress to their neighboring plants, which may be of great significance to the survival of the population.
