Plant Sci."],"abstract":"<jats:p>\n                    Improving growth and productivity of plants that are vulnerable to environmental stresses, such as heavy metals, is of significant importance for meeting global food and energy demands. Because heavy metal toxicity not only causes impaired plant growth, it has also posed many concerns related to human well-being, so mitigation of heavy metal pollution is a necessary priority for a cleaner environment and healthier world. Hydrogen sulfide (H\n                    <jats:sub>2<\/jats:sub>\n                    S), a gaseous signaling molecule, is involved in metal-related oxidative stress mitigation and increased stress tolerance in plants. It performs multifunctional roles in plant growth regulation while reducing the adverse effects of abiotic stress. Most effective function of H\n                    <jats:sub>2<\/jats:sub>\n                    S in plants is to eliminate metal-related oxidative toxicity by regulating several key physiobiochemical processes. Soil pollution by heavy metals presents significant environmental challenge due to the absence of vegetation cover and the resulting depletion of key soil functions. However, the use of stress alleviators, such as H\n                    <jats:sub>2<\/jats:sub>\n                    S, along with suitable crop plants, has considerable potential for an effective management of these contaminated soils. Overall, the present review examines the imperative role of exogenous application of different H\n                    <jats:sub>2<\/jats:sub>\n                    S donors in reducing HMs toxicity, by promoting plant growth, stabilizing their physiobiochemical processes, and upregulating antioxidative metabolic activities. In addition, crosstalk of different growth regulators with endogenous H\n                    <jats:sub>2<\/jats:sub>\n                    S and their contribution to the mitigation of metal phytotoxicity have also been explored.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2020.545453","type":"journal-article","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T23:26:15Z","timestamp":1609975575000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":70,"title":["Role of Exogenous and Endogenous Hydrogen Sulfide (H2S) on Functional Traits of Plants Under Heavy Metal Stresses: A Recent Perspective"],"prefix":"10.3389","volume":"11","author":[{"given":"Muhammad Saleem","family":"Arif","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tahira","family":"Yasmeen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zohaib","family":"Abbas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shafaqat","family":"Ali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Rizwan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nada H.","family":"Aljarba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saad","family":"Alkahtani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed M.","family":"Abdel-Daim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,1,7]]},"reference":[{"key":"B1","first-page":"1569","article-title":"Effect of cadmium on seed germination and seedling growth of four wheat (Triticum aestivum L.) cultivars.","volume":"5","author":"Ahmad","year":"2012","journal-title":"Pak.
