The different levels of Cr included 0, 10, 100 and 200\u2009\u00b5M. Results reported that Cr exposure reduced growth and biomass, chlorophyll (Chl) contents, gas exchange parameters and enzymatic antioxidants. Chromium stress enhanced the production of electrolyte leakage (EL), hydrogen peroxide (H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>) and malondialdehyde (MDA) contents and increased Cr content in the roots, stem, leaf and flowers. Exogenous H<jats:sub>2<\/jats:sub>S improved the physiological and biochemical attributes of Cr\u2010stressed cauliflower. Hydrogen sulfide decreased Cr content in different parts of Cr\u2010stressed plants, whereas it increased the  Chl contents and gas exchange attributes. H<jats:sub>2<\/jats:sub>S reduced the EL, H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> and MDA concentrations, enhancing the antioxidant enzymes activities in Cr\u2010stressed roots and leaves compared to the Cr treatments alone. Collectively, our results provide an insight into the protective role of H<jats:sub>2<\/jats:sub>S in Cr\u2010stressed cauliflower and suggest H<jats:sub>2<\/jats:sub>S as a potential candidate in reducing Cr toxicity in cauliflower and other crops.<\/jats:p>","DOI":"10.1111\/ppl.13001","type":"journal-article","created":{"date-parts":[[2019,6,18]],"date-time":"2019-06-18T08:38:53Z","timestamp":1560847133000},"page":"289-300","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":179,"title":["Hydrogen sulfide alleviates chromium stress on cauliflower by restricting its uptake and enhancing antioxidative system"],"prefix":"10.1111","volume":"168","author":[{"given":"Rehan","family":"Ahmad","sequence":"first","affiliation":[{"name":"Department of Soil and Environmental Sciences Gomal University  Dera Ismail Khan Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shafaqat","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Environmental Sciences and Engineering Government College University  Faisalabad Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Rizwan","sequence":"additional","affiliation":[{"name":"Department of Environmental Sciences and Engineering Government College University  Faisalabad Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Dawood","sequence":"additional","affiliation":[{"name":"Department of Environmental Sciences Bahauddin Zakariya University  Multan Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mujahid","family":"Farid","sequence":"additional","affiliation":[{"name":"Department of Environmental Sciences University of Gujrat  Gujrat Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Afzal","family":"Hussain","sequence":"additional","affiliation":[{"name":"Department of Soil and Environmental Sciences Gomal University  Dera Ismail Khan Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonard","family":"Wijaya","sequence":"additional","affiliation":[{"name":"Botany and Microbiology Department, College of Science King Saud University  Riyadh Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed Nasser","family":"Alyemeni","sequence":"additional","affiliation":[{"name":"Botany and Microbiology Department, College of Science King Saud University  Riyadh Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2734-4180","authenticated-orcid":false,"given":"Parvaiz","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Botany and Microbiology Department, College of Science King Saud University  Riyadh Saudi Arabia"},{"name":"Department of Botany S.P.
