In this experiment, peaches were immersed in solutions of NO, potassium 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (c-PTIO, as an NO scavenger), N-nitro-l-arginine methyl ester (l-NAME, as an inhibitor of nitric oxide synthase (NOS)-like activity), and sodium tungstate (as an inhibitor of nitrate reductase), and the resulting changes in the H2S metabolism of peaches were studied. The results showed that exogenous NO reduced the contents of endogenous H2S, Cys, and sulfite; decreased the activities of l-\/d-cysteine desulfhydrase (l-\/d-CD), O-acetylserine (thiol)lyase (OAS-TL), and sulfite reductase (SiR); and increased the activity of \u03b2-cyanoalanine synthase (\u03b2-CAS). Both c-PTIO and sodium tungstate had similar roles in increasing the H2S content by sustaining the activities of l-\/d-CDs, OAS-TL, and SiR. l-NAME increased the H2S content, mainly by maintaining the d-CD activity. The results suggest that NO, c-PTIO, l-NAME, and sodium tungstate differently regulate the H2S metabolism of peaches during storage.<\/jats:p>","DOI":"10.3390\/antiox8090401","type":"journal-article","created":{"date-parts":[[2019,9,17]],"date-time":"2019-09-17T03:31:46Z","timestamp":1568691106000},"page":"401","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Regulation of Hydrogen Sulfide Metabolism by Nitric Oxide Inhibitors and the Quality of Peaches during Cold Storage"],"prefix":"10.3390","volume":"8","author":[{"given":"Biao","family":"Geng","sequence":"first","affiliation":[{"name":"College of Chemistry and Material Science, Shandong Agricultural University, Taian 271018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dandan","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Science, Shandong Agricultural University, Taian 271018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9463-8536","authenticated-orcid":false,"given":"Shuhua","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Science, Shandong Agricultural University, Taian 271018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"50","DOI":"10.1016\/j.envexpbot.2018.08.034","article-title":"Hydrogen sulfide and environmental stresses","volume":"161","author":"Hancock","year":"2019","journal-title":"Environ.
