In mammals, NO is produced via both nitrate/nitrite reduction and the oxidation of l-arginine by nitric oxide synthase (NOS). In plants, while the reductive pathway was identified early on, a NOS-like equivalent remained elusive for decades. In this opinion article, we describe recent discoveries that suggest a modular oxidative pathway, in which peroxidases may play a key role. Together with earlier observations, this model supports a broader conceptual framework for oxidative NO production in plants, moving beyond the expectation of animal-like homologs. This serves as a reminder that plants often solve biochemical challenges in innovative ways.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":"1303-1313"},"PeriodicalIF":21.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148006813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss how minimal art-sRNA precursors represent a versatile platform for precision RNAi and, critically, unlock RNA viruses as stable, programmable platforms for the production of highly specific art-sRNAs.
