This study investigated the impacts of different light on isoflavonoid accumulation through integrated transcriptome and metabolome analyses. Compared to white light, red and blue light treatments significantly altered the expression of 93 genes within the isoflavonoid biosynthetic pathway, 52 of which were up-regulated. Metabolomic analysis revealed 35 differential isoflavonoid metabolites, with 23 compounds, including the primary medicinal components calycosin (CA) and formononetin (FO), showing increased accumulation.

Physicochemical component analysis revealed sucrose as the major driver of SSC accumulation. Five key candidate genes (<i>MELO3C024714.2</i>, <i>MELO3C026992.2</i>, <i>MELO3C012177.2</i>, <i>MELO3C007562.2</i>, and <i>MELO3C007563.2</i>) showed differential expression within the lipid metabolism-glyoxylate cycle-gluconeogenesis pathway, implicating their synergistic involvement in energy metabolism and cellular homeostasis. In conclusion, our multiomics approach identifies a robust set of candidate genes modulating melon SSC, providing mechanistic insights into fruit flavor formation and offering valuable genetic targets for marker-assisted or genomics-informed breeding of high-quality melons.</p>","PeriodicalId":57479,"journal":{"name":"园艺研究(英文)","volume":"13 10","pages":"uhag196"},"PeriodicalIF":9.5,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13630446/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149119306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
