|a Anthocyanins are one of the key metabolites influencing the coloration of ornamental bracts in plants. Curcuma alismatifolia is an emerging ornamental plant, known for the rich diversity in the coloration of its bracts and the variety of anthocyanins present. However, the specific anthocyanin metabolites contributing to this diversity are not entirely clear. This study examines the bract color variation across 19 C. alismatifolia varieties using colorimetric analysis and spectrophotometric determination of total anthocyanin content. The 19 accessions were categorized into four color groups: white, light pink, pink, and purple. Further analysis using anthocyanin metabolomics and transcriptomics was conducted on five C. alismatifolia varieties with significant differences in coloration and total anthocyanin content. In addition to previously reported anthocyanins, delphinidin-3-O-glucoside and peonidin-3-O-rutinoside were identified for the first time as important contributors to the diverse bract coloration in C. alismatifolia. Fifty-three differentially expressed genes (DEGs) were identified in the anthocyanin biosynthesis pathway, and two significant gene modules were determined through WGCNA analysis. Correlation network analysis revealed two BZ1 genes that may be key terminal enzyme genes affecting anthocyanin synthesis in C. alismatifolia bracts. Multiple transcription factors, including MYB, NAC, WRKY, ERF, and bHLH, may be involved in regulating the accumulation of different anthocyanin contents in the bracts. This research sheds light on the genetic and metabolic factors that influence bract coloration in C. alismatifolia
