Quinoa (Chenopodium quinoa Willd.), often referred to as the “golden grain”, is a highly nutritious crop that has garnered significant global attention due its exceptional nutritional profile and health benefits. Flavonoids present in have been shown possess antioxidant, anti-inflammatory, antiviral, anticancer, antidepressant properties. The DNA binding with one finger (Dof) transcription factor crucial for regulating growth, development, stress responses. However, identification of Dof family using latest genomic data function abiotic response not fully elucidated. Here, 36 CqDof genes were identified from genome classified into ten subfamilies through phylogenetic analysis. Physicochemical property analysis predicted CqDofs predominantly encode basic, hydrophilic, unstable nuclear proteins. distributed across 15 chromosomes, segmental duplication being primary driver their expansion. Subsequently, basic information on was systematically analyzed, including conserved motifs, gene structure, cis-acting elements, expression patterns. Notably, promoter regions all enriched elements related light responsiveness. Further revealed red blue significantly affected flavonoid accumulation (epigallocatechin, rutin, naringenin, morin, pinocembrin, quercetin-7-O-rutinoside, quercetin-3-O-glucoside, naringenin), which 5 exhibited pronounced both conditions showed correlation levels. Finally, RT-PCR indicated levels (except CqDof21) upregulated under drought, salt, saline-alkali stresses. These findings lay groundwork future studies how regulate biosynthesis different qualities stress.
