Background  Rosea1 ( Ros1 ) and Delila ( Del ) co-expression controls anthocyanin accumulation in snapdragon flowers, while their overexpression in tomato strongly induces anthocyanin accumulation. However, little data exist on how  Del  expression alone influences anthocyanin accumulation.    Results  In tobacco ( Nicotiana tabacum  ‘Xanthi’),  Del  expression enhanced leaf and flower anthocyanin production through regulating  NtCHS ,  NtCHI ,  NtF3H ,  NtDFR , and  NtANS  transcript levels. Transgenic lines displayed different anthocyanin colors (e.g., pale red: T 0 -P, red: T 0 -R, and strong red: T 0 -S), resulting from varying levels of biosynthetic gene transcripts. Under salt stress, the T 2  generation had higher total polyphenol content, radical (DPPH, ABTS) scavenging activities, antioxidant-related gene expression, as well as overall greater salt and drought tolerance than wild type (WT).    Conclusion  We propose that  Del  overexpression elevates transcript levels of anthocyanin biosynthetic and antioxidant-related genes, leading to enhanced anthocyanin production and antioxidant activity. The resultant increase of anthocyanin and antioxidant activity improves abiotic stress tolerance.
