Functional analysis of the ScAG and ScAGL11 MADS-box transcription factors for anthocyanin biosynthesis and bicolour pattern formation in Senecio cruentus ray florets.

ABSTRACT: Cineraria (Senecio cruentus) is an ornamental plant with pure colour and bicolour cultivars, widely used for landscaping. Anthocyanin biosynthesis influences coloration patterns in cineraria. However, how anthocyanins accumulate and distribute in cineraria is poorly understood. This study investigated the molecular mechanisms underlying anthocyanin biosynthesis and bicolour formation in cineraria using pure colour and bicolour cultivars. Transcriptome and gene expression analysis showed that five genes, ScCHS2, ScF3H1, ScDFR3, ScANS, and ScbHLH17, were inhibited in the white cultivar and colourless regions of bicolour cultivars. In contrast, two MADS-box genes, ScAG and ScAGL11, showed significantly higher expression in the colourless
