Abstract excerpt

KEY MESSAGE: VwMYB1 directly activates VwF3'5'H to drive delphinidin accumulation, establishing a core regulatory module controlling pansy petal blotch formation. Anthocyanins play a pivotal role in determining the visual characteristics of ornamental plants. To elucidate the molecular basis of the distinctive "blotch" formation in pansy (Viola × wittrockiana), this study employed an integrated approach that...
