Summary
For chrysanthemums--one of the world's most commercially valuable ornamental flowers--color is everything. Yet the very hormone that helps fruits ripen and leaves fall also acts as a potent silencer of floral pigmentation. A new study has uncovered the precise molecular chain of command through which ethylene turns off anthocyanin production, the pigment responsible for the rich reds, purples, and pinks that define marketable flower varieties. The findings reveal a two-tiered regulatory cascade that could reshape how breeders think about color stability and open new avenues for engineering flower traits with greater precision.
