Study reveals key gene in Delphinium petal differentiation

A recent study investigated the role of the APETALA3–3 ortholog in shaping the diverse morphologies of petals in Delphinium anthriscifolium. This gene, previously known for its function in petal identity, is now revealed to be a key player in the intricate process of petal differentiation, offering a profound understanding of floral evolution and opening avenues for future botanical research and breeding innovations.
