Formation and Shaping of the Antirrhinum Flower through Modulation of the CUP Boundary Gene [Current Biology]

par Frédéric Magné - publié le

Boundary domain genes, expressed within or around organ primordia, play a key role in the formation, shaping, and subdivision of planar plant organs, such as leaves. However, the role of boundary genes in formation of more elaborate 3D structures, which also derive from organ primordia, remains unclear. Here we analyze the role of the boundary domain gene CUPULIFORMIS (CUP) in formation of the ornate Antirrhinum flower shape.(...)
