Divergent genetic mechanisms underlie reversals to radial floral symmetry from diverse zygomorphic flowered ancestors
Malpighiaceae possess flowers with a unique bilateral symmetry (zygomorphy), which is a hypothesized adaptation associated with specialization on neotropical oil bee pollinators. Gene expression ofExpand
