Phylogenetics and the evolution of major structural characters in the giant genus Euphorbia L. (Euphorbiaceae).
Euphorbia is among the largest genera of angiosperms, with about 2000 species that are renowned for their remarkably diverse growth forms. To clarify phylogenetic relationships in the genus, we usedExpand

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
