XVI International Botanical Congess

Phylogenetic relationship among all genera of Oleaceae were reconstructed based on the chloroplast DNA restriction site variation, chloroplast ndhF sequences, nuclear ITS sequences, and morphological characters. Four data show congruent phylogeny and support the paraphyly of subfamily Jasminoideae and the monophyly of subfamily Oleoideae. The Oleoideae should include tribes Schrebereae and Myxopyreae. Within the Oleoideae, three monophyletic clades, Schrebera and Fraxinus, Ligustrum and Syringa, and all other genera, were recognized. Nyctanthes, a former member of Verbenaceae nested within a basal paraphyletic assemblege of Jasminoideae. Within the Jasminoideae, Menodora and Jasminum form a strong monophyletic group and share 21 kb chroplast DNA inversion mutation. Abeliophyllum show a sister group relationship with Forsythia rather than Fontanesia.
