LEE, HAE-LIM* AND KI-JOONG KIM. Department of Biology, Yeungnam University, Kyeungsan, Kyeungbuk, Korea 712-742. - Intergeneric relationships of Oleaceae based on cpDNA noncoding sequences and nuclear ITS sequences.
Phylogenetic relationships among all genera of Oleaceae were
reconstructed based on the three noncoding region sequences of
chloroplast genome and ITS sequences of nuclear rDNA. The phylogeny
based on the noncoding region of chloroplast genome show congruent
topology to the phylogeny based on the coding sequences of ndhF
and rbcL. The ITS phylogeny also show conguent topology to that
of chloroplast genome. Several taxa have more than two copies of ITS
sequences. Both data support the paraphyly of subfamily
Jasminoideae and monophyly of subfamily Oleoideae.
Several uncertain alignments of sequences are encountered in the
Jasminoideae both ITS and noncoding chloroplast sequences,
however, the alignment within the Oleoideae was
straightforward. The nonconding region data show better resolution
than that of the coding region data in the subfamily Oleoideae.
Within the Oleoideae, four major clades were recognized
including Schrebera-Fraxinus, Forestiera-Priogymnanthus,
Ligustrum-Syringa, and all other members of the tribe
Oleeae. Several paraphyletic genera were recognized within the
tribe Oleeae.
