K. - Molecular phylogenetics of angiosperms: congruent patterns inferred from three genes. Part II.
Combined phylogenetic analyses of gene sequences for 18S ribosomal
RNA, rbcL, and atpB for over 400 species of angiosperms
has yielded a well-resolved framework of angiosperm phylogeny. Many
major clades received strong bootstrap support. The monosulcates form
a grade at the base of the angiosperm tree. The eudicots form a
clade; the lower eudicots include Proteaceae, Nelumbo,
Platanus, Tetracentron, Trochodendron, and the
ranunculids. The two largest clades of higher eudicots are the
Asteridae s.l. and the Rosidae s.l. Smaller clades receiving strong
support include the Caryophyllidae s.l., Saxifragales, Capparales,
Malvales, Cornales, Ericales, and Asteridae s.s. This phylogenetic
framework can contribute to a revised classification of the
angiosperms.
Key words: angiosperm phylogeny, combined analysis, molecular data
