BLARER, ALBERT*, DAN NICKRENT, HANS BäNZIGER, PETER K. ENDRESS, AND YIN-LONG QIU. Institute of Systematic Botany, University of Zurich, Zollikerstr. 107, CH-8008 Zurich, Switzerland. - Phylogentic relationsships among genera of the parasitic familiy Rafflesiaceae s.l. based on nuclear ITS and SSU rDNA, mitochondrial LSU and SSU rDNA, atp1, and matR sequences.
We analyzed the sequences of nuclear ITS and SSU rDNA, and
mitochondrial atp1, matR, and LSU and SSU rDNA (total length about
9000 bp) from 13 species and 9 Genera of Rafflesiaceae s.l. Separate
and combined phylogenetic analyses of these six data sets gave
consistent results. They identified four clades that were previously
recognized as Rafflesiaceae s.s., Apodanthaceae, Cytinaceae, and
Mitrastemonaceae. Furthermore, based on expanded unpublished analyses
with other angiosperms, Mitrastemonaceae do not form a monophyletic
group with the other Rafflesiaceae s.l. Bdallophytonforms a
clade with Cytinus.
Key words: atp1, matR, mitochondrial LSU and SSU rDNA, nuclear ITS and SSU rDNA, phylogeny, Rafflesiaceae s.l.
