Abstract

Phylogenetic interrelationships in the enlarged order Ericales were investigated by jackknife analysis of a combination of DNA sequences from the plastid genes rbcL, ndhF, atpB, and the mitochondrial genes atp1 and matR. Several well-supported groups were identified, but neither a combination of all gene sequences nor any one alone fully resolved the relationships between all major clades in Ericales. All investigated families except Theaceae were found to be monophyletic. Four families, Marcgraviaceae, Balsaminaceae, Pellicieraceae, and Tetrameristaceae form a monophyletic group that is the sister of the remaining families. On the next higher level, Fouquieriaceae and Polemoniaceae form a clade that is sister to the majority of families that form a group with eight supported clades between which the interrelationships are unresolved: Theaceae-Ternstroemioideae with Ficalhoa, Sladenia, and Pentaphylacaceae; Theaceae-Theoideae; Ebenaceae and Lissocarpaceae; Symplocaceae; Maesaceae, Theophrastaceae, Primulaceae, and Myrsinaceae; Styracaceae and Diapensiaceae; Lecythidaceae and Sapotaceae; Actinidiaceae, Roridulaceae, Sarraceniaceae, Clethraceae, Cyrillaceae, and Ericaceae.

KEYWORDS = Ericales, atpB, atp1, cladistics, DNA,jackknife, Lecythidaceae, matR, ndhF, phylogeny, rbcL.

Additional notes: Lecythidaceae and Sapotaceae are sister with 60% support using the plastid genome (rbcL, ndhF, atpB) but this clade was not recovered with data from the mitochondrial genome (atp1 and MatR) . Barringtonia, Couroupita, and Napoleonaea had 100% support. Morphological support for the Lecythidaceae/Sapotaceae clade is the common occurence of nuclear versus cellular endosperm formation and trilacunar nodes.
