Phylogenetic relationships of the mycoheterotrophic genus Voyria and the implications for the biogeographic history of Gentianaceae.
TLDR
The results suggest that migration of tropical taxa through Laurasia during the Early Eocene has played an important role in shaping the current global distribution of Gentianaceae.
Large indels obscure phylogeny in analysis of chloroplast DNA (trnL-F) sequence data: Pomaderreae (Rhamnaceae) revisited
TLDR
Phylogenetic analysis of 69 ingroup-taxa of Pomaderreae using trnL-F sequences confirm the monophyly of the tribe and two new genera containing atypical species of Stenanthemum are suggested.
Phylogeny and biogeography of Balsaminaceae inferred from ITS sequences
TLDR
The ITS phylogenies reveal that extant Impatiens species are of Southeast Asian origin, from where dispersals to boreal Eurasia and North America, to central Asia and eastern Europe via the Himalayas, and to India and Africa have occurred.
Evolutionary patterns in neotropical Helieae (Gentianaceae): evidence from morphology, chloroplast and nuclear DNA sequences
TLDR
Parsimony-based phylogenetic analyses of the neotropical tribe Helieae (Gentianaceae) are presented, including 22 of the 23 genera and 60 species, and new pollen and seed characters are evaluated for the first time in a combined morphological-molecular phylogenetic analysis.
Phylogeny and evolution of Burmanniaceae (Dioscoreales) based on nuclear and mitochondrial data.
TLDR
Phylogenetic inference using nucleotide sequences of the nuclear 18S rDNA region and the mitochondrial nad1 b-c intron revealed two well-supported, major lineages within the Burmanniaceae, corresponding to the two tribes recognized in the family: Burmannieae and Thismieae.
Phylogeny of subtribe Gentianinae (Gentianaceae): Biogeographic inferences despite limitations in temporal calibration points
TLDR
The results show that only Metagentiana is polyphyletic and divided into three monophyletic entities, and no unambiguous synapomorphies were associated with the three Met Agentiana entities.
Molecular systematics and biogeography of Crawfurdia, Metagentiana and Tripterospermum (Gentianaceae) based on nuclear ribosomal and plastid DNA sequences.
TLDR
The molecular analyses revealed that Crawfurdia, Metagentiana and Tripterospermum do not merit status as three separate genera, because sampled species of CrawFurdia and Tripterspermum are embedded within Met agentiana.
Phylogenetic patterns and polyploid evolution within the Mediterranean genus Centaurium (Gentianaceae - Chironieae)
TLDR
Phylogenetic relationships, inferred from sequences of both nrDNA and cpDNA regions, confirm the monophyly of Centaurium and reveal the importance of polyploidy within the genus.

The phylogeny of Gentianella (Gentianaceae) and its colonization of the southern hemisphere as revealed by nuclear and chloroplast DNA sequence variation
TLDR
It is postulated that the efimbriate lineage originated in East Asia near the end of the Tertiary and spread via North america to south America, and from there it reached Australia/New Zealand only once by a single long-distance dispersal event.
The phylogenetic relationships and evolution of the Canarian laurel forest endemicIxanthus viscosus (Aiton) Griseb. (Gentianaceae): Evidence frommatK and ITS sequences, and floral morphology and anatomy
TLDR
The phylogenetic relationships found here show that 1) the sister group ofIxanthus is distributed in the Mediterranean area, and that 2) its habit as a basally woody suffrutescent herb is best interpreted as an advanced character state.
Phylogeny of temperate Gentianaceae: A morphological approach
TLDR
The tropical ancestry of the family, the switch from a woody to a herbaceous life form, and the position of critical taxa, such as Swertia and Halenia or Tripterospermum, are discussed.
High paraphyly of Swertia L. (Gentianaceae) in the Gentianella-lineage as revealed by nuclear and chloroplast DNA sequence variation
TLDR
The phylogeny suggested by the analysis of combined data sets defines Swertia as strongly paraphyletic in relation to the other genera, and taxonomic circumscriptions in the Swertiinae sensu Struwe et’al.
Phylogenetic utility of the nuclear rDNA ITS region in subfamilyIxoroideae (Rubiaceae): Comparisons with cpDNArbcL sequence data
TLDR
ITS of the nrDNA were sequenced for 21 taxa inIxoroideae and outgroups (Rubiaceae) and compared with sequences of the cp-generbcL and inconsistencies found may be caused by density of taxon sampling, different evolutionary rates, phylogenetic sorting, homoplasy caused by functional constraints, or sampling of non-orthologous ITS types.
Phylogenetic relationships within the Gentianales based on NDHF and RBCL sequences, with particular reference to the Loganiaceae.
TLDR
Phylogenetic relationships in the Gentianales with focus on Loganiaceae sensu lato are evaluated using parsimony analyses of nucleotide sequence data from the plastid genes rbcL and ndhF, which indicate that the family Rubiaceae forms the sister group to the successively nested Gentianaceae, Apocynaceae, and Logania, all of which are well supported.
A phylogeny of the European gentians inferred from chloroplast trnL (UAA) intron sequences
TLDR
Phylogenetic relationships between the European species of the genus Gentiana L. (Gentianaceae) were inferred from chloroplast trnL (UAA) intron sequence data to suggest a rapid radiation following the colonization of Europe and that cpDNA can violate assumptions of rate constancy at lower taxonomic level.
A trnL-F cpDNA sequence study of the Condamineeae-Rondeletieae-Sipaneeae complex with implications on the phylogeny of the Rubiaceae.
DNA sequences from the chloroplast trnL-F region of 154 Rubiaceae and 11 outgroup taxa were analyzed cladistically. An emphasis was placed on the tribes Rondeletieae, Sipaneeae, and Condamineeae.
Saccifolium (Saccifoliaceae), an endemic of Sierra de la Neblina on the Brazilian-Venezuelan border, is related to a temperate-alpine lineage of Gentianaceae
TLDR
Saccifolium appears to be the sister group of Gentiana and has a basal position in clade E (subtribe Gentianinae Gilg pro parte), a derived clade comprising globally distributed temperate-alpine gentians.
The phylogeny and biogeography of Gentiana L. sect. Ciminalis (Adans.) Dumort.: A historical interpretation of distribution ranges in the European high mountains
TLDR
Differences in infraspecific genetic variation among the widespread species suggest that G. alpina probably experienced more recent dispersal or gene flow than G. angustifolia, and the low number of mutations and the basal position in one clade of the preferred cladogram leads to the conclusion thatG.
