For Nicotiana, with 75 naturally occurring species (40 diploids and 35 allopolyploids), we produced 4656bp of plastid DNA sequence for 87 accessions and various outgroups. The loci sequenced were trnL intron and trnL-F spacer, trnS-G spacer and two genes, ndhF and matK. Parsimony and Bayesian analyses yielded identical relationships for the diploids, and these are consistent with other data, producing the best-supported phylogenetic assessment currently available for the genus.

Nuclear glutamine synthetase evolution in Nicotiana: phylogenetics and the origins of allotetraploid and homoploid (diploid) hybrids.
TLDR
Results were particularly useful for determining the paternal lineage of previously enigmatic taxa (for which previous analyses had revealed only the maternal progenitors), and shed light on the origins of the two oldest and largest allotetraploid sections of Nicotiana.
Long-term genome diploidization in allopolyploid Nicotiana section Repandae (Solanaceae).
TLDR
Sequence analysis indicates that 35S and 5S units most closely resemble maternal and paternal progenitors, respectively, in recent Nicotiana allopolyploid section Repandae.
RECONSTRUCTING THE COMPLEX EVOLUTIONARY ORIGIN OF WILD ALLOPOLYPLOID TOBACCOS (NICOTIANA SECTION SUAVEOLENTES)
TLDR
Nicotiana exemplifies many of the factors that can complicate the reconstruction of polyploid evolutionary history and highlights how reticulate evolution at the diploid level can add even greater complexity to allopolyploid genomes.
Comparative genomics and repetitive sequence divergence in the species of diploid Nicotiana section Alatae.
TLDR
This work reconstructs the history of karyotype and tandem repeat evolution in species of diploid Nicotiana section Alatae and suggests that sequence homogenization has replaced HRS60 family repeats at sub-telomeric regions, but that this process may not occur, or occurs more slowly, when the repeats are found at intercalary locations.
Extensive plastid-nuclear discordance in a recent radiation of Nicotiana section Suaveolentes (Solanaceae)
TLDR
Initial results portray Nicotiana section Suaveolentes as experiencing recent and ongoing radiation in the arid zone of Australia, with strong morphological differentiation between most of the core Australian taxa and obvious differences in ecological preferences.
Molecular phylogeny of tribe Forsythieae (Oleaceae) based on nuclear ribosomal DNA internal transcribed spacers and plastid DNA trnL-F and matK gene sequences
TLDR
Combined sequence data strongly supported the monophyly of Forsythieae and the close relationship between Fontanesia and Jasminum and three Forsythia lineages were suggested.
Molecular phylogenetics of Ruscaceae sensu lato and related families (Asparagales) based on plastid and nuclear DNA sequences.
TLDR
The combination of the three genes results in the most highly resolved and strongly supported topology yet obtained for Asparagales including Ruscaceae s.l. and related groups, and Parsimony bootstrap analysis was performed to assess support of clades.
Parental origin of the allotetraploid tobacco Nicotiana benthamiana
TLDR
The results underscore the usefulness of phylome analysis for subgenome characterization in hybrid species and demonstrate that the advanced stage of long‐term genome diploidization in N. benthamiana is reflected in its subgenomes.
A molecular phylogeny of the Solanaceae
TLDR
The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive "x = 12" clade, which includes Nicotiana and the Australian tribe Anthocercideae, and provide greater resolution among lineages within Solanoidesae.
Repetitive DNA Dynamics and Polyploidization in the Genus Nicotiana (Solanaceae)
TLDR
The lag-phase hypothesis, which describes post-polyploid radiations, is posed as a potentially important mechanism of evolution in Nicotiana section Suaveolentes, the largest polyploid section that consists of over half the current species diversity.

Molecular phylogeny of Nicotiana (Solanaceae) based on the nucleotide sequence of the matK gene.
TLDR
The results support the previous hypothesis that this genus originated in South America and subsequently spread to other continents and the suggestion that the ancestral basic chromosome number is x = 12 and that polyploidsy and aneuploidy have occurred independently several times during the evolution of Nicotiana species is discussed.
Molecular systematics, GISH and the origin of hybrid taxa in Nicotiana (Solanaceae).
TLDR
Relying solely upon ITS nrDNA analysis to reveal phylogenetic patterns in a complex genus such as Nicotiana is insufficient, and it is clear that conventional analysis of single data sets, such as ITS, is likely to be misleading in at least some respects about evolutionary history.
Phylogenetic relationships in Solanum (Solanaceae) based on ndhF sequences
TLDR
Several prominent morphological characters such as spines, stellate hairs, and tapered anthers apparently have evolved more than once in Solanum.
Phylogeny and biogeography of the genus Lycium (Solanaceae): inferences from chloroplast DNA sequences.
TLDR
To investigate phylogenetic and biogeographic relationships of the genus with emphasis on L. sandwicense, the coding region of matK, the two intergenic spacers trnT (UGU)-trnL (UAA) and trnF (GAA), and the trnL intron of chloroplast DNA (cpDNA) were sequenced.
Phylogenetics of Tribe Anthocercideae (Solanaceae) Based on ndhF and trnL/F Sequence Data
TLDR
The phylogeny was used to test the tribe's monophyly, discover relationships within the tribe, and make inferences on character evolution and biogeography, and several characters were inferred to be derived within the Anthocercideae.
An unusual ribosomal DNA sequence from Gossypium gossypioides reveals ancient, cryptic, intergenomic introgression.
TLDR
An example of cryptic, intergenomic introgression between species groups now occupying different hemispheres illustrates how ITS data may provide insights into genome composition and evolutionary history, especially when used in the context of a holistic view that encompasses information from a variety of sources.
Molecular systematics of Iridaceae: evidence from four plastid DNA regions.
TLDR
In the combined tree, all subfamilies were resolved as monophyletic, except Nivenioidae that formed a grade in which Ixioideae were embedded, and this subfamily also lacks clear morphological synapomorphies and is highly heterogeneous, so it is difficult to develop a strong case on nonmolecular grounds for their monophyly.
A phylogenetic analysis of Rhamnaceae using rbcL and trnL-F plastid DNA sequences.
TLDR
The plastid trees support the monophyly of the Rhamnaceae family and provide the basis for a new tribal classification, and three strongly supported clades are identified but morphological characters could not be found to underpin a formal taxonomic description of these three clades as subfamilies.
Molecular cytogenetic analyses and phylogenetic studies in the Nicotiana section Tomentosae
TLDR
It is predicted that the GRD classes of sequence integrated into an ancestral genome only once in the evolution of section Tomentosae and thereafter spread by vertical transmission and speciation into four species.
Combining Data in Phylogenetic Systematics: An Empirical Approach Using Three Molecular Data Sets in the Solanaceae
TLDR
Data from sequences of two chloroplast DNA genes, ndhV and rbcL, and from restriction site mapping studies of the entire chloroplane genome were analyzed for the same set of 17 species of Solanaceae and the outgroup Ipomoea, finding the "X = 12" dade is the most well-supported dade within the family.
