A first molecular phylogenetic analysis of Passiflora (Passifloraceae).
TLDR
The results indicate that a reevaluation of the monophyly of Passiflora and its infrageneric classification is necessary, and the relationships among the major clades and of these clades with the related genera remain unresolved. Expand
Molecular phylogeny of the genus Hypochaeris using internal transcribed spacers of nuclear rDNA: inference for chromosomal evolution.
TLDR
The ITS phylogenetic tree suggests that karyotype evolution in Hypochaeris was accompanied with both decreasing and increasing dysploidy, probably with several chromosomal rearrangements, and from an ancestral basic chromosome number of 4 or 5. Expand
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.

Evolution of oil-producing trichomes in Sisyrinchium (Iridaceae): insights from the first comprehensive phylogenetic analysis of the genus.
TLDR
The distribution of oil-flower species across the phylogenetic trees suggests that oil-producing trichomes may have played a key role in the diversification of the genus, a hypothesis that requires future testing. Expand
Phylogenetic analysis of Saccharum s.l. (Poaceae; Andropogoneae), with emphasis on the circumscription of the South American species.
TLDR
Better understanding of the phylogenetic relationships of Saccharum and relatives may be useful for sugarcane breeders to identify potential taxa for interspecific and intergeneric crosses in the genetic improvement of sugarcanes. Expand
Population genetic structure of Sisyrinchium micranthum Cav. (Iridaceae) in Itapuã State Park, Southern Brazil
TLDR
Molecular analysis showed that the populations are highly structured with low gene flow among them, and population genetics in relation to cytogenetic data provided new insights regarding the genetic diversification and mating system of S. micranthum. Expand
Oil-producing flowers within the Iridoideae (Iridaceae): evolutionary trends in the flowers of the New World genera.
TLDR
Floral glandular structures and especially trichomal elaiophores evolved multiple times independently in the American tribes of Iridoideae and the distribution pattern of species displaying glandular trichomes across the phylogeny reveals lability in the pollination system and suggests that these structures may have played a significant role in the diversification of the Iridoidae on the American continent. Expand
Cytogenetic and molecular characterization of morphologically variable Sisyrinchium micranthum (Iridaceae) in southern Brazil
TLDR
Molecular and cytogenetic analyses indicate that some S. micranthum accessions may have more than one ploidy, and all morphological types showed regular meiotic behaviour and high meiotic index values and pollen viability. Expand
Phylogenetic analysis ofIridaceae with parsimony and distance methods using the plastid generps4
TLDR
A molecular phylogeny of the familyIridaceae based on the plastid generps4 was obtained using both parsimony and distance methods, and shows that the family is monophyletic, and that Isophysis is likely to be the earliest emerging genus. Expand
What actually is Vriesea? A total evidence approach in a polyphyletic genus of Tillandsioideae (Bromeliaceae, Poales)
TLDR
A total evidence approach and a more comprehensive Brazilian taxon sampling are used to help circumscribe Vriesea s.s. found in the Chacoan and Parana subregions, providing strong evidence that the genus is not monophyletic as traditionally circumscribed. Expand
