Abstract The phylogenetic relationships and chromosomal evolution of the diverse tropical genus Passiflora (Passifloraceae) are explored using data from two chloroplast markers: the rpoC1 intron and the trnL/trnT spacer region. A survey of the presence or absence of the rpoC1 intron in 136 species representing 17 of Killip's (1938) 22 subgenera of Passiflora and four other genera in the Passifloraceae revealed intron losses in 46 taxa. A minimum of two losses were confirmed by a parametric… 
Genetic Diversity in Passiflora Species Assessed by Morphological and ITS Sequence Analysis
The results of this study indicate that ITS region analysis represents a useful tool for evaluating genetic diversity in Passiflora at the species level.
Plastome sequences of the subgenus Passiflora reveal highly divergent genes and specific evolutionary features
The findings identified putative candidates, including predicted RNA editing sites and the coding sequences of accD and clpP genes, responsible for nuclear-cytoplasmic incompatibility in the interspecific hybrids of Passiflora.
Phylogeny, biogeography and divergence times in Passiflora (Passifloraceae)
The results indicated that Passiflora ancestors arrived in Central America and diversified quickly from there, with many long distance dispersion events, which seems to follow a biogeographic scenario proposed for several plant groups, originating in Africa, crossing to Europe/Asia and arriving in the New World by way of land bridges.
The role of chromosome changes in the diversification of Passiflora L. (Passifloraceae)
It is suggested that ascending dysploidy provided a great advantage for generating long-term persistent lineages and promoting species diversification, and chromosome numbers/genome size changes may have contributed to morphological/ecological traits that explain the pattern of diversification observed in the genus Passiflora.
The Chloroplast Genome of Passiflora edulis (Passifloraceae) Assembled from Long Sequence Reads: Structural Organization and Phylogenomic Studies in Malpighiales
The results have provided a better understanding of the evolutionary relationships in the Malpighiales and the Fabids, confirming the potential of complete chloroplast genome sequences in inferring evolutionary relationships and the utility of long sequence reads for generating very accurate biological information.
Karyotypic analyses and genomic affinity among Argentinean species of Passiflora
The results obtained strongly suggest that the basic number x = 6 would be the original one and that x = 9 was originated by processes of polyploidsy and descendent dysploidy, which could explain the asymmetrical karyotypes of species of subgenus Passiflora.
Taxonomy and evolutionary relationships of Passiflora subg. Decaloba supersect. Decaloba sect. Xerogona (Passifloraceae): contributions of palynological, morphological and molecular studies
Passiflora subg. Decaloba supersect. Decaloba sect. Xerogona (Passifloraceae) is a tropical and subtropical group comprising 14 species that occur in tropical biomes throughout Latin America,
Molecular phylogenetics of Echinopsis (Cactaceae): Polyphyly at all levels and convergent evolution of pollination modes and growth forms.
A maximum likelihood phylogeny confirms that Echinopsis s.l. is not monophyletic nor are any of the previously recognized genera that have more than one species, and further study of less evolutionary labile traits suitable for circumscribing genera are needed.
A genome sequence resource for the genus Passiflora, the genome of the wild diploid species Passiflora organensis
This study presents the first draft genome assembly of a wild Passiflora species, providing a valuable sequence resource for genomic and evolutionary studies on the genus, and support for breeding cropped passionfruit species.
Molecular phylogenetic analysis of Passifloraceae sensu lato (Malpighiales) based on plastid and nuclear DNA sequences
A phylogenetic analysis of Passifloraceae sensu lato was performed using rbcL, atpB, matK, and 18S rDNA sequences from 25 genera and 42 species, resulting in a single most parsimonious tree, which was very similar to the 50% majority consensus tree from the Bayesian analysis.


Phylogenetic Relationships Among Species of Fragaria (Rosaceae) Inferred from Non-coding Nuclear and Chloroplast DNA Sequences
Abstract Phylogenetic relationships among 43 accessions of Fragaria, representing 14 species, and one accession of the outgroup Potentilla fruticosa, were assessed using nucleotide sequence data from
A first molecular phylogenetic analysis of Passiflora (Passifloraceae).
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.
Ribosomal DNA evolution and phylogeny in Aloe (Asphodelaceae).
Despite the striking stability of karyotype structure and location of 5S r DNA, the distribution of 18S-5.8S-26S rDNA is not so constrained and has clearly changed during Aloe speciation.

Molecular evolution of noncoding regions of the chloroplast genome in the Crassulaceae and related species
Universal primers were used for PCR amplification of three noncoding regions of chloroplast DNA in order to study sequence-length variation in the Crassulaceae and in related species and indicated a pattern of relationships that was largely consistent with a previous analysis of cpDNA restriction-site variation.
Remarks on karyological differentiation patterns in tropical woody plants
Karyomorphology suggests a new systematic arrangement for the Laurales, a new circumscription of theCymbopetalum tribe (Annonaceae), and a placement of theCochlospermaceae/Bixaceae in theViolales.

The distribution of a chloroplast DNA inversion among 80 species representing 16 tribes of the Asteraceae and 10 putatively related families demonstrates the potential of such mutations for resolving phylogenetic relationships at higher taxonomic levels and defines an ancient evolutionary split within the family.
The tortoise and the hare: choosing between noncoding plastome and nuclear Adh sequences for phylogeny reconstruction in a recently diverged plant group.
The relative utility of seven noncoding cpDNA regions and a pair of homoeologous nuclear genes for resolving recent divergences, using tetraploid cottons (Gossypium) as a model system, is tested, with enhanced resolution obtained using the nuclear genes.
Multiple Independent Losses of the rpoC1 Intron in Angiosperm Chloroplast DNA's
Previous studies have shown that in Marchantia, black pine, and the vast majority of angiosperms examined to date, the chloroplast gene rpoCl is interrupted by an intron (of about 750 base pairs),
A Chloroplast DNA Inversion as a Subtribal Character in the Phaseoleae (Leguminosae)
A survey of 50 genera of Phaseoleae and related tribes screened using small chloroplast DNA probes, whose hybridization patterns are diagnostic for the presence or absence of the inversion shows the taxonomic distribution of this inversion is consistent with morpho- logical and other data, and supports recent subtribal classifications.
