Although polyphyly of Osmanthus has been suggested by different authors, the conclusions of previous studies have lacked robust support due to limited sampling or a paucity of phylogenetic characters. In this study, the phylogeny of Osmanthus was explored using sequences of three informative chloroplast regions (psbJ-petA, rpl32-trnL and rps16-trnQ), including all the five sections of the genus and eight closely related genera. The results confirm that Osmanthus, as presently circumscribed, is… 

Plastid genomes reveal evolutionary shifts in elevational range and flowering time of Osmanthus (Oleaceae)

Comparative genomics and evolutionary analyses on plastomes of 16 of the 28 currently accepted species of Osmanthus showed slow evolutionary pace and low nucleotide variations, all genes being subjected to purifying selection, suggesting that flowering time differentiation is related to the difference in ecological niches.

Molecular characterization of phylogeneticrelationships in Fritillaria species inferred from chloroplast trnL-trnF sequences

The molecular phylogenetic relationships between 10 Fritillaria taxa were presented and analysis revealed the feasibility of the chloroplast trnL-trnF region DNA sequence for phylogeny of the Fritillsaria species.

Complete plastome sequences of Picea asperata and P. crassifolia and comparative analyses with P. abies and P. morrisonicola.

The highly variable regions of the complete plastomes of P. asperata and P. crassifolia are identified as appropriate targets for future use in the phylogenetic reconstructions of closely related, sympatric species of Picea as well as Pinaceae in general.

Museomics illuminate the history of an extinct, paleoendemic plant lineage (Hesperelaea, Oleaceae) known from an 1875 collection from Guadalupe Island, Mexico

It is confirmed that Hesperelaea was a paleoendemic lineage that likely predates Guadalupe Island, and provides a notable example of the high potential of NGS for analyzing historical herbarium specimens and revolutionizing systematics.

Phylogenomic approaches untangle early divergences and complex diversifications of the olive plant family

This study showcases that using multiple sequence datasets (plastid genomes, nuclear SNPs and thousands of nuclear genes) and diverse phylogenomic methods such as data partition, heterogeneous models, quantifying introgression via branch lengths (QuIBL) analysis, and species network analysis can facilitate untangling long and complex evolutionary processes of ancient introgressive, paleopolyploidization, and ILS.

Diversity, ecology and evolution of monocaulous plants in New Caledonia

The convergent evolution in growth habit is a fundamental phenomenon linking plant ecology and evolution. Remarkably illustrated in island biotas, this phenomenon has never been identified in the

Cross-transferability of SSR markers in Osmanthus

The SSR markers described herein will be immediately useful to characterize germplasm, identify hybrids, and aid in understanding the level of genetic diversity and relationships within the cultivated germplasms.



Phylogenetics of Olea (Oleaceae) based on plastid and nuclear ribosomal DNA sequences: tertiary climatic shifts and lineage differentiation times.

This study indicates the necessity of revising current taxonomic boundaries in Olea and suggests that main lines of evolution were promoted by major Tertiary climatic shifts.

Phylogenetic analysis of genus Osmanthus (Oleaceae) based on mat K sequence.

It is thought that comprehensive analysis of matK sequence should be combined with other molecular sequences and morphological indicators in order to obtain scientific and reasonable classification of Osmanthus.

Molecular Phylogeny of Section Parrya of Pinus (Pinaceae) Based on Chloroplast matK Gene Sequence Data

The molecular phylogenetics of sect. Parrya Myre of Pinus L. was analyzed based onchloroplast matKgene sequence data. The section was resolved as paraphyletic because members of thesect. Strobus were

Studies on Cladistic Analysis of Osmanthus

The Osmanthus was cladistically analyzed based on 22 morphological characters and the inter-genetic relationship between Sect.Siphosmanthus and Sect.Linocieroides could not be verified in the article, which should be verified with molecular method.

Cyto-taxonomy and phylogeny of the oleaceae

Although rather easily delimited as a family, the Oleaceae contains a great variety of forms, some of which are stable enough to be easily recognized as species, while others, part icular ly in the genus Fraxinus, are a problem for the taxonomist.

Investigation of this crop's domestication in a phylogeographic study based on the single-copy nuclear gene glyceraldehyde 3-phosphate dehydrogenase demonstrates that single- copy nuclear genes can provide a useful source of informative variation in plants.

Comparison of whole chloroplast genome sequences to choose noncoding regions for phylogenetic studies in angiosperms: the tortoise and the hare III.

Nine newly explored regions of the chloroplast genome offer levels of variation better than the best regions identified in an earlier study and are therefore likely to be the best choices for molecular studies at low taxonomic levels.

Gene relocations within chloroplast genomes of Jasminum and Menodora (Oleaceae) are due to multiple, overlapping inversions.

The chloroplast (cp) DNA sequence of Jasminum nudiflorum (Oleaceae-Jasmineae) is completed and compared with the large single-copy region sequences from 6 related species, finding that their genome organization is surprisingly similar despite the distant relationship of these 2 angiosperm families.

Olea europaea (Oleaceae) phylogeography based on chloroplast DNA polymorphism

A cpDNA phylogenetic tree in which five clades were recognised and located in distinct geographic areas was constructed, suggesting a possible Mediterranean olive origin in an African population, which may have overlapped in the Southern Mediterranean during the Quaternary.
