A Phylogenetic Analysis of the Genus Fragaria (Strawberry) Using Intron-Containing Sequence from the ADH-1 Gene [PDF]
The genus Fragaria encompasses species at ploidy levels ranging from diploid to decaploid. The cultivated strawberry, Fragaria×ananassa, and its two immediate progenitors, F. chiloensis and F. virginiana, are octoploids.

Species concepts and relationships in wild and cultivated potatoes [PDF]
Wild and cultivated potatoes (Solanum section Petota) present challenges to taxonomists arising from lack of clearly defined morphological character differences among many species, phenotypic plasticity, a range of ploidy levels from diploid to hexaploid,

Incongruence between chloroplast and species phylogenies in eucalyptus subgenus monocalyptus (Myrtaceae) [PDF]
Seventy-eight polymorphic cpDNA (chloroplast DNA) characters were found in 13 closely related taxa from Eucalyptus series Amygdalinae (subgenus Monocalyptus) and seven potential outgroup taxa.

Summary Secondary contact between incipient species provides the opportunity to understand how trait divergence restricts gene flow. While mating system transitions are particularly common and involve a suite of phenotypic changes, the extent to which these changes influence gene flow during speciation is poorly understood.

Molecular phylogeny of Muscari (Asparagaceae) inferred from cpDNA sequences
In this study, we tried to figure out phylogenetic relationships and taxonomical positions of closely related Muscari species. Four different cpDNA regions including both coding and non-coding ones, namely, matK, trnT(UGU)-trnL(UAA) intergenic spacer (IGS), trnL(UAA) intron and trnL(UAA)-F(GAA) IGS, were employed to determine the exact circumscription ...

Koenigia bingchachaensis Bo Xu & H. Sun (Polygonaceae), a remarkable new species from the alpine subnival of Zayü County, Xizang, China, is described and illustrated. The integrative evidence from morphology and phylogenetics confirms the status of K. bingchachaensis as a new species, which also highlights the ongoing discovery of unique biodiversity ...

DNA barcoding as a molecular tool to track down mislabeling and food piracy [PDF]
DNA barcoding is a molecular technology that allows the identification of any biological species by amplifying, sequencing and querying the information from genic and/or intergenic standardized target regions belonging to the extranuclear genomes ...

Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Species Identification of Licorice Using nrDNA and cpDNA Genetic Markers
For the accurate identification of medicinal licorice species, nucleotide sequences of four types of DNA regions were researched for 205 specimens, including three species used as licorice: Glycyrrhiza uralensis, Glycyrrhiza glabra, and Glycyrrhiza inflata.
