Species Identification of Licorice Using nrDNA and cpDNA Genetic Markers

open access: yesBiological and Pharmaceutical Bulletin, 2007
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.

Less pollen-mediated gene flow for more signatures of glacial lineages: congruent evidence from balsam fir cpDNA and mtDNA for multiple refugia in eastern and central North America.

open access: yesPLoS ONE, 2015
The phylogeographic structure and postglacial history of balsam fir (Abies balsamea), a transcontinental North American boreal conifer, was inferred using mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA) markers.

Temporal stability and spatial patterns of genetic diversity in populations of the climate‐vulnerable fucoid Scytothalia dorycarpa

open access: yesJournal of Phycology, EarlyView.
Abstract Climate change is driving the loss of genetic diversity, potentially limiting species' capacity to adapt to environmental change. Detecting changes in genetic diversity requires replicated temporal data, which is lacking for most species. Here, we combined contemporary and historical specimens of the climate‐vulnerable fucoid Scytothalia ...

Comparison of Auxenochlorella protothecoides and Chlorella spp. Chloroplast Genomes: Evidence for Endosymbiosis and Horizontal Virus-like Gene Transfer

open access: yesLife, 2022
Resequencing of the chloroplast genome (cpDNA) of Auxenochlorella protothecoides UTEX 25 was completed (GenBank Accession no. KC631634.1), revealing a genome size of 84,576 base pairs and 30.8% GC content, consistent with features reported for the ...

Understanding the evolution of native pinewoods in Scotland will benefit their future management and conservation [PDF]

open access: yes, 2010
Scots pine (Pinus sylvestris L.) is a foundation species in Scottish highland forests and a national icon. Due to heavy exploitation, the current native pinewood coverage represents a small fraction of the postglacial maximum.

Introgression despite minimal hybridization: mating system modulates phenotypic associations with introgression in Clarkia

open access: yesNew Phytologist, EarlyView.
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.

A Phylogenetic Analysis of the Genus Fragaria (Strawberry) Using Intron-Containing Sequence from the ADH-1 Gene [PDF]

open access: yes, 2014
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.
