Structural Characteristics, Comparative Analyses, and Conservation Significance of the Complete Chloroplast Genome of the Critically Endangered <i>Lithocarpus yongfuensis</i> (Fagaceae). [PDF]

Ecol Evol
We assembled and annotated the complete chloroplast genome of L. yongfuensis. The genome structure, gene content, and phylogenetic relationships were analyzed, providing new insights into the species' evolutionary history. These findings offer valuable genomic resources for future studies on taxonomy, conservation, and molecular breeding of L ...

Integrating Morphology and Chloroplast Genomics: A New East Asian Species of <i>Aletris</i> (Nartheciaceae) With Insights Into Regional Phylogeny and Evolution. [PDF]

Ecol Evol
Based on morphological and chloroplast phylogenomic analyses, we describe Aletris medogensis as a new species endemic to the eastern Himalayas. Comparative genomics revealed structural variations, hypervariable markers, and signatures of positive selection in key genes, providing robust evidence for species delimitation and insights into the ...

Genetic diversity of the cultivated Salvia miltiorrhiza populations revealed by four intergenic spacers.

PLoS ONE, 2022
For better understanding the genetic diversity and phylogeny of the cultivated Salvia miltiorrhiza populations, four intergenic spacer sequences, ETS, psbA-trnH, trnL-trnF, and ycf1-rps15 of the 40 populations collected from China were Polymerase Chain ...

Generic status of Winitia (Annonaceae, Miliuseae) reaffirmed by molecular phylogenetic analysis, including a new species and a new combination from Thailand

European Journal of Taxonomy, 2020
The generic status of Winitia Chaowasku (Annonaceae Juss., Miliuseae Hook.f. & Thomson) is reaffirmed by an extensive phylogenetic reconstruction using seven plastome regions (matK, ndhF, rbcL, ycf1 exons; trnL intron; psbA-trnH, trnL-trnF intergenic ...

Phylogeny and Biogeography of Endemic Festuca (Poaceae) from New Zealand Based on Nuclear (ITS) and Chloroplast (trnL–trnF) Nucleotide Sequences [PDF]

, 2007
We investigated the phylogenetic relationships of the endemic New Zealand (NZ) species of Festuca (Poaceae, Pooideae) by assessing sequence variation from the nuclear internal transcribed spacers (ITS) and a chloroplast intergenic spacer (trnL–trnF) and ...

DNA barcoding of the endangered Aquilaria (Thymelaeaceae) and its application in species authentication of agarwood products traded in the market [PDF]

, 2016
The identification of Aquilaria species from their resinous non-wood product, the agarwood, is challenging as conventional techniques alone are unable to ascertain the species origin.

Specimens at the Center: An Informatics Workflow and Toolkit for Specimen-level analysis of Public DNA database data [PDF]

, 2016
Major public DNA databases — NCBI GenBank, the DNA DataBank of Japan (DDBJ), and the European Molecular Biology Laboratory (EMBL) — are invaluable biodiversity libraries. Systematists and other biodiversity scientists commonly mine these databases for
