Molecular phylogeny reveals the non-monophyly of tribe Yinshanieae (Brassicaceae) and description of a new tribe, Hillielleae

Plant Diversity, 2016
The taxonomic treatment within the unigeneric tribe Yinshanieae (Brassicaceae) is controversial, owing to differences in generic delimitation applied to its species.

Genetic Characterization of an Endangered Chilean Endemic Species, Prosopis burkartii Muñoz, Reveals its Hybrids Parentage

Plants, 2020
The hybridization of Prosopis burkartii, a critically endangered endemic species, and the identification of its paternal species has not been genetically studied before. In this study we aimed to genetically confirm the origin of this species. To resolve

ITS and trnL-F Sequences analysis of Potentilla discolor Bge. [PDF]

Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015
To provide scientific data of the internal transcribed spacer (ITS) and trnL-F sequences for the authentication of Potentilla discolor Bge., we extracted the genome DNA from the leaves of Potentilla discolor Bge., purchased from Hebei Province, amplified the ITS region using ITS universal primers of angiosperm, and sequenced the purified PCR products ...

Ewangoa, a new threatened Central African genus of Euphorbiaceae‐Acalyphoideae

TAXON, Volume 75, Issue 2, April 2026.
Abstract A new morphologically divergent genus and species of Euphorbiaceae from the Democratic Republic of the Congo, Ewangoa cardiophora, is described and illustrated. This taxon is easily recognised by its leaf‐opposed inflorescences, which are surrounded by a single cordiform involucral bract. Molecular phylogenetic evidence shows that Ewangoa is a

Application of rps16 Intron and trnL-trnF Intergenic Spacer Sequences to Identify Rengas Clone Riau

Biosaintifika: Journal of Biology & Biology Education, 2017
Rengas clone Riau has been identified using morphological characters and molecular technique with a psbA-trnH intergenic spacer, however, this method can only determine its taxonomic status at genus level, namely Gluta sp.  This study reports application
