IDENTIFICATION OF LENS CULTIVARS IN MARKET BY MOLECULAR TOOLS: DNA BARCODING AND SSRs

open access: yesTrakya University Journal of Natural Sciences, 2023
Substitution of plant cultivars of high commercial value with a cheaper, lower quality one is a common fraud committed against consumers and producers. Since it is one of the most widely grown legumes, lentil (Lens culinaris Medik.) is suitable for such ...

Identification of three kinds of Plumeria flowers by DNA barcoding and HPLC specific chromatogram

open access: yesJournal of Pharmaceutical Analysis, 2018
DNA barcoding and HPLC specific chromatogram were used to identify three kinds of Plumeria flowers respectively. DNAs extracted from the three Plumeria species were amplified by PCR with universal primers, and the psbA-trnH region was selected.

Molecular phylogenetics of Fissistigma Griffith(Annonaceae) [PDF]

open access: yes, 2016
瓜馥木属FissistigmaGriffith隶属于番荔枝科(Annonaceae),全世界约有50多种,广泛分布于亚洲的热带和亚热带地区。该属虽然种数不多,但缺乏专门分类学修订,存在不少分类问题,至今仍没有属下分类系统。本研究利用分子系统学的实验方法,结合标本研究,对瓜馥木属内26种植物的种间关系进行了探讨,对个别种进行分类学处理,为该属后续研究提供基础资料。 本研究对26种瓜馥木属植物叶绿体DNA片段进行了DNA提取、扩增和序列测定(包括cpDNA的rbcL、matK、trnL-trnF以及psbA-

Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

An In Silico Approach for Evaluation of ITS, rbcL, and psbA-trnH for DNA Barcoding of Eugenia spp.

open access: yesBiosfer: Jurnal Tadris Biologi
The genus Eugenia is known to be complex with intricate synonyms and taxonomy, and morphological identification is often unreliable due to overlapping characteristics and environmental influences, particularly in the flowers.

A similar phylogeographical structure among sympatric North American birches (Betula) is better explained by introgression than by shared biogeographical history [PDF]

open access: yes, 2014
AimA comparative analysis of the chloroplast (cp) DNA structure of eastern North American birches (Betula) was undertaken to infer the impacts of Quaternary climate change on the phylogeographical structure of these species.LocationEastern North America ...

Unraveling cryptic lineages in Jatropha nana: phylogenetic evidence supports species status for J. benghalensis (Euphorbiaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The taxonomic framework of the genus Jatropha (Euphorbiaceae) is well established, but its geophytic species present significant classification challenges. These difficulties arise from species complexes, cryptic traits, and high environmental and phenotypic variability.

Molecular Phylogenetic Studies of Korean Calystegia R.Br. Based on ITS and psbA-trnH Sequences

open access: yesKorean Journal of Plant Taxonomy, 2011
Molecular phylogenetic studies were conducted to evaluate evolutionary trends, relationships and species identities among four species, one variety and one outgroup of the Korean Genus Calystegia. The important characteristics of Calystegia are the shape of the lamina, the length ofthe corolla and the presence of hair.
