Chloroplast DNA sequence of the green alga Oedogonium cardiacum (Chlorophyceae): Unique genome architecture, derived characters shared with the Chaetophorales and novel genes acquired through horizontal transfer [PDF]

open access: yes, 2008
Background To gain insight into the branching order of the five main lineages currently recognized in the green algal class Chlorophyceae and to expand our understanding of chloroplast genome evolution, we have undertaken the sequencing of chloroplast ...

Sedum diversiflorum sp. nov. (Crassulaceae), a new species with variable merosity from the Satsunan Islands, Kagoshima, Japan

open access: yesNordic Journal of Botany, Volume 2025, Issue 12, December 2025.
We re‐examined the taxonomic status of a plant previously identified as Sedum formosanum subsp. formosanum from four islands in the Satsunan Islands, Japan. To clarify its taxonomic identity, we conducted morphological and phenological comparisons and performed molecular phylogenetic analyses based on nuclear internal transcribed spacer (ITS) and three

Patterns of cpDNA diversity within a beech refugial area

open access: yes, 2013
This study aims at the description of beech postglacial movement within a mountain. The selected mountain Paggeo is isolated, while beech forms an altitudinal continuum for more than 1000m. Previous genetic studies have indicated the possible presence of a glacial refugium in the broader region.

Cryptic Repeated Genomic Recombination During Speciation in Gossypium gossypioides [PDF]

open access: yes, 2003
The Mexican cotton Gossypium gossypioides is a perplexing entity, with conflicting morphological, cytogenetic, and molecular evidence of its phylogenetic affinity to other American cottons.

Genetic Assignment at Different Geographical Levels: A Case Study in a Forest Tree Species (Pinus pinaster Ait.) Using SNP Markers

open access: yesEvolutionary Applications, Volume 18, Issue 12, December 2025.
ABSTRACT Genetic markers can assist in the identification of the stock origin in different organisms. Comparative studies of forest tree provenances have demonstrated that forest tree populations differ in performance across environments and at multiple geographic levels: populations nested within regions nested within gene pools.

CpDNA-based species identification and phylogeography: application to a complex of African tropical tree species [PDF]

open access: yes, 2010
Despite their importance as a hotspot of biodiversity, the history of the African tropical lowland rainforests is poorly known. In particular the respective influence of past climatic factors, environmental heterogeneity and physical barriers on the ...

Tracking a genetic signal of extinction-recolonization events in a neotropical tree species: Voucapoua americana Aublet in French Guiana [PDF]

open access: yes, 2003
Drier periods from the late Pleistocene and early Holocene have been hypothesized to have caused the disappearance of various rainforest species over large geographical areas in South America and restricted the extant populations to mesic sites ...

Evolutionary History and Rhizosphere Microbial Community Composition in Domesticated Hops (Humulus lupulus L.)

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Humulus lupulus L., commonly known as hop, is a perennial crop grown worldwide and is well known for its pharmacological, commercial, and most importantly brewing applications. For hundreds of years, hop has undergone intense artificial selection, with over 250 cultivated varieties being developed worldwide, all displaying differences in key ...

Distribution of deletion type in cpDNA of cultivated and wild rice.

open access: yesThe Japanese Journal of Genetics, 1993
The ORF100 region within Pst-12 fragment of chloroplast DNA (cpDNA) in rice (Oryza sativa) were amplified by polymerase chain reaction in 137 cultivars and 117 strains of wild rice from various countries. Two cpDNA types, with and without a deletion at the region, were found. In O.

THE HETEROPLASMIC AND HOMOPLASMIC STATES OF MITOCHONDRIAL AND CHLOROPLAST DNA REGIONS IN THE PROGENIES OF WIDE HYBRIDS OF COMMON WHEAT OF DIFFERENT ORIGINS

open access: yesВавиловский журнал генетики и селекции, 2014
The states of the 18S/5S mitochondrial (mt) repeat and some chloroplast DNA regions have been studied in alloplasmic lines of common wheat with cytoplasm from barley species Hordeum marinum subsp. gussoneanum Hudson and H. vulgare L., and in progenies of
