Separated Sexes, Shared Consequences: Disentangling Predictors of Genetic Diversity in Dioecious Angiosperms

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluates the factors influencing intrapopulation genetic diversity in dioecious flowering plants by integrating genetic and ecological data from studies published up to 2025. We show that pollination mode, endemism, and conservation status significantly shape genetic diversity patterns, with endemic and threatened species exhibiting the ...

A linkage map of spring turnip rape based on RFLP and HARD markers

open access: yesAgricultural and Food Science, 1996
A linkage map of spring turnip rape (Brassica rapa ssp. oleifera) was conslructed from an F2 population of a cross Jo4002 x Sv3402. The map contained 22 RFLP loci, 144 RAPDs, one microsatellite, and one morphological marker (seed colour).

DNA polymorphism of schistosomes and their snail hosts

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
Analysis of the genomes of schistosomes and one of their intermediate hosts, Biomphalaria glabrata, using Random Amplified Polymorphic DNA (RAPD) demonstrated that intraspecific genetic polymorphism in the parasite is limited but in the snail is highly ...

Chloroplast Phylogenomics and Barcode Discovery in Medicinal Stachys Species Reveal Evolutionary Relationships and Adaptive Signatures

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study presents the first complete chloroplast genomes of two medicinally important Stachys species, S. persica and S. germanica. Comparative phylogenomic analyses revealed highly conserved genomes with lineage‐specific variations, identified hypervariable regions as candidate DNA barcodes, and detected signatures of positive selection in the petB ...

Tangled Evolutionary History: Genetically Divergent Taxa and Hybrids Characterise Lantana Invasions in Australia

open access: yesEvolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT This study investigated population genomic diversity and structure in the taxonomically complicated and highly invasive Lantana camara L. (Verbenaceae) species complex in Australia. We considered taxonomy, spatial distribution and patterns of morphological and genetic variation in populations across the main invaded area (i.e., coastal and ...

A Machine Learning-Optimized Robot-Assisted Driving System for Efficient Flexible Forming of Composite Curved Components

open access: yesEng
Flexible forming technology breaks through the traditional reliance on rigid molds in the hot-pressing process and demonstrates great potential for fabricating large, lightweight composite components with curved geometries. However, the precise actuation

Genetic diversity of "Pimenta Longa" genotypes (Piper spp., Piperaceae) of the Embrapa Acre germplasm collection

open access: yesGenetics and Molecular Biology, 2004
The commonly known Pimenta longa is a commercially valuable natural resource found wild in Acre, Brazil. Specifically, three Piperaceae species with contested taxonomic status were studied, Piper hispidinervum, Piper aduncum, and Piper hispidum, to ...

A linkage map of spring turnip rape based on RFLP and RAPD markers

open access: yesAgricultural and Food Science, 2008
A linkage map of spring turnip rape (Brassica rapa ssp. oleifera) was constructed from an F2 population of a cross Jo4002 x Sv3402. The map contained 22 RFLP loci, 144 RAPDs, one microsatellite, and one morphological marker (seed colour). All ten B. rapa
