Endemic but not eroded: Genomic distinctiveness and conservation genomics of the British swallowtail butterfly (Papilio machaon britannicus)

open access: yesInsect Conservation and Diversity, Volume 19, Issue 5, Page 1260-1274, September 2026.
Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.

Comparison of RAPDs, AFLPs and SSR markers for the genetic analysis of yeast strains of Saccharomyces cerevisiae

open access: yes, 2005
We evaluated the usefulness of different molecular techniques for the genetic analysis of Saccharomyces cerevisiae strains. Three commonly used PCR-derived genetic methods, random amplified polymorphic DNA (RAPDs), amplified fragment length polymorphism (

BcMFSR Is Required for Efficient Uptake of Exogenous dsRNA and Spray‐Induced Gene Silencing in Botrytis cinerea

open access: yesMolecular Plant Pathology, Volume 27, Issue 9, September 2026.
Spray‐induced gene silencing (SIGS) uses exogenous dsRNA to silence pathogen genes and control grey mould disease. We identify BcMFSR, an MFS protein required for dsRNA uptake and SIGS efficacy in Botrytis cinerea. Loss of BcMFSR abolishes dsRNA internalization and disease suppression, revealing a novel role for MFS proteins.

Twenty‐Year Progress in Landscape Genetics of Tetrapods

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Geographic distribution of tetrapod landscape genetics between 2003 and 2025. ABSTRACT Landscape genetics, an interdisciplinary field integrating population genetics, landscape ecology, and spatial analytical techniques, has progressed significantly over two decades, yet systematic reviews of its application to tetrapods remain limited. Here, we review

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 ...

Metabolite Variations in Lepidium sativum Seeds Among Different Germplasms: Unraveling the Link Between Environment and Chemical Compounds

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Comparative phytochemical analysis of Lepidium sativum seed populations revealed environmentally driven variation in essential oil composition, while fatty acid profiles remained largely stable across populations. Benzyl nitrile was the dominant essential oil constituent, α‐linolenic acid was the major fatty acid, and all populations exhibited weak ...

Genetic diversity and population structure of Ascochyta rabiei from the western Iranian Ilam and Kermanshah provinces using MAT and SSR markers [PDF]

open access: yes, 2010
Knowledge of genetic diversity in A. rabiei provides different levels of information that are important in the management of crop germplasm resources. Gene flow on a regional level indicates a significant potential risk for the regional spread of novel ...

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).
