Multilocus microsatellite typing (MLMT) reveals high genetic diversity of Leishmania infantum strains causing tegumentary leishmaniasis in northern Italy

This study utilizes multilocus microsatellite typing to reveal high genetic diversity among *Leishmania infantum* strains causing tegumentary leishmaniasis in northern Italy, identifying a distinct parasite population exclusive to skin infections that underscores the necessity of integrated One Health surveillance to understand the disease's epidemiology.

ABCG transporter knockouts alter integument and eye pigmentation with gene-specific effects on viability in butterflies and moths

This study utilizes CRISPR-Cas9 to demonstrate that ABCG transporters (white, scarlet, and oily kinshiryu) play conserved, tissue-specific roles in regulating ommochrome and uric acid deposition for integument and eye pigmentation across diverse Lepidoptera, while also revealing gene-specific viability effects that make scarlet mutants a practical tool for future genetic research.

Enhancing Detection of Polygenic Adaptation: A Comparative Study of Machine Learning and Statistical Approaches Using Simulated Evolve-and-Resequence Data

This study demonstrates that a hybrid approach combining One-Class Support Vector Machines with Fisher's Exact Test outperforms traditional statistical and standalone machine learning methods in detecting polygenic adaptation from simulated evolve-and-resequence time-series data, particularly during the late dynamic phase of selection.

Synthetic analogue of adrenocorticotropic hormone, ACTH(4-7)PGP delays neurological manifestations in diseases of mucopolysaccharidosis III spectrum by reducing neuroinflammation and rescuing neurotransmission, synaptogenesis, and axonal demyelination

This study demonstrates that intranasal administration of the synthetic peptide ACTH(4-7)PGP effectively delays neurological progression and extends lifespan in mouse models of Mucopolysaccharidosis III by reducing neuroinflammation, rescuing synaptic transmission and myelination, and improving cognitive and behavioral deficits without adverse effects.

Explaining the unexplained admixture mapping signals via rare variants: the HCHS/SOL

Using whole-genome sequencing and metabolomics data from the HCHS/SOL study, this research demonstrates that while rare variants show replicated associations with metabolite levels, expanding the genomic search region for common variants, rather than including rare variants, is the primary factor explaining previously unexplained admixture mapping signals.

(Epi-)Genomic Data in the German TwinLife Study: TwinSNPs and TECS Cohort Profiles

This cohort profile describes the curation and initial analyses of molecular genetic and epigenetic data from the TwinSNPs and TECS satellite projects within the German TwinLife study, highlighting the high correlation of epigenetic clocks with age, the predictive value of polygenic scores for sample retention, and the potential of combining (epi)genomic data with within-family designs to advance research on social inequalities.

Introgression from the wild relative Manihot glaziovii on cassava (M. esculenta) chromosome 1 exhibits segregation distortion and no direct effect on dry matter

This study demonstrates that the large *Manihot glaziovii* introgression on cassava chromosome 1 does not directly confer the previously attributed dry matter benefits but instead exhibits segregation distortion and deleterious effects on vigor, suggesting that recombination and purging of this region are necessary for cassava improvement.

Landrace and bred accessions of allotetraploid sour cherry (Prunus cerasus L.) reveal variation in subgenome dosage and subgenome expression bias

This study reveals that diverse sour cherry accessions exhibit significant variation in subgenome dosage through homoeologous exchanges and replacements, alongside dynamic expression biases favoring the *P. fruticosa*-derived subgenomes over the *P. avium*-derived subgenome, which collectively influence key breeding traits like fruit softening.

Exploring the genetic architecture underlying dietary fiber content in Colombian Andean blueberry (Vaccinium meridionale Swartz)

This study integrates extensive phenotyping with genome-wide association analysis in Colombian Andean blueberry (Vaccinium meridionale) to identify 24 QTLs and specific candidate genes, such as glycosyltransferases and pectin methylesterases, that govern the polygenic architecture of dietary fiber content and composition, thereby providing molecular targets for breeding improved nutritional and processing traits.
