Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

Pitfalls and missing links in current understanding of 4D genomes

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression, maintaining genome stability, and guiding development. The convergence of chromosome conformation capture technologies, super‐resolution microscopy, and single‐cell epigenomics has transformed our understanding of ...

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high‐throughput RNA sequencing

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Optimum recombination rates for genetic gains in simulated recurrent selection in empirical maize populations

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Meiotic recombination creates new allelic combinations, but it also disrupts favorable parental haplotypes. Our objective was to assess if optimum recombination rates exist in elite maize (Zea mays L.) populations undergoing simulated short‐term and long‐term recurrent selection.

Genetic Linkage for Bipolar Disorder to the Distal Region of Chromosome 19q: A Large Family Whole Genome Sequencing Study

Bipolar Disorders, Volume 28, Issue 4, June 2026.
ABSTRACT Background Bipolar disorder (BD) is among the most heritable psychiatric disorders, with a genetic architecture likely consisting of both common genetic variants with small effects and rare variants with strong effects in certain families or populations.
