Technologies for engineering repetitive DNA

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

Detection of Parental Reciprocal Translocations via Inter‐Chromosomal Linkage Disequilibrium in Offspring Genotypes

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Reciprocal translocations (RTs) are among the most common structural chromosomal abnormalities observed in both humans and livestock, characterized by the exchange of DNA segments between two non‐homologous chromosomes and associated with reduced fertility in carriers.

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

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.

Genome Editing in Root and Tuber Crop Development in Sub‐Saharan Africa

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Precision genome editing, particularly using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR‐associated protein 9 (Cas9), is advancing crop improvement by enabling targeted and efficient genetic modifications. Root and tuber crops such as potato, cassava, sweet potato, and yam are vital for global food and nutritional
