Plant Biology, EarlyView.Cytogenetic quantification of KNL1‐labelled kinetochores in Ornithogalum kochii reveals a significant positive scaling relationship between chromosome size and kinetochore size, demonstrating that chromosome–kinetochore scaling operates even across moderate intra‐karyotype size variation.

Advances in large DNA fragment assembly for microbial cell factory engineering
Quantitative Biology, Volume 14, Issue 3, September 2026.Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

PLoS Genetics, 2012 During meiotic recombination, induced double-strand breaks (DSBs) are processed into crossovers (COs) and non-COs (NCO); the former are required for proper chromosome segregation and fertility.

The Distribution of X-Ray Induced Crossovers from Curly Inversion Heterozygotes of Drosophila melanogaster Females [PDF]
, 1950 That crossing may occur in oogonial cells was suggested by the results of experiments by Whittinghill [1] in which crossing over was induced by x-rays in the X-chromosomes of Drosophila females homozygous for the c3G asynaptic factor.

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.

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

Tackling Plant Meiosis: From Model Research to Crop Improvement
Frontiers in Plant Science, 2018 Genetic engineering and traditional plant breeding, which harnesses the natural genetic variation that arises during meiosis, will have key roles to improve crop varieties and thus deliver Food Security in the future. Meiosis, a specialized cell division

Dynamic reorganization of the genome shapes the recombination landscape in meiotic prophase. [PDF]
, 2019 In meiotic prophase, chromosomes are organized into compacted loop arrays to promote homolog pairing and recombination. Here, we probe the architecture of the mouse spermatocyte genome in early and late meiotic prophase using chromosome conformation ...

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.

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.
