Hypermethylated LTR retrotransposon exhibits enhancer activity
Epigenetics, 2017 LTR retrotransposons are repetitive DNA elements comprising ∼10% of the human genome. They are silenced by hypermethylation of cytosines in CpG dinucleotides and are considered parasitic DNA serving no useful function for the host genome.

Citrus and Prunuscopia-like retrotransposons
Theoretical and Applied Genetics, 1999 Many of the world's most important citrus cultivars ("Washington Navel", satsumas, clementines) have arisen through somatic mutation. This phenomenon occurs fairly often in the various species and varieties of the genus.The presence of copia-like retrotransposons has been investigated in fruit trees, especially citrus, by using a PCR assay designed to ...

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.

MTV sings jubilation for telomere biology in Drosophila
Fly, 2018 Telomere protects the ends of linear chromosomes. Telomere dysfunction fuels genome instability that can lead to diseases such as cancer. For over 30 years, Drosophila has fascinated the field as the only major model organism that does not rely on the ...

The Plant Genome, Volume 19, Issue 2, June 2026.Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.

Pivotal Impacts of Retrotransposon Based Invasive RNAs on Evolution
Frontiers in Microbiology, 2017 RNAs have long been described as the mediators of gene expression; they play a vital role in the structure and function of cellular complexes. Although the role of RNAs in the prokaryotes is mainly confined to these basic functions, the effects of these ...

Insect Molecular Biology, Volume 35, Issue 3, Page 232-245, June 2026.Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

Journal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Retrotransposons and Diabetes Mellitus
EpigenomesRetrotransposons are invasive genetic elements, which replicate by copying and pasting themselves throughout the genome in a process called retrotransposition. The most abundant retrotransposons by number in the human genome are Alu and LINE-1 elements, which comprise approximately 40% of the human genome.
