Citrus and Prunuscopia-like retrotransposons

open access: yesTheoretical 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 ...

Molecular polymorphisms that underlie trait variation in crops: Lessons learned from soybean

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Genetic variation within a germplasm is important in crop improvement, providing a foundation for breeders to develop new varieties. Traits of agronomic and economic importance are often mapped to identify the genetic basis of observed phenotypes, oftentimes using quantitative trait locus (QTL) analysis.

MTV sings jubilation for telomere biology in Drosophila

open access: yesFly, 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 ...

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

Pivotal Impacts of Retrotransposon Based Invasive RNAs on Evolution

open access: yesFrontiers 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 ...

A new look at the LTR retrotransposon content of the chicken genome

open access: yesBMC Genomics, 2015
BackgroundLTR retrotransposons contribute approximately 10 % of the mammalian genome, but it has been previously reported that there is a deficit of these elements in the chicken relative to both mammals and other birds.

A Novel Human Cellular System for Studying Normal Aging and for Anti‐Aging Discovery

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
This study introduces a human cellular aging model using placental trophoblasts (hTSC‐STBs) that mimics key aging features like senescence and genomic instability. It aligns with human tissue aging and responds to anti‐aging treatments, offering a scalable platform to screen potential therapies and bridge lab findings to clinical applications ...

A Pan‐TE Map Reveals the Important Role of Transposable Elements in Gene Expression and Phenotypic Diversity in 2,311 Rapeseed Accessions

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
This study presents the first pan‐transposable element (TE) atlas in rapeseed, profiling over 8 million TEs across 2311 accessions. Integrative analyses reveal that TEs broadly shape gene expression through diverse regulatory mechanisms, with key insertions in BnaA03.FLC and BnaA09.CYP78A9 linked to flowering time and silique development.

High‐Quality Genome Assembly of Diplocarpon coronariae Unveils LTR Retrotransposon‐Driven Structural Dynamics in Fungi Evolution

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Long terminal repeat retrotransposons (LTR‐RTs) are recognised as a significant evolutionary force capable of shaping the structure and function of the genomes in eukaryotes, including animals, plants, and fungi. However, much remains largely unknown about how LTR‐RTs influence the evolution of fungi at the chromosomal level.

Retrotransposons and Diabetes Mellitus

open access: yesEpigenomes
Retrotransposons 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.
