The DNA sequence of the transposable element Ac of Zea mays L. [PDF]

Molecular and General Genetics MGG, 1984
The sequence of the Ac element isolated from the wx-m7 allele has been determined. The Ac element is 4563 bp long. A central portion of roughly 3.1 kb is occupied by three open reading frames, two of which point in one direction and the third in the opposite direction.

The Dynamic Interplay Between Ribosomal DNA and Transposable Elements: A Perspective From Genomics and Cytogenetics

Molecular biology and evolution
Although both are salient features of genomes, at first glance ribosomal DNAs and transposable elements are genetic elements with not much in common: whereas ribosomal DNAs are mainly viewed as housekeeping genes that uphold all prime genome functions ...

Horizontal transfer and evolution of transposable elements in vertebrates

Nature Communications, 2020
Horizontal transfer of transposable elements (HTT) is an important process shaping eukaryote genomes, yet very few studies have quantified this phenomenon on a large scale or have evaluated the selective constraints acting on transposable elements (TEs ...

Copy number-dependent DNA methylation of the Pyricularia oryzae MAGGY retrotransposon is triggered by DNA damage

Communications Biology, 2021
Ba Van Vu, Quyet Nguyen et al. investigate the mechanism by which transposable elements are targeted for DNA methylation, using the fungus Pyricularia oryzae as a model system.

Occurrence of LINE, gypsy-like, and copia-like retrotransposons in the clonally propagated sweet potato (Ipomoea batatas L.) [PDF]

, 2011
Retrotransposons are a class of transposable elements that represent a major fraction of the repetitive DNA of most eukaryotes. Their abundance stems from their expansive replication strategies.

Shedding light on DNA methylation and its clinical implications: the impact of long-read-based nanopore technology

Epigenetics & Chromatin
DNA methylation is an essential epigenetic mechanism for regulation of gene expression, through which many physiological (X-chromosome inactivation, genetic imprinting, chromatin structure and miRNA regulation, genome defense, silencing of transposable ...

DNA methylation dynamics during early plant life

Genome Biology, 2017
Background Cytosine methylation is crucial for gene regulation and silencing of transposable elements in mammals and plants. While this epigenetic mark is extensively reprogrammed in the germline and early embryos of mammals, the extent to which DNA ...

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Loss of the DNA methyltransferase MET1 Induces H3K9 hypermethylation at PcG target genes and redistribution of H3K27 trimethylation to transposons in Arabidopsis thaliana. [PDF]

, 2012
Dimethylation of histone H3 lysine 9 (H3K9m2) and trimethylation of histone H3 lysine 27 (H3K27m3) are two hallmarks of transcriptional repression in many organisms.
