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

An age-of-allele test of neutrality for transposable element insertions [PDF]
How natural selection acts to limit the proliferation of transposable elements (TEs) in genomes has been of interest to evolutionary biologists for many years.

DNA methylation dynamics during early plant life
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 ...

A new reference genome assembly for the microcrustacean Daphnia pulex [PDF]
Comparing genomes of closely related genotypes from populations with distinct demographic histories can help reveal the impact of effective population size on genome evolution. For this purpose, we present a high quality genome assembly of Daphnia pulex (

Transposable elements in Drosophila
Drosophila has been studied as a biological model for many years and many discoveries in biology rely on this species. Research on transposable elements (TEs) is not an exception.

Hematopoietic (stem) cells—The elixir of life?
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Enrichment analysis of Alu elements with different spatial chromatin proximity in the human genome [PDF]
Transposable elements (TEs) have no longer been totally considered as “junk DNA” for quite a time since the continual discoveries of their multifunctional roles in eukaryote genomes.

Plant transposable elements generate the DNA sequence diversity needed in evolution
Two germinal and 16 somatic reversion events induced by the Enhancer (En) transposable element system at the wx-8::Spm-I8 allele of Zea mays were cloned and studied by sequence analysis. Excision of the Spm-I8 receptor element from the wx gene results in various mutant DNA sequences.
