Turning gold into 'junk': transposable elements utilize central proteins of cellular networks [PDF]

, 2013
The numerous discovered cases of domesticated transposable element (TE) proteins led to the recognition that TEs are a significant source of evolutionary innovation.

Exonization of the LTR transposable elements in human genome

BMC Genomics, 2007
Background Retrotransposons have been shown to contribute to evolution of both structure and regulation of protein coding genes. It has been postulated that the primary mechanism by which retrotransposons contribute to structural gene evolution is ...

piRNA processing within non‐membrane structures is governed by constituent proteins and their functional motifs

The FEBS Journal, EarlyView.
The silencing of transposable elements is mediated by piRNAs through post‐transcriptional and transcriptional regulation. In Drosophila, piRNAs are processed within unique non‐membrane structures: nuage in germline cells and Yb bodies in somatic gonadal cells.

Gene Deletion in Barley Mediated by LTR-retrotransposon BARE

Scientific Reports, 2017
AbstractA poly-row branched spike (prbs) barley mutant was obtained from soaking a two-rowed barley inflorescence in a solution of maize genomic DNA. Positional cloning and sequencing demonstrated that the prbs mutant resulted from a 28 kb deletion including the inflorescence architecture gene HvRA2.

Hagfish genome reveals parallel evolution of 7SL RNA-derived SINEs

Mobile DNA, 2020
Background Short interspersed elements (SINEs) are ubiquitous components of eukaryotic genomes. SINEs are composite transposable elements that are mobilized by non-long terminal repeat (non-LTR) retrotransposons, also called long interspersed elements ...

Retrotransposons as pathogenicity factors of the plant pathogenic fungus Botrytis cinerea

Genome Biology, 2021
Background Retrotransposons are genetic elements inducing mutations in all domains of life. Despite their detrimental effect, retrotransposons can become temporarily active during epigenetic reprogramming and cellular stress response, which may ...

Evidence for evolution of a new sex chromosome within the haploid‐dominant Marchantiales plant lineage

Journal of Integrative Plant Biology, EarlyView.
Genomic evidence suggests that sex chromosomes may not be conserved within liverworts. Re‐evolution of dioicy in the genus Riccia may have occurred with probable de novo establishment of a new sex chromosome from the autosome, and the m‐chromosomes have evolved independently from chromosomes in the Marchantiales.

Mobile genetic elements – mechanism and consequences of transposition

Journal of Education, Health and Sport, 2017
Retrotransposons represent a significant part of the genome in eukaryote organisms. With DNA transposons, they belong to mobile genetic elements. There are two classes of transposons, DNA transposons and retrotransposons.

Application of iPBS in high-throughput sequencing for the development of retrotransposon-based molecular markers

Current Plant Biology, 2014
Retrotransposons are major components of higher plant genomes, and long terminal repeat (LTR) retrotransposons are especially predominant. Thus, numerous LTR retrotransposon families with high copy numbers exist in most plant genomes.

High‐quality genome of allotetraploid Avena barbata provides insights into the origin and evolution of B subgenome in Avena

Journal of Integrative Plant Biology, EarlyView.
A high‐quality genome sequence of the tetraploid wild oat Avena barbata provides crucial genetic information for the Avena B‐genome, allowing clarification of the evolutionary trajectories of the four subgenomes within Avena and identification of numerous key genes related to environmental adaptability, thus offering valuable resources for oat breeding
