Short-term mutagenicity test by using IRAP molecular marker in rice grown under herbicide treatment

Biotechnology & Biotechnological Equipment, 2018
Rice is an economically important plant as well as a model organism. The rice genome consists of 35% retrotransposons. Although most of the retrotransposons are inactivated through evolutionary processes, they can be activated under various biotic and ...

An Endogenous Retrovirus from Human Hookworm Encodes an Ancient Phlebovirus-Like Class II Envelope Fusion Protein

Proceedings, 2020
Within the parasitic nematode Ancylostoma ceylanicum, a ~20 million-year-old Bel/Pao LTR retrotransposon encodes an ancient viral class II envelope fusion protein termed Atlas Gc.

Extracellular vesicles mediate the horizontal transfer of an active LINE-1 retrotransposon

Journal of Extracellular Vesicles, 2019
Long interspersed element-1 (LINE-1 or L1) retrotransposons replicate through a copy-and-paste mechanism using an RNA intermediate. However, little is known about the physical transmission of retrotransposon RNA between cells.

Mobilization of LINE-1 retrotransposons is restricted by Tex19.1 in mouse embryonic stem cells

eLife, 2017
Mobilization of retrotransposons to new genomic locations is a significant driver of mammalian genome evolution, but these mutagenic events can also cause genetic disorders.

The use of retrotransposon-based molecular markers to analyze genetic diversity [PDF]

Ratarstvo i Povrtarstvo, 2011
Molecular markers play an essential role in all aspects of genetics, modern plant breeding, in human forensics, for map-based cloning of genes, ranging from the identification of genes responsible for the desired traits to the management of backcrossing ...

Retrotransposon insertions can initiate colorectal cancer and are associated with poor survival

Nature Communications, 2018
Genomic instability pathways in colorectal cancer (CRC) have been extensively studied, but the role of retrotransposition in colorectal carcinogenesis remains poorly understood.

The Genomic Shock Hypothesis: Genetic and Epigenetic Alterations of Transposable Elements after Interspecific Hybridization in Plants

Epigenomes, 2023
Transposable elements (TEs) are major components of plant genomes with the ability to change their position in the genome or to create new copies of themselves in other positions in the genome.

TUT-TUTting retrotransposons [PDF]

Nature Reviews Molecular Cell Biology, 2018
3′uridylation by TUT4 and TUT7 is shown as a post-transcriptional mechanism restricting retrotransposition of LINE-1 elements and also replication of animal RNA viruses.

Function of a retrotransposon nucleocapsid protein [PDF]

RNA Biology, 2010
Long terminal repeat (LTR) retrotransposons are not only the ancient predecessors of retroviruses, but they constitute significant fractions of the genomes of many eukaryotic species. Studies of their structure and function are motivated by opportunities to gain insight into common functions of retroviruses and retrotransposons, diverse mechanisms of ...
