Comparative retrotransposon analysis of mutant and non-mutant rice varieties grown at different salt concentrations

Biotechnology & Biotechnological Equipment, 2022
This study investigated the effects of retrotransposon movements on the regeneration of 15- and 30-day-old leaves and roots of four different rice varieties grown in tissue culture medium at different salt concentrations (0, 50, 100, and 200 mmol/L) by ...

ADAR1 restricts LINE-1 retrotransposition [PDF]

, 2016
Adenosine deaminases acting on RNA (ADARs) are involved in RNA editing that converts adenosines to inosines in double-stranded RNAs. ADAR1 was demonstrated to be functional on different viruses exerting either antiviral or proviral effects.

R-loop landscape in mature human sperm: Regulatory and evolutionary implications

Frontiers in Genetics, 2023
R-loops are three-stranded nucleic acid structures consisting of an RNA:DNA hybrid and a displaced DNA strand. While R-loops pose a potential threat to genome integrity, they constitute 5% of the human genome.

LTR-retrotransposons in R. exoculata and other crustaceans [PDF]

, 2013
Transposable elements are major constituents of eukaryote genomes and have a great impact on genome structure and stability. They can contribute to the genetic diversity and evolution of organisms. Knowledge of their distribution among several genomes is

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 ...

FISH mapping and molecular organization of the major repetitive sequences of tomato [PDF]

, 2008
This paper presents a bird's-eye view of the major repeats and chromatin types of tomato. Using fluorescence in-situ hybridization (FISH) with Cot-1, Cot-10 and Cot-100 DNA as probes we mapped repetitive sequences of different complexity on pachytene ...

CRISPR deletion of a SINE-VNTR-Alu (SVA_67) retrotransposon demonstrates its ability to differentially modulate gene expression at the MAPT locus

Frontiers in Neurology, 2023
BackgroundSINE-VNTR-Alu (SVA) retrotransposons are hominid-specific elements which have been shown to play important roles in processes such as chromatin structure remodelling and regulation of gene expression demonstrating that these repetitive elements

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.

Retrotransposon life cycle and its impacts on cellular responses

RNA Biology
Approximately 45% of the human genome is comprised of transposable elements (TEs), also known as mobile genetic elements. However, their biological function remains largely unknown.
