DIRS and Ngaro Retrotransposons in Fungi
PLoS ONE, 2013 Retrotransposons with a tyrosine recombinase (YR) have been discovered recently and lack thorough annotation in fungi. YR retrotransposons are divided into 3 groups: DIRS, Ngaro and VIPER (known only from kinetoplastida). We used comparative genomics to investigate the evolutionary patterns of retrotransposons in the fungal kingdom.

The R2 retrotransposon RNA families [PDF]
RNA Biology, 2011 Analysis of the R2 retrotransposons from multiple silkmoth and fruitfly species have revealed three segments that contain conserved RNA secondary structures. These conserved structures play important roles in the propagation of the R2 element, including R2 RNA processing and transposon integration into the host genome as well as a likely role in ...

RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection
Molecular Ecology Resources, EarlyView.ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.

Analysis of Sequence Polymorphism of LINEs and SINEs in Entamoeba histolytica [PDF]
arXiv, 2018 The goal of this dissertation is to study the sequence polymorphism in retrotransposable elements of Entamoeba histolytica. The Quasispecies theory, a concept of equilibrium (stationary), has been used to understand the behaviour of these elements. Two datasets of retrotransposons of Entamoeba histolytica have been used.

Similar Evolutionary Trajectories for Retrotransposon Accumulation in Mammals
bioRxiv, 2017 The factors guiding retrotransposon insertion site preference are not well understood. Different types of retrotransposons share common replication machinery and yet occupy distinct genomic domains.

Retrotransposons and the Eternal Leaves
, 2012 The resurrection plant Craterostigma plantagineum can tolerate up to 96% loss of its relative water content and recover within hours after rehydration. In callus tissue desiccation tolerance is induced by pre-incubation with Abscisic acid (ABA). In callus and plant ABA treatment and dehydration induce a set of dehydration-responsive genes.

Molecular Ecology Resources, EarlyView.ABSTRACT The percomorph fish clade Gobioidei is a suborder that comprises over 2200 species distributed in nearly all aquatic habitats. To understand the genetics underlying their species diversification, we sequenced and annotated the genome of the loach goby, Rhyacichthys aspro, an early‐diverging group, and compared it with nine additional Gobioidei

Retrotransposon Tto1: functional analysis and engineering for insertional mutagenesis [PDF]
, 2011 Retrotransposons are genomic parasites activated by stress conditions that can be seriously detrimental for their host. In this work I demonstrate that Tto1, a typical plant LTR retrotransposon with insertion preference into genes can be turned into a ...

Cell division promotes efficient retrotransposition in a stable L1 reporter cell line [PDF]
, 2013 Background: Long interspersed element type one (L1) actively modifies the human genome by inserting new copies of itself. This process, termed retrotransposition, requires the formation of an L1 ribonucleoprotein (RNP) complex, which must enter the ...

PLoS Comput. Biol., 2017 The AID / APOBEC genes are a family of cytidine deaminases that have evolved in vertebrates, and particularly mammals, to mutate RNA and DNA at distinct preferred nucleotide contexts (or “hotspots”) on foreign genomes such as viruses and retrotransposons.
