Yeast retrotransposons and tRNAs
Trends in Genetics, 1993The role of tRNAs in protein synthesis seems routine when compared with the novel ways in which the Ty retrotransposons of Saccharomyces cerevisiae use these interpreters of the genetic code. tRNAs and tRNA genes control essential steps in the retrotransposon life cycle by regulating protein expression, priming DNA synthesis and specifying integration ...

Retrotransposon families in rice
Molecular and General Genetics MGG, 1992Three families of retrotransposons of rice (Tos1, Tos2, and Tos3) were isolated by using a method based on the sequence conservation of the primer binding site for reverse transcription. This method should be generally applicable for cloning retrotransposon of other plants. One retrotransposon, Tos3-1, was studied in detail.

LTR retrotransposons in plants [PDF]
Russian Journal of Genetics: Applied Research, 2011 Ty1/copia and Ty3/gypsy LTR retrotransposons represent a significant part of plant genomes and play an important role in their structure, functioning, and evolution. The majority of information about this group of transposable elements is related to agricultural plant species and model objects, such as Arabidopsis thaliana. The most investigated groups

True Homoplasy of Retrotransposon Insertions in Primates
Systematic Biology, 2018How reliable are the presence/absence insertion patterns of the supposedly homoplasy‐free retrotransposons, which were randomly inserted in the quasi infinite genomic space? To systematically examine this question in an up‐to‐date, multigenome comparison,

Retrotransposons and regulatory suites
BioEssays, 2005Cellular differentiation and multicellular development require the programmed expression of coregulated suites of genetic loci dispersed throughout the genome. How do functionally diverse loci come to share common regulatory motifs? A new paper finds that retrotransposons (RTEs) may play a role in providing common regulation to a group of functions ...

Trends in Microbiology, 2001
Transposable genetic elements (TGEs) produce major deleterious effects in the host organism yet they still spread through the populations of sexually reproducing organisms. TGEs can become established in sexual populations because sexual reproduction allows them to go to fixation if the reduction in fitness of the host is less than twofold.

Retrotransposon replication in plants
Current Opinion in Virology, 2013Retrotransposons comprise the bulk of large plant genomes, replicating via an RNA intermediate whereby the original, integrated element remains in place. Of the two main orders, the LTR retrotransposons considerably outnumber the LINEs. LINEs integrate into target sites simultaneously with the RNA transcript being copied into cDNA by target-primed ...

An unusually compact retrotransposon in maize
Plant Molecular Biology, 1989Unlike any other known plant transposon, the maize transposable element Bs1 is similar to the retrotransposons previously described in yeast and Drosophila. Bs1 is bounded by 302 bp identical long terminal repeats (LTRs), and it contains open reading frames with apparent amino acid sequence similarity to reverse transcriptase and other retroviral pol ...
