Plant Retrotransposons

Annual Review of Genetics, 1999
▪ Abstract  Retrotransposons are mobile genetic elements that transpose through reverse transcription of an RNA intermediate. Retrotransposons are ubiquitous in plants and play a major role in plant gene and genome evolution. In many cases, retrotransposons comprise over 50% of nuclear DNA content, a situation that can arise in just a few million ...

Retrotransposon Gene Engineering

Nature Biotechnology, 1991
We have used a mobile mouse VL30 genetic element together with retroviral helper cells to efficiently transmit and express chimeric foreign gene sequences in murine and human cells. The construct comprised a cDNA copy of retrotransposon NVL3, an internal promoter [rat cytosolic phosphoenolpyruvate carboxykinase (PEPCK, EC 4.1.1.32)] and an expressed ...

Fidelity of Retrotransposon Replication

Annals of the New York Academy of Sciences, 1999
ABSTRACT: Ty1, the genetically tractable retrotransposable element found in the yeast Saccharomyces cerevisiae, closely resembles vertebrate retroviruses both in structure and in mechanism of replication. By direct sequence analysis, we examined the rate and spectrum of new mutations appearing during a single cycle of Ty1 replication.

Retrotransposon families in rice

Molecular and General Genetics MGG, 1992
Three 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.

True Homoplasy of Retrotransposon Insertions in Primates

Systematic Biology, 2018
How 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,
