A rice Tc1/mariner-like element transposes in yeast.

The Tc1/mariner transposable element superfamily is widely distributed in animal and plant genomes. However, no active plant element has been previously identified. Nearly identical copies of a rice (Oryza sativa) Tc1/mariner element called Osmar5 in the genome suggested potential activity. Previous studies revealed that Osmar5 encoded a protein that bound specifically to its own ends. In this ...

Transposition of a rice Mutator-like element in the yeast Saccharomyces cerevisiae.

Mutator-like transposable elements (MULEs) are widespread in plants and are well known for their high transposition activity as well as their ability to duplicate and amplify host gene fragments. Despite their abundance and importance, few active MULEs have been identified. In this study, we demonstrated that a rice (Oryza sativa) MULE, Os3378, is capable of excising and reinserting in yeast (S...

Ty3 transposes in mating populations of yeast: a novel transposition assay for Ty3.

Ty3 is a retrotransposon of Saccharomyces cerevisiae that integrates just upstream of the transcription initiation site of genes transcribed by RNA polymerase III. Ty3 transcription is pheromone-inducible in haploid cells and is mating-type regulated in diploid cells. The specificity of Ty3 integration was exploited in the design of a novel target into which transposition of Ty3 elements could ...

Crawler, a novel Tc1/mariner-type transposable element in Aspergillus oryzae transposes under stress conditions.

A novel active transposable element, designated Crawler, has been isolated from an industrial strain (OSI1013) of Aspergillus oryzae as an insertion sequence within the niaD gene encoding nitrate reductase. It is 1290bp in length with imperfect terminal inverted repeats of 28bp and is flanked by 2bp (TA) target site duplications. It contains an open reading frame with no introns that encodes a ...

Rice MULEs Transpose in Yeast

Named for their mutational effect, Mutatorlike transposable elements (MULEs) in plant genomes transpose frequently and can also acquire pieces of genomic DNA, forming Pack-MULEs; movement and recombination of genomic fragments by Pack-MULEs can alter the regulation of existing genes and may form new genes (Jiang et al., 2004; reviewed in Chénais et al., 2012). MULEs have terminal inverted repea...
