The replicative retrotransposon life cycle offers the potential for explosive increases in copy
number and consequent inflation of genome size. The BARE-1 retrotransposon family of …

The barley BARE-1 is a transcribed, copia-like retroelement with well-conserved functional
domains, an active promoter, and a copy number of at least 3× 10 4. We examined its …

The BARE-1 retrotransposon occurs in more than 10 4 copies in the barley genome. The
element is bounded by long terminal repeats (LTRs, 1829 bp) containing motifs typical of …

Retroposition is widely found to play essential roles in origination of new mammalian and
other animal genes. However, the scarcity of retrogenes in plants has led to the assumption …

Organisms with large genomes contain vast amounts of repetitive DNA sequences, much of
which is composed of retrotransposons. Amplification of retrotransposons has been …

The replicative spread of retrotransposons in the genome creates new insertional
polymorphisms, increasing retrotransposon numbers and potentially both their share of the …

Retroviruses and LTR retrotransposons comprise two long-terminal repeats (LTRs)
bounding a central domain that encodes the products needed for reverse transcription …

Abstract Long Terminal Repeat (LTR) retrotransposons are ubiquitous components of plant
genomes. Because of their copy-and-paste mode of transposition, these elements tend to …

A large fraction of the genomes of grasses, members of the family Graminae, is composed of
retrotransposons. These elements resemble animal retroviruses in their structure and …

Retroviruses and retrotransposons make up the broad class of retroelements replicating and
transposing via reverse transcriptase. Retroelements have recently been found to be …
