ABSTRACT
Retrotransposons are mobile genetic elements that accomplish transposition via an RNA intermediate that is reverse transcribed before integration into a new location within the host genome. They are ubiquitous in eukaryotic organisms and constitute a major portion of the nuclear genome (often more than half of the total DNA) in plants. Furthermore, they are dispersed as interspersed repetitive sequences throughout most of the length of all host chromosomes. These unique properties of retrotransposons have been exploited as genetic tools for plant genome analysis. Major applications are in determining phylogeny and genetic diversity and in the functional analyses of genes in plants. Here, recent advances in molecular markers, gene tagging and functional genomics technologies using plant retrotransposons are described.
