  abstract = {{R}etrotransposons are the main components of eukaryotic genomes, representing up to 80% of some large plant genomes. {T}hese mobile elements transpose via a "copy and paste" mechanism, thus increasing their copy number while active. {T}heir accumulation is now accepted as the main factor of genome size increase in higher eukaryotes, besides polyploidy. {H}owever, the dynamics of this process are poorly understood. {I}n this study, we show that {O}ryza australiensis, a wild relative of the {A}sian cultivated rice {O}. sativa, has undergone recent bursts of three {LTR}-retrotransposon families. {T}his genome has accumulated more than 90,000 retrotransposon copies during the last three million years, leading to a rapid twofold increase of its size. {I}n addition, phenetic analyses of these retrotransposons clearly confirm that the genomic bursts occurred posterior to the radiation of the species. {T}his provides direct evidence of retrotransposon-mediated variation of genome size within a plant genus.},
