Doubling genome size without polyploidization: Dynamics of retrotransposition-driven genomic expansions in Oryza australiensis , a wild relative of rice

Retrotransposons are the main components of eukaryotic genomes, representing up to 80% of some large plant genomes. These mobile elements transpose via a "copy and paste" mechanism, thus increasing their copy number while active. Their accumulation is now accepted as the main factor of genome size i... View More
