Excision of Helitron transposons in maize.
Helitrons are novel transposons discovered by bioinformatic analysis of eukaryotic genome sequences. They are believed to move by rolling circle (RC) replication because their predicted transposases are homologous to those of bacterial RC transposons. We report here evidence of somatic Helitron excision in maize, an unexpected finding suggesting that Helitrons can exhibit an excisive mode of transposition.
