Figure 2From: Retrotranspositions in orthologous regions of closely related grass speciesOrganization of LTR-retrotransposons at the orp1 locus. The maize orp1 region on maize chromosome 4S has three-layer nested LTR retrotransposons. This region also contains the highest number of LTR retrotransposons. A color code for the various retrotransposon families has been added.Back to article page
