Transposable elements of Agavoideae.

Subfamily Agavoideae includes about 640 species, many of which are used for a wide variety of purposes: fermentation of sap to make liquor (tequila, mezcal), fiber (sisal), horticulture, and biofuel production. Additionally, the lineage represents broad variation in ecological, life history, and genomic traits, representing unique opportunities to explore relationships among these traits. However, relatively few genomic resources exist for Agave or related genera, though a genome sequencing project is underway for Agave. In particular, few transposable elements have been described in these species. For this study, we compared multiple approaches to characterization of repetitive DNA from existing genomic and transcriptomic sequence data. We discuss the relevance of transposable element diversity in our selection of Agavoideae, including possible roles for these transposable elements in shaping genomic evolution. Additionally, we investigate the impact of a previously described whole genome duplication event had on transposable element diversity and composition in members of the Agavoideae Bimodal Karyotype clade.
