Stowaway miniature inverted repeat transposable elements are important agents driving recent genomic diversity in wild and cultivated carrot.

ABSTRACT:

Background

Miniature inverted repeat transposable elements (MITEs) are small non-autonomous DNA transposons that are ubiquitous in plant genomes, and are mobilised by their autonomous relatives. Stowaway MITEs are derived from and mobilised by elements from the mariner superfamily. Those elements constitute a significant portion of the carrot genome; however the variation caused by Daucus carota Stowaway MITEs (DcStos), their association with genes and their putative impact on genome evolution has not been comprehensively analysed.

Results

Fourteen families of Stowaway elements DcStos occupy about 0.5% of the carrot genome. We systematically analysed 31 genomes of wild and cultivated Daucus carota, yielding 18.5 thousand copie
