Abstract: | Background
Stowaway elements are short, non-autonomous DNA transposons categorized as miniature inverted-repeat transposable elements (MITEs).
The high MITE copy number in grass genomes suggests an active history of amplification and insertion, but ongoing MITE activity
has only rarely been seen, and ongoing Stowaway activity has never been observed. Thus, a phylogenetic perspective on presence vs. absence of elements in an aligned data
set can provide valuable historical insights into the dynamics of MITE acquisition and loss. |
