To fill the void regarding the availability of high-quality, genome-scale sequence data in this part of the evolutionary tree, we have sequenced, assembled, annotated, and performed a preliminary analysis on the 150 megabase genome of Mnemiopsis.

A number of studies on Mnemiopsis have led to a better understanding of many key biological processes, including regeneration and axial patterning, and these studies have contributed to the emergence of Mnemiopsis as an important model for evolutionary and developmental studies.

Invasion genomics uncover contrasting scenarios of genetic diversity in a widespread marine invader.
