Investigating ecological effects of polyploidization in a cosmopolitan grass genus

Polyploidization, the process whereby an organism receives two whole copies of its parents’ genomes (instead of half of each parents’ genome), is very common among plants and is thought to be an important mechanism for creating new species (polyploids).

The role of polyploidy in facilitating plant invasions

Much remains to be understood about why some introduced species become invasive whereas others do not. Recently, polyploidy (whole genome duplication) has been proposed as an important determinant of invasiveness in plants.
