Louisiana State University.
The Mississippi River Delta is home to the world’s largest contiguous swath of Phragmites australis, or more commonly known as the common reed. But the plant that can grow to nearly 20 ft. and has been a critical component in stabilizing the state’s coastal erosion is not actually native to Louisiana—well, not entirely. There are multiple P. australis genotypes. P. australis subspecies (ssp.) americanus is the native subspecies in the U.S. and Canada. However, Phragmites australis ssp. australis originated in central Europe and was subsequently introduced to the U.S. where it is now considered to be one of the most problematic invasive species in North America. "Novel genome characteristics contribute to the invasiveness of Phragmites australis (common reed)" in Molecular Ecology and recently featured in an edition of The Scientist, LSU researchers collaborated with Tulane University and the U.S. Geological Survey to study the genomic bases of P. australis and to investigate what exactly makes the invasive reed grass subspecies thrive in wetlands, in comparison to its native counterpart.
