Spirodela polyrhiza is a monocotyledon belonging to family Lemnaceae. The Lemnaceae, commonly called Duckweeds, are small, widely distributed, fast growing flowering plants that grow floating in still or slow moving fresh water. They are highly adaptive and can withstand environmental toxicity. They therefore make an important source of biofuel feedstock and for the removal of pollutants like arsenic from the environment. Spirodela polyrhiza is an ideal system for biofuels, bioremediation and carbon cycling due to their aspects of fast-growing, direct contact with media and smallest genome size (~150 Mb). A comprehensive genomic study of Spirodela polyrhiza was published in February 2014. The results provide insights into how this organism is adapted to rapid growth and an aquatic lifestyle.
