Lead contamination has become a serious issue and approaches are continuously searched for lead removal. Plants. Landoltia punctata is a duckweed strain widely distributed in China and successfully employed for wastewater treatment [20]. Although previous studies indicated that L. punctata possessed the ability to accumulate a high content of starch (3%–75%) [21], the potential of duckweed as a novel bioenergy biomass was not recognized until recently [22]. This study globally analyzed the response to nutrient starvation in order to investigate the starch accumulation in duckweed (Landoltia punctata).L. Crawford – dotted duckmeat Subordinate Taxa.
