tool for understanding the molecular mechanisms of metal homeostasis. Such improved
understanding may enable bioengineering of organisms with improved nutrition and
bioremediation capacity. We report here that Chlamydomonas reinhardtii can accumulate
manganese (Mn) in proportion to extracellular supply, up to 30-fold greater than its typical
quota and with remarkable tolerance. As visualized by X-ray fluorescence microscopy and …
