Toxic arsenic initially accumulates in the nuclei of plants’ cells. This has been revealed by an X-ray examination of the aquatic plant rigid hornwort (Ceratophyllum demersum) using DESY’s X-ray source PETRA III. Even at comparatively low concentrations, the arsenic also floods the vacuole, a liquid-filled cavity which takes up most of the cell. The scientists report their findings in the Journal of Experimental Botany.
