Fecha de publicación: | 2007 | Editor: | Elsevier | Citación: | Journal of Plant Physiology 164: 1235-1238 (2007) | Resumen: | The microlocalisation of cadmium (Cd) at the tissue–cellular level in Lupinus albus L. cv. Multolupa was determined by energy-dispersive X-ray microanalysis (EDXMA). Experimental plants were grown on Cd-treated (0 and 150 mM) perlite for 35 days. In leaves, Cd was found inside cells (cytoplasm or vacuoles), especially in the vascular bundle cells. Cd-induced damage of the chloroplast structure was also detected. EDXMA of the roots showed the cell wall to be the main area of Cd binding at the cellular level; only a small amount of Cd was found in the vacuoles. At the tissue level, a decreasing Cd gradient was seen from the outer to the inner root cortical parenchyma. Cd and S were found co-localised in the vascular cylinder. | Descripción: | 4 pages, figures, and tables statistics. | Versión del editor: | http://dx.doi.org/10.1016/j.plph.2006.11.011 | URI: | http://hdl.handle.net/10261/29055 | DOI: | 10.1016/j.jplph.2006.11.011 | ISSN: | 0176-1617 |
