Subcellular localization of copper in the root cells of Allium sativum by electron energy loss spectroscopy (EELS).


Ultrastructural investigation of the root cells of Allium sativum L. exposed to three different concentrations of Cu (1, 10 and 100 microM) for 9 days was carried out using transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS). The results presented here indicate that excess Cu induces ultrastructural changes such as strong… (More)
