Comparing analysis of elements sub-cellular distribution in Kandelia obovata between SEM-EDX and chemical extraction.

Highlights: [•] Image analysis allowed us to detect the distribution of metals in K. obovata tissue. [•] Cell wall binding was involved in metal tolerance of K. obovata. [•] The root epidermis provided a major barrier to the transport of metals in K. obovata. [•] Metal detoxification was influenced by the sub-cellular fractions. [ABSTRACT FROM AUTHOR]
