Four layers of parenchyma cells are usually present in the cortex (Figure 2A), but lacking the exodermis with suberin; the endodermis is present (Figure 2A), but without evident Casparian strips.
Optimum concentration of nutrients and heavy metals delayed the entry of metals into the roots by stimulating a lignified exodermis and thereby subsidized to a higher metal tolerance (Cheng et al., 2012).
