>Results for EDTA were not consistent with our present understanding of restrictions on the uptake of complexes across plamsalemma membranes or via apoplastic or passive routes. Others have reported endodermal cells as more permeable than other root plasma membranes and this coupled with a developing awareness of aquaporins may help explain the selectivity toward EDTA chelates of lower charge (Tanton and Crowdy, 1972a, b).
