A new precipitation technique provides evidence for the permeability of Casparian bands to ions in young roots of corn (Zea mays L.) and rice (Oryza sativa L.) por Ranathunge, Kosala, Steudle, Ernst, Lafitte, Renee

“…Asymmetric development of precipitates suggested that the cation, Cu2+, moved faster than the anion, [Fe(CN)6]4–, through cell walls including CBs. Using Chara cell wall preparations (‘ghosts’) as a model system, it was observed that, different from Cu2+, ferrocyanide ions remained inside wall‐tubes suggesting a substantially lower permeability of the latter which agreed with the finding of an asymmetric development of precipitates. …”
