In this study, we show ion profiles in the xylem and leaf tissue, concerning with the physiological function of epithem cells of hydathode in ion metabolism in a barley primary leaf. Combination of physiological measurements of ion contents, visualization of cell functions and expression measurements of transporters along longitudinal leaf tissue suggested that a plant leaf has a new aspect involving with inorganic ion metabolism.
