title: Tissue to tissue symplastic communication in the shoots of etiolated corn seedlings.
abstract: Carboxyfluorescein, a symplastic probe, was applied to the cut mesocotyl base or coleoptile apex of etiolated Zea mays cv. Silver Queen seedlings and its transport measured and tissue distribution determined. Long-distance longitudinal symplastic transport of the carboxyfluorescein was mainly in the vascular stele. It moved laterally from the mesocotyl stele to the mesocotyl cortex but the presence of a weak barrier limited the movement. A partial symplastic barrier was also present near the coleoptile-mesocotyl node.
