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.
羧基荧光素是一种共质体探针，将其应用于黄化的玉米品种银皇后幼苗的中胚轴基部切口或胚芽鞘顶端，并测量其运输情况，确定其组织分布。羧基荧光素的长距离纵向共质体运输主要发生在维管束中柱。它从中胚轴中柱横向移动到中胚轴皮层，但存在一个较弱的屏障限制了这种移动。在胚芽鞘 - 中胚轴节附近也存在部分共质体屏障。
