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.
羧基荧光素是一种胞质示踪剂,被应用于玉米幼苗伸长中胚轴基部或胚芽鞘顶端的切口处,并测量其运输情况和组织分布。羧基荧光素的长距离纵向胞质运输主要发生在维管束中。它从中胚轴维管束横向移动到中胚轴皮层,但存在一个较弱的屏障限制了其运动。在胚芽鞘-中胚轴节附近也存在部分胞质屏障。
