Organization of tubulin cytoskeleton in epidermis and cortex cells in different root growth zones in Brassica rapa L. 6-day-old seedlings under clinorotation has been investigated. It was shown that changes in cortical microtubules orientation occur only in the distal elongation zone. In control, cortical microtubule arrays oriented transversely to the root long axis. Whereas under clinorotation an appearance of shorter randomly organized cortical microtubules was observed. Simultaneously, a significant decrease in a cell length in the central elongation zone under clinorotation was revealed. It is suggested that the decline of anisotropic growth, typical for central elongation zone cells, is connected with cortical microtubules disorientation under clinorotation.
对处于回转条件下的6日龄白菜型油菜幼苗不同根生长区的表皮细胞和皮层细胞中微管细胞骨架的组织情况进行了研究。结果表明，皮层微管方向的变化仅发生在远端伸长区。在对照中，皮层微管阵列垂直于根的长轴排列。而在回转条件下，观察到出现了较短的随机排列的皮层微管。同时，发现在回转条件下中央伸长区的细胞长度显著缩短。有人认为，中央伸长区细胞典型的各向异性生长的下降与回转条件下皮层微管的方向紊乱有关。
