东北红豆杉（Taxuscuspidata）管胞分化过程中径向壁上的皮层微管阵列在初生壁形成时随机取向。随着细胞的扩张，MT的取向逐渐从纵向变为横向。在初生壁的形成过程中，分化管胞的MT在未来的气管间有界纹孔的部位局部消失。在进一步分化的管胞中，观察到圆形带的MT周围的边缘发展有边纹孔。
Arrays of cortical microtubules (MTs) on radial walls in differentiating tracheids of Taxus cuspidata were randomly oriented when primary walls formed. The orientation of MTs changed progressively from longitudinal to transverse as cells expanded. During formation of primary walls, MTs in differentiating tracheids disappeared locally at sites of future intertracheal bordered pits. In further differentiated tracheids, circular bands of MTs were observed around the edges of developing bordered pits.
