用激光共聚焦显微镜观察了东北红豆杉木材压缩管胞皮层微管的形态特征。在次生壁形成过程中，它们与管胞轴成45°角。人工倾斜改变了MT的排列模式。带状MT在次级壁形成后期呈螺旋取向。这些结果表明，MTs可能控制纤维素微纤丝在次生壁中的定向和局部沉积。
Cortical microtubules (MTs) in differentiating compression wood tracheids ofTaxus cuspidatastems were visualized by confocal laser microscopy. They were oriented obliquely at an angle of about 45° to the tracheid axis during formation of the secondary wall. Artificial inclination altered the pattern of alignment of MTs. Banding MTs were helically oriented late during the formation of the secondary walls. These results indicate that MTs might control the orientation and localized deposition of cellulose microfibrils in the secondary walls of compression wood tracheids.
