| 摘 要： | 以陆地棉纤维为实验材料,研究了微管骨架在棉纤维细胞伸长阶段的功能.研究结果表明,在快速伸长期纤维细胞内,微管骨架以垂直于细胞伸长轴方向垂直排列,微纤丝的结构和分布与微管骨架保持一致,细胞壁表面平滑.经过微管阻断剂秋水仙素处理的纤维细胞内,微纤丝的结构和分布受到损坏,细胞壁表面出现颗粒状突起,纤维细胞的伸长也受到明显抑制.以上实验结果表明微管骨架在棉纤维细胞的伸长阶段具有重要的功能.

| Abstract: | The role of microtubules during cotton(Gossypium hirsutum) fibers elongation was studied.The results indicated that microtubules were oriented transverse to the cell long axis and microfibrils deposition pattern was always coordinated with microtubule arrays during fibers fast growth periods.In the presence of colchicines,a large number of microtubule fragments and disorganized microfibrils deposition were found.At the same time,there were many waves on the cell wall surfaces compared to control smooth surface.In addition,the fibers elongation were remarkably inhibited. |
