【摘要】 用免疫荧光定位技术,辅以透射电镜方法,研究了大葱根尖细胞分裂周期中微管排列的变化。观察结果表明大葱根尖细胞周期中存在四种循序变化的微管排列的方式,即间期的周质微管、早前期带微管、纺锤体微管和成膜体微管。它们构成了高等植物分裂细胞中典型的微管周期。从透射电镜超微结构获得的资料解释和分析了荧光显微镜下所见到的微管的荧光图象。更多还原

【Abstract】 Using immunofluorescent localization techniques and TEM methods, the organization of microtubule arrays during the cell cycle of root tip cells of Allium fistulomm L. was studied. There are four basic types of microtubule organization, namely, interphase cortical microtubule, pre-prophase band microtubule, spindle microtubule and phragmoplast microtubule, which constitute the typical microtubule cycle in dividing cells of higher plants. The fluorescent figures of microtubules observed under fluorescent microscope were explained and analysed by the ultrastractural informations of microtubules obtained from TEM.更多还原
