Abstract

The occurrence of axial cytoplasmic microtubules (25 nm in diameter) and of microfilaments (7 nm in diameter) associated in bundles just below the plasma membrane of the yeast Schizosaccharomyces pombe is described. Both types of cytoplasmic filamentous structures were present in the cell division cycle mutant cdc 12-112 of this fungus incubated for 6 h at the restrictive temperature of 35 degrees C. Microtubules and microfilaments probably function in septum formation and (or) in the volume-related control of the terminal phenotype of the mutant.

摘要

本文描述了在粟酒裂殖酵母细胞膜下方成束存在的轴质微管(直径25纳米)和微丝(直径7纳米)。在35摄氏度的限制温度下培养6小时后,这种真菌的细胞分裂周期突变体cdc 12 - 112中存在这两种类型的细胞质丝状结构。微管和微丝可能在隔膜形成和(或)突变体终末表型的体积相关控制中发挥作用。
