Abstract

The paper describes the forward streaming, growth, and division of the vegetative cell of Basidiobolus ranarum. The cell is several hundred microns long and has a single large nucleus. Mitosis is invariably followed by cell division. Both processes have been studied in the living cell by ordinary and phase contrast microscopy. Mitosis is accompanied by a temporary coarsening of the organisation of the cytoplasm and a considerable slowing down of the rate of growth of the cell wall tube. Fixed and stained preparations have shown that there is a large number of small chromosomes and that the mitotic spindle is formed from the nucleolus. Basidiobolus appears suitable for observations on the cell duplication cycle and the physiology of mitosis.

摘要

本文描述了蛙粪霉营养细胞的向前流动、生长和分裂。该细胞长数百微米,有一个大的细胞核。有丝分裂总是伴随着细胞分裂。这两个过程都已通过普通显微镜和相差显微镜在活细胞中进行了研究。有丝分裂伴随着细胞质组织的暂时变粗以及细胞壁管生长速率的显著减慢。固定和染色的标本显示有大量小染色体,且有丝分裂纺锤体由核仁形成。蛙粪霉似乎适合用于观察细胞复制周期和有丝分裂生理学。
