Abstract

The effect of amino acid starvation on cell division was studied in cells of Escherichia coli B. In this bacterial strain, deprivation of a required amino acid resulted in synchronous cell division upon restoration of the amino acid. This synchronization was apparently due to a shift forward in the cell cycle during the starvation. As a consequence, the cells divided at a size that was smaller than normal.

摘要

在大肠杆菌B细胞中研究了氨基酸饥饿对细胞分裂的影响。在这种细菌菌株中,去除一种必需氨基酸后,恢复该氨基酸时会导致细胞同步分裂。这种同步显然是由于饥饿期间细胞周期向前推移所致。结果,细胞分裂时的大小比正常情况小。
