Abstract

SYNOPSIS. Heat shock and stationary‐phase conditions both cause fusion of nucleoli. In both cases the process is reversed when the cell is returned to normal physiological growth conditions. Fusion of nucleoli during the cell cycle of logarithmically growing cells was not observed. Likewise, fusion of nucleoli was not observed when the Padilla and Cameron(8) method of synchronization was used. The macronuclei of cells synchronized by the 1 cold‐shock per cycle method(8) more closely resembled macronuclei of log‐phase cells than did the macronuclei of cells synchronized by the Scherbaum and Zeuthen(12) heat‐shock method.
