  • Cells were grown to exponential phase in YE medium at 32°; a fraction of the culture was shifted to 19° for 20 hr. Samples were taken before and after shift and cell length was determined as described in Materials and Methods. Length of septating cells is indicated, with standard deviation: n = 50 for each condition.
