Neurospora crassa conidiospore germlings exposed to a heat shock (30-45 C) rapidly accumulated trehalose and degraded glycogen, even in the presence of cycloheximide. This phenomenon was also rapidly reversible upon return of the cells at 30 degrees C. Trehalose accumulation at 45 degrees C demanded an exogenous source of carbon and either glucose or glycerol fulfilled such requirement. Experiments with the cyclic AMP-deficient cr-1 mutant suggested that the effects of temperature shifts on… CONTINUE READING
