Loss of heat‐shock acquisition of thermotolerance in yeast is not correlated with loss of heat‐shock proteins [PDF]

open access: yesFEBS Letters, 1986
Yeast cells when subjected to a primary heat shock, defined as a temperature shift from 23 to 37° for 30 min, acquired tolerance to heat stress (52°C/5 min). Primary heat shocked cells incubated at 23°C for up to 3 h, progressively lost thermotolerance but retained high levels of the major heat‐shock proteins as observed on polyacrylamide gels.
