Webthat HSFA2 is the most highly heat-induced HSF and hsfa2 KO mutants are the only simple mutants which are completely unable to acquire thermotolerance. This is partly explained by the fact that HSFA2 is able to induce its own expression. However, the mechanism is not specific to HSFA2 as other HSFs can also exert positive feedback on other HSFs.
