A compilation of existing data on higher plant responses to heat‐shock temperatures has been utilized to produce a biochemically based model of integrated cellular responses to elevated temperatures. This model describes a potential mechanism for the triggering of several biochemical responses to a thermally induced leakage of extracellular or vacuolar ions into the cytoplasm. It seems possible that many of the observed heat‐shock responses are involved in the protection of (a) enzymes from inactivation and (b) nucleic acids from cleavage induced by the presence of elevated levels of specific metals.
