Abstract
Salicylic acid (SA) is an important signal molecule in the development of plant resistance to biotic stress. Exogenous applying of high SA concentrations led to programmed cell death (PCD) of A. thaliana cells. Cells incubation at mild heat shock was accompanied by the induction of heat shock proteins (HSPs) synthesis and resulted in the decreasing of the cell death from SA treatment (cross resistance). This cross resistance is supposed to be caused by the HSPs ability to inhibit PCD in plants.
