Abstract
Salicylic acid (SA) could be involved in the development of tolerance to abiotic stresses, to heat shock in particular. Under normal conditions (26°C), treatment with SA improved the tolerance of heterotrophic Arabidopsis thaliana (L.) Heynh culture to severe heat shock (50°C). Under mild heat shock (37°C) inducing the development of thermotolerance, the presence of SA, in contrast, reduced the capability of arabidopsis cells to tolerate high temperature (50°C) and simultaneously suppressed induction of HSP synthesis (Hsp101 and Hsp17.6) important for the development of induced thermotolerance. Since SA suppressed cell respiration and activated the alternative pathway of electron transport, SA is supposed, by modulating mitochondria functions, to be an endogenous regulator of plant stress gene expression.
