Combined stress treatment of high salinity, osmotic pressure and heat to Arabidopsis thaliana

ABSTRACT: In natural habitats, plants are often exposed to multiple stresses. Most studies, however, for plant abiotic stress responses analyzed those to individual stress but not combined stresses. In this report, we performed comparison analyses of gene expression to individual stresses, salt, osmotic and heat, and to a combination of these three stresses, which mimics arid conditions. We show here that the combined stress treatment induces unique gene expression pattern but not a simple reflection of the additive effects of individual stresses. First, the number of genes induced by combined stresses (150 mM NaCl, 200 mM mannitol and 35°C heat) was much smaller when compared to the sum of those induced by individual stress treatments, while the number of genes downregulated by multiple stresses w
