|Abstract:||Thellungiella halophila, a close relative of Arabidopsis thaliana, is a halophyte that can survive in sea water. Microarray transcript profiling and intensity analysis, quantitative RT-PCR, and metabolite profiles revealed shared and divergent responses to salt stress in the two species. Sixty percent of regulated genes distinguished Thellungiella from Arabidopsis. Analysis of the differences showed that Arabidopsis took a global defense strategy that required bulk protein synthesis, while Thellungiella induced genes functioning in protein folding, post-translational modification, and protein redistribution. The microarray results were supported by transcript intensity analyses and metabolite profiling results, pointing towards a stress-anticipatory preparedness in Thellungiella.|
