Microarray-based expression profile of Arabidopsis NCX genes under various abiotic stress conditions. Heat maps show the fold changes in expression of Arabidopsis NCX genes in a root and b shoot tissues under different abiotic stress conditions such as salt, drought, osmotic, cold, heat, oxidative, genotoxic, wounding and UV/B stress. Heat maps were generated using microarray data obtained from AtGenExpress. Microarray data was obtained for different time points for different stresses viz 0.5 h, 1 h, 3 h, 6 h, 12 h and 24 h for both root and shoot tissues and analyzed with respect to control. Relative signal values are represented by color bar shown at the bottom of heat map; thereby green color representing downregulation, black signifies no change in expression and red shows upregulation
