^*Geographic origins of the ecotypes were collected from the donor, TAIR and the Arabidopsis 1001 Genome project database.

Geographic distribution of the 10 A. thaliana ecotypes and number of heat regulated genes in each of the ecotypes (p ≤ 0.01). Up and down regulation was calculated based on fold change ratios compared to respective untreated controls in individual ecotypes. (Unique, Unique to the respective ecotype).
