*Geographic origins of the ecotypes were collected from the donor , Arabidopsis 1001 Genome project database [75] and Swindell et al. [13].
This table represents geographic distribution of the 10 A. thaliana ecotypes and number of cold 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. Ecotype Col-0, which is a cold tolerant ecotype have very less number of cold regulated transcripts compare to others. On the other hand Cvi, the southernmost accession from a warm climate, exhibits more number of cold responsive transcripts. (Unique = Unique to the respective ecotype).
