Heatmap was calculated using the Jaccard index for ecotypes. Jaccard-indices comparing the similarity in the sets of bands regulated by SDS PAGE in each of 6 ecotypes. Abbreviations: D, drought stress; SA, salicylic acid; DSA, drought stress∗salicylic acid; DSAE, drought stress∗salicylic acid∗Ecotype. Ecotypes: Kalati (E1), Tazehabad (E2), Fetrezamin (E3), Gavdareh (E4), Baharband (E5) and Telvar (E6).
