From: Genome-scale cold stress response regulatory networks in ten Arabidopsis thalianaecotypes
Heat map visualization of the cold transcriptome of the ten ecotypes. The heat map visualizes hierarchical clustering (with Pearson’s correlation coefficient using average linkage method) of top 1000 cold regulated transcripts based on gene expression fold change ratios compared to their respective controls from 10 different ecotypes. Genes are shown as columns and ecotypes are shown as rows. As a global observation, this heat map indicates differential regulation signatures in response to non-freezing cold treatment in different A. thaliana ecotypes. Cold tolerant ecotype Col-0 ecotype is distinctly separated out from others.
