Gene expression diversity of GLK1 candidate target genes across 727 Arabidopsis accessions. A Heatmap showing the relative gene expression of the candidate target genes (n = 136) of the top 100 GLK1 binding events across 727 Arabidopsis accessions. Rows represent genes and column accessions. Three clusters of accessions and three clusters of genes were identified and labeled in the heatmap depending on their particular expression patterns. B Expression of GLK1 in the three clusters identified in Fig. 1A. The expression is significantly different (t-test; p-value< 2*10−16) between A1 vs A2, and A1 vs A3, and slightly significant (p-value< 0.03) between A2 vs A3. C Distribution of the monthly standard deviation (SD) of solar radiation of the coordinates from the regions where the accessions were collected. Groups A1 and A2 were significantly different (p-value< 10−7; t-test). D Map representing the location of the 727 Arabidopsis accessions. Only a subsection of the map is plotted, see Suppl. Fig. 1 for a complete map. A1 accessions are plotted in blue, A2 in red, and A3 in green
