Multiple waves of gene expression at dawn.  Genes encoding DNA binding proteins were clustered into 10 groups using CLUST based on their gene expression pattern at 22oC in Col-0.  (A) The gene expression pattern of these clusters is shown for Col-0 at both 22oC and 27oC.  (B) Previous experiments by Rugnone et al, 2013 identified genes that are sensitive to light in a time-of-day dependent way.  Many of these genes that were identified as being light induced or repressed in the day and night were also found to be expressed within the clusters in (A).  We use a table instead of a Venn Diagram for clarity.  A coloured block indicates that there is a p-value < 0.05 based on a Fisher exact test with Bonferroni correction (red if it is more overlap than expected and blue if there is less than expected).  Bold indicates that the p-value <0.001.  (C) The gene expression pattern for those clusters in (A) for additional strains at 22oC.  Note that this experiment used fewer time points and also sequencing was done with Lexogen instead of Illumina.  Due to space, the names of the strains were abbreviated as follows: hsfA1Q was labelled as hsfQ, phyAphyBcry1cry2 was labelled as phyABcry12, and prr5prr7prr9 was labelled as prr579.
