Fig. 2. — EC activity is essential for the SD transcriptome. (A) Clustering of gene expression under SD (10-h day, 14-h night) and LD (14-h day, 10-h night) reveals groups of genes that are activated (e.g., clusters 4 and 2) and repressed (e.g., clusters 7, 6, and 3) by SD photoperiods. These clusters become largely daylength neutral in the elf3-1 elf3-2 background (line 246U1.6a2: 1 nucleotide insertion in ELF3-1 locus: two nucleotide deletion in ELF3-2 locus). Values for log2(TPM ratio) > 2 or < −2 are transformed to the range of ± 2. (B) Examples of circadian and flowering time genes that lose their photoperiod responsiveness in elf3-1 elf3-2 and lux (line 120T7, two nucleotide insertion). Blue and red ribbons denote the overall behavior of the relevant cluster in SD and LD, respectively.
