β-cc Elicits a SCL14-Like Response Involving the TGA and MYC Transcription Factors.

(A) Number of genes whose expression increases or decreases more than 1.5-fold in log₂ values compared with the respective controls in the transcriptome of β-cc-treated wild-type plants (4 h treatment, β-cc) and of the ch1 mutant line under high-light stress (ch1 HL, 1200 μmol photons m⁻² s⁻¹ at 10°C for 24 h).

(B) Transcription factors cis element enrichment in the regulatory regions (−1000 + 50 bp from the starting codon) of the common genes.

(C) ANAC002, ANAC032, ANAC081, and ANAC102 expression levels (fold on control levels) in wild-type plants exposed to β-cc or under excessive light stress (HL), measured by RT-qPCR. Every value showed a significant difference when tested against CTRL conditions (P < 0.01). Error bars = +sd between the four technical replicates from pools of three plants per treatment. Two full experimental replicates.
