Figure 4From: A systematic survey in Arabidopsis thaliana of transcription factors that modulate circadian parametersConfirmation of transcriptional clock phenotypes in constant dark. Seedlings harboring CCA1:LUC or CCR2:LUC reporter genes were monitored in constant darkness for 4–5 days. Representative traces of rhythmic expression of oxplants (pink squares) and wild-type (blue circles) are shown. (A, B) MYB3R2-ox, (C, D) bHLH69-ox. (A, C) CCA1:LUC, (B, D) CCR2:LUC.Back to article page
