Figure 5From: Light has a specific role in modulating Arabidopsis gene expression at low temperatureA northern blot analysis of three chloroplast encoded transcripts ( PsbA , PsbC and PetB ) after Control (Ctr), Cold/Light (C/L), Cold/Dark (C/D) and Dark (D) treatments. Numbers indicate the quantities of respective mRNAs after each treatment with value 1.0 for the control. Three independent northern blots were used for quantification against 16S rRNA.Back to article page
