Global increase of RNA polymerase II activity and transcriptome size during Arabidopsis photomorphogenesis

Key Points

• Increased RNA polymerase II activity leads to a larger transcriptome during photomorphogenesis.
• The study shows significant enhancement in expression of light-regulated genes.
• Observational analysis focusing on Arabidopsis indicates that light exposure intensifies gene regulation.
• This may enable better understanding of plant responses to light and environmental changes.
