Light Regulates Plant Alternative Splicing through the Control of Transcriptional Elongation
Light makes carbon fixation possible, allowing plant and animal life on Earth. We have previously shown that light regulates alternative splicing in plants. Light initiates a chloroplast retrograde signaling that regulates nuclear alternative splicing of a subset of Arabidopsis thaliana transcripts....

We have previously shown that light regulates alternative splicing in plants.

The light control of splicing and elongation is abolished in an Arabidopsis mutant defective in the transcription factor IIS (TFIIS).
