Phytochrome Regulates Light-Dependent Alternative Splicing or Alternative Promoter Selection that Impacts Gene Expression and the Proteome in Response to Red Light
(A) Phytochromes regulate splicing factors, which results in the production of distinct mRNA molecules due to alternative splicing of a pre-mRNA molecule (Shikata et al., 2014).
(B) Phytochrome controls promoter selection, which results in the production of distinct pre-mRNA molecules during differential initiation of transcription. These processes are largely non-overlapping, as only 14% of transcripts regulated by alternative promoter selection were also subject to phytochrome-mediated alternative splicing (Ushijima et al., 2017). Both processes result in more complex proteomes that have functional implications. Colored boxes represent exons. Promoters that drive transcription are indicated by P (+ arrow).
