A red/blue optoswitch for temporal control of chloroplast transcription and biogenesis in Arabidopsis.
Using a red/blue optoswitch with monochromatic LEDs, blue-light-induced expression of a PAP7 construct (silent under red light) reconstituted PEP at any developmental time point in the Arabidopsis pap7-1 mutant and enabled proper chloroplast biogenesis that r…
