Near-infrared (NIR) light-induced repression of the reporter gene using a system based on the light-induced bacterial phytochrome photoreceptor 1 (BphP1) from R. palustris and its partner protein QPAS1. (A) Approach using the relocalisation of the activator to the plasma membrane. (B) Approach using the NIR light-induced “disruption” of the activator dimer. (C) NIR light-induced histone deacetylation of the reporter gene’s promoter region.
