Sunlight is essential for plants: Not only as an energy source but also as information for their growth cycle. Therefore they need receptors to detect different light wavelengths. Ultraviolet B (UVB) light can be perceived with photoreceptor UV resistance Locus 8 (UVR8) [1]. This receptor derives from Arapidopsis thaliana and contains its core domain (amino acids 12-381) [2]. The receptor reacts best to light of the wavelength 311 nm.
Biology and Usage
In the absence of UVB light UVR8 forms homodimers. This is its closed configuration. When UVB light is perceived UVR8 monomerizes and changes into its open configuration. UVR8 is then able to recruit COP1 [2]. This interaction is disrupted when UVB radiation stops. Plants use this mechanism to perceive UVB light and respond with photomorphogenesis or react to UVB induced stress [3].
Freiburg 2013 used this part to engineer a UVB light induced mechanism to activate gene expression. You need a combination of these BioBricks: Cas9-UVR8, COP1-VP16, RNaimer
