Sunlight is essential for plants: Not only as an energy source but also as information for their growth cycle. Therfore they need receptors to detect different light wavelengts. Ultraviolet B (UVB) light can be perceived with photoreceptor UV resistance Locus 8 (UVR8) [1]. This UVR8 receptor derives drom Arapidopsis thaliana [2].

Usage and Biology

In the absecne 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]
