Abstract

UV RESISTANCE LOCUS 8 (UVR8) is a UV-B photoreceptor protein present in plants that is responsible for UV-B induced photomorphogenic responses. UV-B absorption by UVR8 causes the homo-dimeric protein to monomerise, hence initiating gene expression and physiological responses. The activity of UVR8 is tightly controlled by the proteins REPRESSOR OF UV-B PHOTOMORPHOGENESIS 1 and 2 (RUP1 and RUP2), which regulate the balance between the UVR8 homo-dimer and monomers that initiate signal transduction. There has been some research to identify external stimuli that regulate RUP gene expression; however much more needs to be done to obtain a complete picture. Here, these data presented in the thesis show the different abiotic stimuli that influence RUP expression and thus how these impact on UV-B perception in A. thaliana.
