Inhibition of hypocotyl growth is a well-established UV-B-induced photomorphogenic response that mediated by the UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8). However, molecular mechanism which UVR8 signaling triggers inhibition poorly understood. The bZIP protein ELONGATED HYPOCOTYL 5 (HY5) functions as main positive regulatory transcription factor in pathway, with HY5-HOMOLOG (HYH) playing minor role. here we demonstrate hy5 hyh double mutants maintain significant UVR8-dependent...
Plants have evolved complex photoreceptor-controlled mechanisms to sense and respond seasonal changes in day length. This ability allows plants optimally time the transition from vegetative growth flowering. UV-B is an important part intrinsic sunlight; however, whether how it affects photoperiodic flowering has remained elusive. Here, we report that, presence of UV-B, genetic mutation REPRESSOR OF PHOTOMORPHOGENESIS 2 ( RUP2 ) renders facultative long plant Arabidopsis thaliana a...
