Analysis of leaves of UV resistance locus 8 uvr8-1 and transcription factor hy5-1 mutants following exposure to a physiological dose of UV-B. Results provide insight into the role of UVR8 and HY5 in the response to UV-B radiation and into the mechanisms of UV-B perception and signal transduction.

(Submitter supplied) We analysed global gene expression changes in Arabidopsis thaliana in response to 6h UV-B, applied at the same low level that was seen to promote subsequent UV-B stress tolerance, in order to elucidate the transcriptional reprogramming that leads to UV-B acclimation.

(Submitter supplied) We show that longer-term inhibition of shade avoidance in Arabidopsis is sustained by ELONGATED HYPOCOTYL 5 (HY5) and HY5 HOMOLOG (HYH) which, together, regulate transcriptional reprogramming of genes involved in hormone signalling and cell wall modification.

(Submitter supplied) Plants use sunlight as a source of energy for photosynthesis but also as an important environmental cue to regulate growth, development and light acclimation. Wavelengths in the UV-B (280-315 nm) and UV-A/blue (315-500 nm) regions of the spectrum are perceived by UV RESISTANCE LOCUS 8 (UVR8) and cryptochromes (CRY1 and CRY2), respectively. Despite recent advances in our understanding of how these photoreceptors promote photomorphogenesis, very little is known about the molecular mechanisms regulated by UVR8 and CRYs in sunlight exposed plants. more...

(Submitter supplied) LONG HYPOCOTYL 5 (HY5) is a basic leucine zipper transcription factor (TF) that functions downstream of multiple families of photoreceptors. Mutations in the HY5 gene cause a myriad of aberrant phenotypes in Arabidopsis, including elongated hypocotyl, reduced accumulation of pigments, halted chloroplast development in greening hypocotyls, altered root morphology and defective hormonal and stimulus responses. more...

(Submitter supplied) Exposure to high irradiance results in dramatic changes in nuclear gene expression in plants. However, little is known about the mechanisms by which changes in irradiance are sensed and how the information is transduced to the nucleus to initiate the genetic response. To investigate whether the photoreceptors are involved in the response to high irradiance, we analyzed expression of ELIP1, ELIP2, APX2 and LHCB2.4 in the phyA, phyB, cry1 and cry2 photoreceptor mutants and hy5 and hyh transcription factor mutants. more...

(Submitter supplied) Transcription factors are key components of light signalling as they amplify the signal, which results in massive changes in genome-wide expression during photomorphogenesis. Three bZIP transcription factors (TFs), namely GBF1, HY5, and HYH, form heterodimers with each other and regulate photomorphogenesis in an interdependent manner. GBF1 acts as both a positive and negative regulator of photomorphogenesis, whereas HY5 and HYH mainly act as positive regulators of photomorphogenesis. more...

GBF1 acts as both a positive and negative regulator of photomorphogenesis, whereas HY5 and HYH mainly act as positive regulators of photomorphogenesis. To study the effect of HY5 and HYH on GBF1-mediated genome-wide expression, transcript profiling was performed in the gbf1 single mutant and gbf1hy5 and gbf1hyh double mutants. more...

(Submitter supplied) FAR-RED ELONGATED HYPOCOTYL 3 (FHY3) and its homolog FAR-RED IMPAIRED RESPONSE 1 (FAR1) are two transposase-derived transcription factors initially identified as the key components in phytochrome A signaling and recently shown to function in the circadian clock. However, whether FHY3 and FAR1 are involved in other processes of plant development remains largely unknown. Here, we explored chromatin immunoprecipitation-based sequencing (ChIP-seq) analysis to identify 1745 and 1171 FHY3 direct binding target genes in darkness and far-red light conditions, respectively in the Arabidopsis thaliana genome. more...
