In response to canopy shade, plant vegetative structures elongate to gain access to light. However, the mechanism that allows a plastic transcriptional response to canopy shade light is not fully elucidated. Here we propose that the activity of PIF4, a key transcription factor in the shade signalling network, is modulated by the interplay between the BBX24 transcriptional regulator and DELLA proteins, which are negative regulators of the gibberellin (GA) signalling pathway. We show that GA-related targets are enriched among genes responsive to BBX24 under shade and that the shade-response defect in bbx24 mutants is rescued by a GA treatment that promotes DELLA degradation. BBX24 physically interacts with DELLA proteins and alleviates DELLA-mediated repression of PIF4 activity. The proposed molecular mechanism provides reversible regulation of the activity of a key transcription factor that may prove especially relevant under fluctuating light conditions. application/pdf doi:10.1038/ncomms7202 issn:2041-1723 http://ri.agro.uba.ar/greenstone3/library/collection/arti/document/2015crocco eng info:eu-repo/semantics/openAccess openAccess http://ri.agro.uba.ar/greenstone3/library/page/biblioteca#section4 Nature Communications Vol.6 art.6202 http://www.nature.com/index.html WHITE LIGHT UPREGULATION UNCLASSIFIED DRUG TRANSIENT EXPRESSION TRANSCRIPTION FACTOR BBX24 TRANSCRIPTION FACTOR STRESS SIGNALING SIGNAL TRANSDUCTION SHADE TOLERANCE SHADE SEEDLING SECONDARY METABOLISM REVERSE TRANSCRIPTION POLYMERASE CHAIN REACTION PROTEIN PROTEIN INTERACTION PROTEIN FUNCTION PROTEIN DEGRADATION PROTEIN PROMOTER REGION PLANT GROWTH PHOTOPERIODICITY PHENOTYPE NONHUMAN NICOTIANA BENTHAMIANA MOLECULAR ANALYSIS LIGHT QUALITY LIGHT EFFECT HORMONE METABOLISM HERB GLUCOCORTICOID RECEPTOR GIBBERELLIN GENOTYPE GENE REPRESSION GENE CONTROL ETHYLENE EPIDERMIS CELL DNA BINDING DELLA PROTEIN CONTROLLED STUDY CIRCADIAN RHYTHM CHROMATIN IMMUNOPRECIPITATION CELL EXPANSION BRASSINOSTEROID BIODEGRADATION AUXIN TRANSPORT AUXIN ARABIDOPSIS THALIANA ALLELE The transcriptional regulator BBX24 impairs della activity to promote shade avoidance in Arabidopsis thaliana info:eu-repo/semantics/article info:ar-repo/semantics/artículo publishedVersion info:eu-repo/semantics/publishedVersion
