TranscriptomicsTranscription profiling of Arabidopsis transgenic lines with a gibberellin non responsive DELLA protein vs control to identify DELLA protein direct targets
The aim of this study is to identify early DELLA protein-responsive genes using a Dexamethasone (DEX)-inducible system. Two transgenic lines were used: one induces the expression of a dominant, gibberellin non-responsive DELLA protein (rga-delta17); the other is a control line that carries the same ...

Transcriptomicsdella-regulation in darkness versus light-DELLAs contribute to skotomorphogenesis
rs09-09_della-dark - della-regulation in darkness versus light - Identification of DELLA-dependent downstream targets in darkness - Aim was to determine downstream target of DELLA proteins involved in skotomorphogenesis. Wt, ga1-3, ga1-3_rga_gai_rgl1_rgl2_rgl3 global seeds were sterilized, sown on M...

ProteomicsIdentification of DELLA proximitome by TurboID labeling
DELLA proteins act as transcription regulators that repress gibberellin (GA) responses and are best known for controlling the semi-dwarf crop varieties that drove the Green Revolution. DELLAs regulate gene expression primarily through protein–protein interactions with transcription factors and chrom...

ProteomicsPhosphorylation Promotes DELLA Activity by Enhancing Its Binding to Histone H2A at Target Chromatin in Arabidopsis
DELLA proteins are conserved master growth regulators that play a central role in controlling plant development in response to internal and environmental cues. DELLAs function as transcription regulators, which are recruited to target promoters by binding to transcription factors (TFs) and histone H...

ProteomicsCDK8 phosphorylation of DELLA limits Mediator recruitment in gibberellin signaling
Gibberellin (GA) promotes plant growth primarily by triggering degradation of DELLA transcription regulators, yet how DELLA activity is fine-tuned dynamically by phosphorylation independently of proteolysis remains poorly understood. Here we show that the CDK8 kinase module of the Mediator complex a...

GenomicsRGA binding sites in Arabidopsis thaliana seedlings
DELLA proteins act as hubs that relay environmental information to the multiple transcriptional circuits that control growth and development through physical interaction with transcription factors from different families. We have analyzed the presence of one DELLA protein at the Arabidopsis genome b...

TranscriptomicsTranscription profiling of Arabidopsis early gibberellin responses
The aim is to identify early gibberellin responsive genes in a gibberellin deficient strain such as ga1-3. Such genes are likely regulated by DELLA proteins which are master gibberellin repressors. DELLA proteins are rapidly degraded after gibberellin treatment, but their direct target genes still n...

TranscriptomicsExpression data of Arabidopsis seedlings in response to ARR1 or cytokinins, in the presence and absence of DELLA proteins
DELLA proteins interact with ARR1 and modulate its activity. We have investigated the effect of DELLA proteins on transcriptional regulation by ARR1 A dominant hyperactive allele of ARR1 was induced with dexamethasone in seedlings preincubated with paclobutrazol (allowing DELLA acummulation) or pacl...
