TranscriptomicsTranscription profiling of Arabidopsis steroid inducible RGA expressor transgenic to identify RGA downstream genes
To understand the transcriptional program controlled by RGA, we took advantage of a functional steroid-inducible RGA proteins system in combination with microarray analysis to identify RGA target genes. Experiment Overall Design: We firstly compared the transcriptomes in ga1-3rgargl2RGA-GR infloresc...

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...

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...

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 ...

TranscriptomicsGlobal gene expression profiles of Oryza sativa wild type Nipponbare and mutant coi1-13
To reveal the underlying molecular mechanism of jasmonate inhibits gibberellins signaling in rice, we performed transcriptional profiling of wild type nipponbare and mutant coi1-13 plants on a global scale using the Affymetrix GeneChip Rice Genome Array Rice young uppermost internodes were harvested...

TranscriptomicsAtbZIP16 integrates light and hormone signaling pathways to regulate Arabidopsis early seedling development
In response to environmental light signals, transcriptomic adjustment plays an important role in Arabidopsis seed germination and seedling development. G-box cis-element is commonly present in promoters of genes positively or negatively responding to the light signal. For the pursuit of additional t...
