Genome wide BZR1 binding site analysis in Arabidopsis

ABSTRACT: BR induces rapid dephosphorylation and nuclear localization of BZR1 through a cascade of signaling events thus regulates BR-responsive gene expression and plant development. We use chromatin-immunoprecipitation microarray (ChIP-chip) experiments identified about 2200 high confidence BZR1 binding sites, which includes all previous known binding regions. The binding sites are distributed throughout the genome but are rare in the centromere regions, which is similar to the distribution of expressed genes. The binding sites were substantially enriched in the 5’ and 3’ intergenic regions compared to the transcribed regions of genes. Combining with transcription profilling of BR regulated genes generated 953 BR regulated BZR1 targets.

Brassinosteroid mutant (bzr1-1D and det2) analysis

Project description:Brassinosteroid (BR) homeostasis and signaling are crucial for normal growth and development of plants. BR signaling through cell-surface receptor kinases and intracellular components leads to dephosphorylation and accumulation of the nuclear protein BZR1. How BR signaling regulates gene expression, however, remains unknown. Here we show that BZR1 is a transcriptional repressor that has a previously unknown DNA binding domain and binds directly to the promoters of feedback-regulated BR biosynthetic genes. To identify additional BZR1-regulated genes and to understand the BR-regulated transcriptional pathways, we examined the effects of bzr1-1D and det2 mutations on the expression of BR-regulated genes by using the Arabidopsis full-genome oligo microarray (Affymetrix). Microarray analyses identified additional potential targets of BZR1 and illustrated, together with physiological studies, that BZR1 coordinates BR homeostasis and signaling by playing dual roles in regulating BR biosynthesis and downstream growth responses.

Interaction between BZR1 and PIF4 integrates brassinosteroid and environmental responses [ChIP-seq]

Project description:Plant growth is coordinately regulated by environmental and hormonal signals. Brassinosteroid (BR) plays essential roles in growth regulation by light and temperature, but the interactions between BR and these environmental signals remain poorly understood at the molecular level. Here, we show that direct interaction between the dark- and heat-activated transcription factor phytochrome-interacting factor4 (PIF4) and the BR-activated transcription factor BZR1 integrates the hormonal and environmental signals. BZR1 and PIF4 interact with each other in vitro and in vivo, bind to nearly two thousand common target genes, and synergistically regulate many of these target genes, including the PRE family HLH factors required for promoting cell elongation. Genetic analysis indicates that BZR1 and PIFs are interdependent in promoting cell elongation in response to BR, darkness, or heat. These results show that the BZR1-PIF4 interaction controls a core transcription network, allowing plant growth co-regulation by the steroid and environmental signals. Genome-wide identification of PIF4 binding sites in etiolated Arabidopsis seedlings.

Overexpression of BEH2 regulates a much broader range of gene expression than BZR1

Project description:Based on the distinct phenotypes of BEH2-overexpressing plants, we compared the functional roles of BZR1 and BEH2. The BEH2 is a stronger transcriptional regulator of BR-responsive gene expression than BZR1. It appears that BEH2 also regulates gene expression in a BR-independent manner.

Expression data from dark-grown BR double mutant bzr1-1D;bri1-116, single mutant bri1-116, and wildtype

Project description:Molecular genetic analyses support a central role of BZR1 in Brassinosteroid (BR) regulation of plant development. The dominant bzr1-1D mutation, which stabilizes the BZR1 protein, completely suppresses the de-etiolated phenotype of the null bri1-116 mutant grown in the dark. Using microarray analysis, we identified genes differentially expressed in bri1-116 compared to wild type and genes differentially expressed in the bzr1-1D;bri1-116 double mutant compared to the bri1-116 single mutant. Consistent with the phenotypic suppression of bri1-116 by bzr1-1D, about 80% of the genes affected in bri1-116 were affected oppositely by bzr1-1D

Brassinosteroid, gibberellin, and phytochrome impinge on a common transcription module in Arabidopsis

Project description:Brassinosteroid (BR) and gibberellin (GA) promote many similar developmental responses in plants; but their relationship remains unclear. Here we show that BR and GA act interdependently through a direct interaction between the BR-activated BZR1 and GAinactivated DELLA transcription regulators. GA promotion of cell elongation required BR signaling, whereas BR or active BZR1 can suppresssed the GA-deficient dwarf phenotype. DELLAs directly interacted with BZR1 and inhibited BZR1-DNA binding both in vitro and in vivo. Genome-wide analysis defined a BZR1-dependent GA-regulated transcriptome, which is enriched with light-regulated genes and genes involved in cell wall synthesis and photosynthesis/chloroplast. GA promotion of hypocotyl elongation requires both BZR1 and the phytochrome interacting factors (PIFs), as well as their common downstream targets PREs. The results demonstrate that GA releases DELLA-mediated inhibition of BZR1, and that the DELLA-BZR1-PIF4 interaction defines a core transcription module that mediates coordinated growth regulation by GA, BR and light signals.
