Drought represents a major threat to food security. Mechanistic data describing plant responses to drought have been studied extensively and genes conferring drought resistance have been introduced into crop plants. However, plants with enhanced drought resistance usually display lower growth, hi...

This study presents an untargeted LC-MS-based metabolomics dataset generated from leaves of Quercus glauca subjected to drought stress and exogenous brassinosteroid treatment. Leaf samples were collected at multiple time points under control, drought, and drought plus brassinosteroid conditions t...

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 ...
ORGANISM(S): Arabidopsis thaliana 
We found that auxin stimulates gene expression of DWF4, which encodes a rate-dertermining step in brassinosteroid biosynthesis pathways. This increased gene expressioin subsequently led to elevation of the biosynthetic flux in Arabidopsis roots. To determine the list of genes that are regulated by a...

This SuperSeries is composed of the following subset Series: GSE35315: Interaction between BZR1 and PIF4 integrates brassinosteroid and environmental responses [ChIP-seq] GSE37159: Interaction between BZR1 and PIF4 integrates brassinosteroid and environmental responses [RNA-seq] Refer to individual ...

Analysis of brassinosteroid (BR) and auxin effects on gene expression in Arabidopsis roots. Our genomic results indicate that BR and auxin induce largely opposite gene expression responses in primary roots. RNA-Seq for 7-day-old Arabidopsis Col-0, dwf4, bri1-116, and bri1-116;bzr1-1D roots grown on ...

We describe a new mutant allele of the ACTIN2 gene with enhanced actin dynamics, displaying a broad array of twisting and bending phenotypes that resemble BR-treated plants. Moreover, auxin transcriptional regulation is enhanced on the mutant background, supporting the idea that shaping actin filame...

The mechanisms ensuring balanced growth remain a critical question in developmental biology. In plants, this balance relies on spatiotemporal integration of hormonal signaling pathways, but the understanding of the precise contribution of each hormone is just beginning to take form. Brassinosteroid ...

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; express...
