Summary
Brassinosteroid (BR) hormone signaling is crucial for plant development. Time-series single-cell RNA sequencing identified the cortex as a key site for BR gene regulation during cell phase transitions.
Area of Science:
- Plant biology
- Molecular biology
- Genetics
Background:
- Phytohormone signaling pathways regulate critical plant growth and developmental processes.
- Single-cell RNA sequencing (scRNA-seq) offers high resolution for dissecting complex gene regulatory networks.
Purpose of the Study:
- To investigate the role of brassinosteroid (BR) signaling in plant development.
- To identify key tissues and regulatory networks involved in BR-mediated gene expression using scRNA-seq.
Main Methods:
- Utilized time-series single-cell RNA sequencing (scRNA-seq) on plant tissues.
- Analyzed gene expression patterns to map hormone-mediated regulatory networks.
Main Results:
- Identified the cortex as a primary tissue for brassinosteroid (BR)-mediated gene expression.
- Revealed a specific signaling network active during cell phase transition in response to BRs.
Conclusions:
- The cortex plays a significant role in brassinosteroid (BR) signaling.
- Time-series scRNA-seq is a powerful tool for uncovering spatiotemporal gene regulatory mechanisms in plants.

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

8.2K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...
