Single-Cell/Nucleus RNA-Sequencing for Phytohormone Signaling in Plants.

Area of Science:

• Plant Biology
• Molecular Biology
• Genomics

Background:

• Phytohormones are crucial organic compounds regulating plant physiology, growth, development, nutrient transport, and survival.
• They are vital for plant adaptation to abiotic stress by modulating responses.
• Cellular gene regulation dynamics are essential for precise synthesis and control of plant hormones.

Purpose of the Study:

• To explore the gene regulatory networks underlying plant hormone biology.
• To introduce single-cell/nucleus RNA sequencing as a novel approach for studying phytohormone signaling.
• To provide a detailed methodology for applying these advanced techniques.

Main Methods:

• Utilizing single-cell RNA sequencing (scRNA-seq) and single-nucleus RNA sequencing (snRNA-seq).
• High-resolution mapping of cellular heterogeneity at the transcriptomic level.
• Investigating gene expression patterns related to phytohormone signaling pathways.

Main Results:

• Demonstrated the capability of scRNA-seq/snRNA-seq to dissect complex cellular heterogeneity in plants.
