Plant metabolism: Zoom in to the single-cell level

Area of Science:

• Plant biology
• Metabolomics
• Genomics

Background:

• Plant specialized metabolism is complex and cell-type specific.
• Previous methods for metabolite localization were limited.
• Understanding metabolite accumulation is key to function and regulation.

Purpose of the Study:

• To review advances in visualizing and quantifying plant metabolites and gene expression at cellular resolution.
• To highlight the role of specialized cell types in plant metabolism.
• To emphasize the importance of multi-omics approaches.

Main Methods:

• Mass spectrometry imaging
• Single-cell transcriptomics
• Multi-omics integration

Main Results:

• Cell type- and organ-specific metabolite accumulation patterns identified.
• Underlying transcriptional and chromatin regulatory networks elucidated.
• Case studies demonstrate the role of rare cell types in specialized metabolite biosynthesis.

Conclusions:

• Advanced imaging and multi-omics enable high-resolution understanding of plant metabolism.
• Spatiotemporal regulation is crucial for specialized metabolite biosynthesis.
• Future research will drive precise pathway discovery and metabolic engineering applications.
