Summary
Spatial transcriptomics reveals gene expression is organized by position in plants, impacting development and physiology. Future research aims for single-cell resolution to understand plant function and improve crops.
Area of Science:
- Plant Biology
- Genomics
- Developmental Biology
Background:
- Bulk and dissociation-based transcriptomics lose spatial context.
- Spatial transcriptomics restores this lost spatial information.
- Gene expression is cell-type specific and positionally organized.
Purpose of the Study:
- To review recent advances in plant spatial transcriptomics.
- To highlight the role of spatial gene expression in plant development and physiology.
- To identify limitations and future directions in the field.
Main Methods:
- Synthesis of recent studies across diverse plant species and tissues.
- Analysis of gene expression patterns in meristems, vascular tissues, floral organs, seeds, grains, and during plant-microbe interactions.
- Review of studies on photosynthesis, drought adaptation, and regeneration.
Main Results:
- Gene expression is tightly organized by position within plant organs and developmental niches.
- Spatially segregated programs control growth, differentiation, nutrient transport, dormancy, embryogenesis, symbiosis, immunity, and stress responses.
- Spatial gene expression is a fundamental organizing principle in plants.
Conclusions:
- Spatial transcriptomics is revolutionizing plant biology by linking gene expression to biological function.
- Limitations include restricted resolution, computational reliance, and validation gaps.
- Future work requires single-cell resolution, multi-omics integration, and functional validation for mechanistic understanding and crop improvement.
