Nutrients guide plant-microbe interactions by acting as spatial signals. New single-cell technologies reveal how these nutrient cues coordinate cellular responses at the plant-microbe interface for a mechanistic understanding.
Area of Science:
- Plant-microbe interactions
- Nutrient signaling
- Spatial biology
Background:
- Plant-microbe interactions are spatially organized.
- Nutrients act as both resources and spatial signals in these interactions.
- Cellular nutrient perception and signaling in plants and microbes create heterogeneous interaction niches.
Purpose of the Study:
- To integrate current understanding of nutrient-guided plant and microbial responses.
- To highlight emerging technologies for studying these interactions at cellular resolution.
- To introduce a cell-state framework for interpreting plant-microbe interactions.
Main Methods:
- Review of current understanding of nutrient-guided plant and microbial responses.
- Highlighting advances in single-cell, spatial omics, and nutrient mapping.
- Introduction of a cell-state framework.
Main Results:
- Nutrient perception and signaling are spatially patterned in plants and microbes.
- Local nutrient conditions influence microbial colonization, metabolism, and function.
- Emerging technologies enable cellular-resolution analysis of these processes.
Conclusions:
- Plant-microbe interactions can be viewed as emergent properties of spatially coupled cellular responses.
- Local chemical environments coordinate cellular responses at the plant-microbe interface.
- A cell-state framework provides a foundation for mechanistic and predictive understanding.
