Plant microbiomes are crucial for nutrient acquisition, involving complex signaling and sensing. Harnessing these plant-microbial interactions offers sustainable nutrient solutions for ecosystems and food security.
Area of Science:
- Plant biology
- Microbiology
- Ecology
Background:
- Plants and their associated microbiomes have co-evolved over millennia.
- Microbiomes play a vital role in plant nutrient acquisition through intricate signaling and sensing mechanisms.
Purpose of the Study:
- To synthesize recent advancements in microbe-facilitated plant nutrient uptake.
- To evaluate opportunities for harnessing plant microbiomes for sustainable nutrient supply in ecosystems.
Main Methods:
- Review of molecular, physiological, and eco-evolutionary mechanisms.
- Focus on plant-microbial communication and metabolic pathways.
Main Results:
- Complex associations underpin nutrient uptake.
- Potential exists to utilize microbiomes for sustainable nutrient provision.
Conclusions:
- Knowledge gaps hinder progress; an integrated, eco-evolutionary framework is needed.
- Advancing fundamental science with analytical approaches is key for microbiome-informed tools to enhance plant nutrition, food security, and sustainability.
