Synthetic microbial communities for engineering climate-smart biofertilizers

Area of Science:

• Agricultural Science
• Microbiology
• Ecology

Background:

• Climate change significantly destabilizes global agricultural productivity through extreme weather events.
• Current climate-smart agriculture (CSA) strategies primarily focus on plant genetics and agronomic inputs.
• The adaptive potential of the crop microbiome remains largely underexplored in CSA frameworks.

Purpose of the Study:

• To examine the agricultural application of synthetic microbial communities (SynComs) within the crop holobiont concept.
• To explore how SynComs can enhance crop resilience and phenotypic plasticity under climate stress.
• To propose a roadmap for integrating synthetic ecological engineering in crop microbiology for CSA.

Main Methods:

• Investigating the crop holobiont as an integrated plant-microbe system.
• Identifying stress-adapted microbes from pioneer plants in extreme environments.
• Assembling SynComs from these microbes for agricultural applications.

Main Results:

• SynComs can function as nutrient suppliers and physiological modulators for crops.
• Microbial communities enhance crop phenotypic plasticity, improving stress tolerance.
• Pioneer plant microbiomes offer a strategic resource for developing climate-resilient agriculture.

Conclusions:

• The crop holobiont concept provides a novel framework for advancing CSA.
• Synthetic microbial communities are a promising tool for enhancing agricultural adaptation to climate change.
• Integrating synthetic ecological engineering into crop microbiology is crucial for future agricultural sustainability.
