Exploring the plant microbiome: A pathway to climate-smart crops

Area of Science:

• Agricultural Science
• Environmental Science
• Microbiology

Background:

• The Green Revolution increased crop yields but led to environmental issues like pollution and greenhouse gas emissions.
• Sustainable agriculture requires new strategies, and manipulating plant-associated microbes is a promising, yet overlooked, approach.
• Rhizosphere microbiome manipulation was not a focus during crop domestication.

Purpose of the Study:

• To propose a framework for developing climate-smart crops by modulating plant microbiomes.
• To enhance crop yield and reduce environmental impacts through microbiome engineering.
• To integrate plant genetics, root exudates, and microbial communities for sustainable agriculture.

Main Methods:

• Developing a framework that integrates plant genotype, root exudates, and soil microbes.
• Focusing on optimizing nutrient cycling, enhancing stress resilience, and promoting carbon sequestration.
• Incorporating unselected ecological traits into crop breeding programs.

Main Results:

• Modulating rhizosphere microbiomes offers a pathway to sustainable agriculture.
• Climate-smart crops can be developed to improve yield and mitigate environmental harm.
• The proposed framework highlights the interconnectedness of plant genetics and ecosystem functions.

Conclusions:

• Integrating plant genetics with microbiome engineering is key to sustainable agriculture.
• Developing climate-smart crops can address food security and environmental concerns.
• Understanding the plant-microbe-environment nexus is crucial for future agricultural innovation.
