Enumerating the effect of root exudation patterns and changes on soil microbiomes, and its long-term effect on planetary biogeochemical cycles that affect plant nutrient acquisition

Root exudates have been shown to play a vital role in shaping the rhizosphere microbiome, acting as both a source of nutrients for beneficial microbes and a defensive mechanism against pathogens. Our research seeks to unravel the underlying mechanisms by which root exudates mediate these interactions and influence biogeochemical cycles in soil, particularly with regard to the nitrogen and carbon cycles. Specifically, we aim to elucidate the impacts of certain nitrogen and carbon pathways on greenhouse gas emissions, including nitrous oxide and methane, as well as on soil fertility and carbon sequestration. By understanding these complex relationships, we hope to develop new strategies for sustainable agriculture that minimize environmental impacts while maximizing crop yields.

1. Investigate the influence of root exudates on the functions of the soil microbiome and their implications on biogeochemical cycles, and

2. Construct synthetic communities to establish model systems for investigating the root microbiome.

Work closely with breeders and agronomists to assess the use of smart crops to reduce agricultural pollution.
