Federal Grant Award Summary

Michigan State University received a $649,998 Project Grant from the Institute of Food Production and Sustainability under the Agriculture and Food Research Initiative (AFRI, CFDA 10.310) with an award date of February 15, 2026, and completion date of February 14, 2030. The grant supports fundamental research to identify and characterize the mechanisms of action of the OSRSK1 protein in rice plants, with the objective of enabling rice cultivation in phosphorus-deficient soils. The research team will investigate three primary questions: how OSRSK1 is activated and deactivated in response to low-phosphorus conditions, how OSRSK1 expression levels are regulated within rice plants, and which regulatory genes facilitate this adaptive response. Deliverables will include peer-reviewed scientific publications and research findings that advance understanding of phosphorus-stress tolerance mechanisms in rice.

This research directly supports AFRI's Plant Health and Production priority area by addressing a critical agricultural challenge: reducing fertilizer dependency while maintaining crop productivity. By elucidating the genetic and molecular pathways underlying rice phosphorus-use efficiency, the project aims to provide a scientific foundation for developing rice varieties with improved nutrient-use efficiency. Such innovations could reduce environmental impacts associated with phosphorus fertilizer application while enhancing food security through more sustainable agricultural practices.
