The lab aims for sustainable agriculture by transferring the resilience of wild rice to cultivated rice.
AboutAbout the lab
Sustainable agriculture, powered by the strength of wild rice
The Ohmori Lab studies how to confer the resilience of wild rice on cultivated rice.
Chemical fertilizers have greatly increased humanity's food productivity, but their heavy use causes groundwater pollution, eutrophication of marine waters, and global warming.
In nature, wild rice, which refers to relatives of rice that have not been domesticated, survives in harsh environments.
Using an approach called multi-omics analysis, the lab investigates this strength and develops rice that grows well with less fertilizer and rice that is tolerant of temperature and light stress.
Key terms
- Wild rice
- Relatives of rice that have not been domesticated. They survive in harsh natural environments.
- Multi-omics
- An approach that measures many types of biological information, such as genomes and metabolites, and analyzes them together.
- Field informatics
- A field that applies large amounts of data collected from fields by drones and environmental sensors to breeding and production.

ResearchResearch themes
The lab works on field informatics, which makes use of big data collected from entire fields by drones and environmental sensors, together with omics information on crops. By conferring the resilience of wild rice on cultivated rice, the lab aims to realize a sustainable food production system that does not depend on chemical fertilizers.
*Illustrative imageBringing the Resilience of Wild Rice to Cultivated Rice
The lab uses multi-omics analysis to investigate the resilience of wild rice and studies how to confer it on cultivated rice. So far, the lab has developed rice that grows well with less fertilizer and rice that is tolerant of temperature and light stress.
*Illustrative imageRice Production with Less Chemical Fertilizer
The lab improves Koshihikari, the most widely produced rice variety in Japan, to develop rice with high yield potential even with less chemical fertilizer. In cooperation with agricultural experiment stations and farmers, the lab conducts field demonstration trials of rice production without chemical fertilizers.
