AboutAbout the lab
Creating plants with new functions
The New Functional Plant Development Lab uses biotechnology to create plants and crops with new functions.
Its goals include edible vaccines, hairy roots for cleaning up the environment, crops that grow even in soils where plants grow poorly, and crops suited to low-input agriculture.
To develop such plants, the lab also conducts basic research to uncover how plants absorb nutrients.
Key terms
- Hairy roots
- Plant roots that branch out into fine, hair-like growths and multiply. They can be cultured to produce useful substances.
- Low-input agriculture
- Farming that reduces inputs such as fertilizers and pesticides as much as possible.
- Gene introduction
- A technique in which genes from other organisms are incorporated into a plant to give it new traits.
ResearchResearch themes
The lab uses biotechnology to create plants with new functions that can contribute broadly to society. Its work covers plants that produce useful substances, crops that can grow even in soils where it is difficult to take up metal elements essential as nutrients, and crops rich in iron and zinc.
*Illustrative imageHow plants take up minerals
The lab investigates the pathways by which plants such as rice absorb iron and zinc from the soil and transport them to leaves and seeds, as well as the molecules and genes involved. Using the genes it identifies, the lab develops crops such as those tolerant of iron deficiency.
*Illustrative imageRice and sweet potatoes rich in iron and zinc
This research aims to solve iron and zinc deficiencies, which are a major problem mainly in developing countries. Genes are introduced into rice and sweet potatoes so that they take up more iron and zinc and accumulate it in the rice grains and sweet potato tubers.
*Illustrative imageCrops that accumulate less cadmium
The lab works on creating crops that accumulate less cadmium, a toxic heavy metal that causes itai-itai disease, so that they are safer to eat.
*Illustrative image"Edible vaccines" produced in crops
In collaboration with the Global Animal Resource Science Lab, the lab is working to create "edible vaccines": crops that produce and accumulate antigen proteins that are important for acquiring immunity.
MembersFaculty
