A genetic engineering lab that investigates rice genes and puts them to use.
AboutAbout the lab
Investigating rice genes with genetic engineering
The Plant Engineering for Environmental Adaptation Lab conducts genetic engineering research on rice genes (DNA).
Main themes include production of useful proteins, improving the saccharification of rice straw, food production through cell culture, and cytoplasmic male sterility, in which pollen dies.
The lab's mascot is "Okome-chan," a character whose body is a grain of rice.
Key terms
- Cytoplasmic male sterility
- A phenomenon in which pollen dies due to interactions between the nucleus and mitochondria
- Cellular agriculture
- The idea of industrially producing agricultural products through cell culture
- Saccharification
- Breaking down cellulosic biomass, such as rice straw, into sugars

ResearchResearch themes
This lab pursues genetic engineering research on rice genes. Its themes are wide-ranging, including production of useful proteins, saccharification of rice straw, food production through cell culture, and the mechanisms of pollen development.
*Illustrative imageProducing Useful Proteins in Rice
The lab is developing ways to produce useful proteins, such as antimicrobial proteins, in rice at extremely low cost. It is also working on germination in the dark, which can greatly reduce electricity costs, and on production in rice suspension-cultured cells.
*Illustrative imageRice with Improved Straw Saccharification
Rice straw is biomass produced in large amounts every year, but it is difficult to saccharify and is hardly put to effective use. The lab uses a variety of approaches to improve the saccharification of rice straw.
*Illustrative imagePlant Cellular Agriculture: Making Food Through Cell Culture
The idea of industrially producing agricultural products through cell culture is called cellular agriculture. The lab aims to establish sustainable agriculture by maximizing the productivity of cultured plant cells and by exploring the potential of applying this to the culture of animal cells and microorganisms.
*Illustrative imageCytoplasmic Male Sterility in Rice
The lab studies cytoplasmic male sterility, in which pollen dies due to interactions between the nucleus and mitochondria, and the molecular mechanism of fertility restoration, from the perspective of plant adaptation to the environment. It also investigates genes involved in pollen development and the regulation of mitochondrial differentiation and gene expression.
