Development of McH-lpr/lpr-RA1 mouse, a study model that spontaneously develops severe autoimmune arthritis, vasculitis, and sialadenitis

 
 
NEXT
PREV
特徴・独自性
  • McH/lpr-RA1 mice are recombinant congenic mice descended from MRL/lpr and C3H/lpr mice and develop arthritis, vasculitis, and sialadenitis with high frequency and severity, with severe pannus formation similar to rheumatoid arthritis, polyarteritis nodosa, and Sjogren's syndrome. On the other hand, McH/lpr-RA1 mice do not develop systemic lymphadenopathy and severe nephritis as seen in MRL/lpr mice, so they are easy to breed and maintain and can be used for long-term drug administration experiments.

Improvement of Seed Production by Using Reproductive Trait in Crops, Especially, Rice and Cruciferous Crops

 
 
 
NEXT
PREV
概要

The recent spate of extreme weather events is threatening to reduce crop seed and fruit production. We have identified a catalog of genes that respond under low and high temperature stress, and will construct a system that enables production under temperature stress through genome editing and other methods.

従来技術との比較

In addition to conventionally used genetic recombination methods, genome editing technology has made it possible to modify genes that can be used for practical purposes.

特徴・独自性
  • Crops are important for food, environment recovery, energy production, and amenity activity for human being. For improvement of crop seed production, the breeding of crops having environmental stress, is important. Especially the developmental stage from pollination to fertilization is quite weak for these environmental stresses. Thus, by breeding of reproductive trait, we will establish the high productivity and quality of crop seeds. From our research, we found several stress-tolerant genes. We already started the research by both basic and applied level.
実用化イメージ

For application, we evaluated by taking prize for application in 2001. And our basic data has been published in international Journal, "Nature" and "Science". If anyone is interested in these genes, we hope to conduct to collaborative research for establishing the useful breeding lines.

Methods to Restore Strelity of Gramineous Plants under High- and Low-Temperature Stress Conditions

NEXT
PREV
特徴・独自性
  • Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High-temperature injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to high temperature. Oppositely, grain yields in rice plants are often reduced by exposure to low temperature. Unexpected climate change, such as abnormally hot or cool summer temperatures, have occurred repeatedly during recent years. This method indicates that an appropriate use of specific phytohormones, such as auxin and GA, may promote stress tolerance and adaptation to abiotic stresses.
実用化イメージ

These potentially novel functions of the classical phytohormones will be important sustainable agriculture in the face of global climate change.

Generation of Rice Plants Suitable for Biofuel Production

 
 
NEXT
PREV
特徴・独自性
  • To generate a rice plant suitable for efficient biofuel production from its straw, we examined effects of overexpression of cellulase on saccharification of straw. The transgenic plant constitutively overexpressing cellulase showed enhanced saccharification, but various physiological and morphological abnormalities were also observed. To overcome this problem, a senescence-inducible promoter was used to express the cellulase. The plants successfully avoided the problem and showed enhanced saccharification after senescence.
実用化イメージ

Rice straw will be an efficient material for biofuel production. This method can be applied to other plants. In combination with highly engineered microorganisms for saccharification and fermentation, this method will contribute to efficient production of biofuels.

Molecular studies on new resources for hybrid rice breeding

 
 
 
NEXT
PREV
特徴・独自性
  • F1 hybrid breeding is one of the most advanced techniques for production of cultivars with higher yield and desirable traits of both parents. Most of hybrid rice utilize cytoplasmic male sterility (CMS) and fertility restoration system. We develop a Tohoku University-original CW-type CMS and fertility restorer line and study their molecular mechanism. The CW-type cytoplasm enables indica rice cultivars to be CMS, which could not be achieved by other known cytoplasm.
実用化イメージ

Hybrid rice has an average 30% yield advantage over inbred lines, and is cultivated on 13% of the world rice fields. Our study provides a new and original resource for hybrid rice breeding for globalization of rice industry.

Room temperature bonding using thin metal films (Atomic Diffusion Bonding)

 
 
 
NEXT
PREV
特徴・独自性
  • Atomic diffusion bonding of two flat wafers with thin metal films is a promising process to achieve wafer bonding at room temperature. High surface energies of metal films and a large atomic diffusion coefficient at the grain boundaries and film surfaces enable bonding at room temperature without unusually high loading pressure. This technique, which enables bonding of any mirror-polished wafer, is gaining wider use for fabricating optical and electrical devices. Moreover, bonding of mirror polished metals and polymer sheets can be achieved, which further extends the application of this bonding technique.
