Molecular studies on new resources for hybrid rice breeding

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.

特徴・独自性
  • My research area is mainly phenomenology, philosophy of technology, and applied ethics (engineering ethics etc.). Technological Artifacts mediate human activities. So designing artifacts is in itself an ethical behavior. Analysing the ontological structure of the artifacts, describing the epistemological propcess of desingning activities, evaluating the social and ethical influence of artifacts are main issues in philosophy of technology. On the basis of such philosophical investigations, we can develope ethical studies concerining how engineerss, companies can recognize ethical issues in a networks of meanings , how they can make ethical decision among engineers and users.
実用化イメージ

I hope to conduct cooperative research on ethical education of engineers, as well as on human-machine interaction.

特徴・独自性
  • The difficulties of introducing robot systems in production line are maintenance of environment and teaching of robot motion. Environ recognition and motion teaching using vision system will greatly improve the difficulties. However, calibration of vision-robot system is tedious and troublesome. Feedback control using vision sensor information will allow robustness against environment and teach by showing. This technique is called visual servo.
実用化イメージ

Visual servo will allow flexible camera setting, calibration-less system setting, and easy teaching.

High Sensitivity Radioactivity Measurement at Ultra-Low Radioactivity Environment

 
NEXT
PREV
特徴・独自性
  • Research Center for Neutrino Science established ultra-low radioactivity environment (trillion times lower than natural environment) with 1200 cubic-meter organic scintillator detector at 1000m underground where very stable temperature/humidity and low vibration are maintained. We are pursuing high sensitivity measurements, especially neutrino observation, and are also developing purification system for ultra-low radioactivity and high performance radioactivity detectors.
実用化イメージ

The established ultra-low radioactivity environment is suitable for rare phenomena study and is also applicable for high sensitivity radio-impurity measurement. It may also apply to investigation of biological influence of low radioactivity irradiation. The other applications such as neutrino detection technique for monitoring nuclear reactors and medical use of high sensitivity radioactivity detectors may also be considered.
