Research Summary

Masatomo  Kobayashi(Ph.D.)

Plant science is important for the production of food and useful materials as well as the preservation of the global environment. Since April 2002, the Experimental Plant Division has been selected as a national core institution of the Arabidopsis, plant cultured cells and DNA resources by the Japanese government. The aim of the laboratory is the collection, preservation and distribution of seeds, plant DNA materials and plant cultured cells. A model plant, Arabidopsis thaliana is the major origin of our resources. Development of novel technologies for the preservation and characterization of wild-type Arabidopsis and plant cultured cells is carried out. Training course is operated to distribute the technologies. In addition, we intend to establish a research platform of Brachypodium distachyon, a novel experimental plant of monocot, to contribute crop breeding research.
