| Research Abstract |
It was appeared that a resistance to the sheath blight disease (SBD) was resulted from a regulation in the carbon distribution named as a carbon crossroad inthe glycolysis, from the glycolysis to sucrose, starch and phenylpropanoid metabolisms, and also suggested that elucidations on the regulating mechanism become the next target ofmetabolic engineering studies to develop the SBD resistance. Also, the existence of twoQTLs in the SBD resistant rice line showed a possibility to improve resistant varieties. In addition, the gene linkage between SBD resistance and a heterosis of the yield in ourimproved SBD resistant rice line suggests a possibility to achieve both of the SBD resistance and the high yield.
