| Research Abstract |
In Japan, soybean, wheat and barley are grown in the paddy filed using for rice cultivation. Thus, waterlogging is one of the biggest problems for the cultivation of these filed crops. However, the most part of mechanism of waterlogging tolerance remains unexplained. Formation of barrier to Radial Oxygen Loss (ROL) is one of effective adaption trait for survival in the waterlogged soil conditions. So far, it was not identified to regulate formation of barrier to ROL. Here, we identified that REDUCED CULM NUMBER1 gene partly regulates to form barrier to ROL in rice.
