Understanding the regulation mechanism of oxygen transportation system for crop waterlogging tolerance.

在日本，大豆、小麦和大麦种植在用于水稻种植的稻田中。因此，水涝是种植这些大田作物的最大问题之一。然而，大部分耐涝机制仍然无法解释。径向氧损失屏障的形成是植物在淹水土壤条件下生存的有效适应特征之一。到目前为止，还没有发现它可以调节ROL屏障的形成。在此，我们确定了REDUCED CULM NUMBER1基因部分调控水稻对ROL形成屏障。

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.
