水稻白叶枯病是使水稻遭受重大损失的主要病害。曾有利用白叶枯病原菌胞外多糖（ＥＰＳ）和白叶枯病原菌弱毒株诱导水稻对白叶枯病害抗病性的报道。但有关应用植物促生细菌（ＰｌａｎｔＧｒｏｗｔｈＰｒｏｍｏｔｉｎｇＢａｃｔｅｒｉａ，ＰＧＰＢ）诱导水稻对白叶枯病害抗性 Rice bacterial leaf blight is a major disease that causes heavy losses to rice. There have been reports of the resistance of rice to bacterial leaf blight induced by the extracellular polysaccharide (EPS) of Bacterial leaf blight and the attenuated strain of Bacterial blight. However, the application of Plant Growth-promoting Bacteria (PGPB) to induce rice resistance to bacterial leaf blight
