Cubense race 4 (FOC4), and the expression levels more than comparison. The physiological result was identical with that of molecular biology research, meanwhile, resembling the research results of other plants. It demonstrated that the PAL enzyme played a key role in resisting banana wilt.

cubense race 4 (FOC4)茎中 PAL 表达的变化，结果显示茎中 PAL 活性呈规律性变化，且均高于同期对照，与其它植物相关研究结果类似，表明 PAL 与香蕉抗枯萎病密切相关。

The strain BEB2 of endophytic Bacillus isolated from banana was identified as Bacillus subtilis according to its homology analysis of 16S rDNA sequence. The temperature, pH and medium had a significant impact to the inhibition of BEB2 to the banana wilt disease.

利用聚合酶链式反应方法对细菌BEB2做进一步的分子鉴定，并研究不同温度、pH值和培养基下BEB2发酵液对香蕉枯萎病菌生长的抑制能力，以及应用BEB2对香蕉枯萎病进行防治测试。

The inhibitory effect was strongest in King B2 medium, the optimum temperature for the highest antimicrobial activity was 33℃, and the optimal pH9.0. In the antagonistic test of BEB2 to the banana wilt disease, the inhibition was obvious with different in vitro methods, and the control effect of pot experiment was good.

结果发现，香蕉内生拮抗细菌BEB2为枯草芽孢杆菌；不同温度、pH值和培养基下的BEB2发酵液对香蕉枯萎病菌生长的抑制能力具显著差异，在King B2培养基上抑菌作用最强，最适抑菌温度为32 ℃，最适抑菌pH值为9.0。
