摘要: 烟草病毒可侵染危害烟草、番茄、辣椒和土豆等多种作物导致病毒病发生,是生产上难以防治的病害。为了探索蛋白激发子PeaT1与井冈霉素混合使用对烟草病毒病防治的最佳混配比例,本研究选用3-7片真叶的本生烟(Nicotiana benthamiana cv. Huangmiaoyu),分别喷施清水、井冈霉素、蛋白激发子PeaT1及蛋白激发子PeaT1-井冈霉素复合制剂,采用摩擦接种的方式接种TMV-GFP病毒,在紫外光下观察病毒的侵染情况。结果表明,喷施了井冈霉素和蛋白激发子复合制剂的本生烟对TMV的抗性较单剂具有增效作用,其中蛋白激发子PeaT1-井冈霉素按3:4混配的性价比最高,共毒系数达到157.64,相对防效为73.39%。这说明井冈霉素和蛋白激发子PeaT1都能使烟草产生对TMV的系统获得抗性,而其复合制剂更有着叠加效应。

Abstract: Tobacco virus infects tobacco,tomatoes,peppers,potatoes,and other crops,causing a variety of crop diseases that are difficult to control during production. To explore the optimal mixed proportion of protein elicitor PeaT1 and Jinggangmycin to defense tobacco virus disease,this study chosen Nicotiana benthamiana cv. Huangmiaoyu having 3 to 7 leaves,respectively by spraying water,Jinggangmycin,and combination of PeaT1 and PeaT1-Jinggangmycin. Virus TMV-GFP was inoculated by the way of friction,and viral infection situation was observed under UV light. The results showed that the combination of Jinggangmycin mixed with PeaT1 had better synergism than using single one;PeaT1:Jinggangmycin at 3:4 mixed ratio had the most cost-efficient,and cotoxicity coefficient reached 157.64,the relative control effect reached 73.39%. Therefore,we thought that Jinggangmycin and PeaT1 both generated tobacco resistance against TMV,and their combination had synergetic effect.
