The root-knot nematode Meloidogyne chitwoodi is a pest that affects potato production in the Pacific Northwest of the United States. Here, to develop new strategies against M. chitwoodi infection of potato, we engineered Bacillus subtilis to secrete the plant-defence elicitor peptide StPep1. Pre-treatment of potato roots with the bacteria secreting StPep1 substantially reduced root galling, indicating that a bacterial secretion of a plant elicitor is an effective strategy for plant protection.

使用细菌传递的植物防御诱导剂增强马铃薯对根结线虫的抗性。

该根结线虫南方chitwoodi是影响在美国太平洋西北地区马铃薯生产害虫。在这里，为了开发针对马铃薯M. chitwoodi感染的新策略，我们设计了枯草芽孢杆菌来分泌植物防御诱导肽StPep1。用分泌StPep1的细菌对马铃薯根进行预处理可大大减少根root，这表明植物引发剂的细菌分泌是植物保护的有效策略。
