Abstract：Bacterial Fruit Blotch (BFB) of melons is one of the most serious diseases of both native and overseas water melon and muskmelon, while up to now, there is still no effective control method except strict quarantine measures. With the discovery and study progress of quorum sensing (QS), using signal interference technology to control plant bacteria diseases has been a research focus and also successfully applied. This article firstly detect signal molecules (AHL) from melons Bacterial Fruit Blotch pathogen (Acidovorax avenae subsp. citrulli) by bioassays method. Gene aiiA which can degrade AHL molecules was transformed into BFB pathogen strain NJF10. Inoculation tests showed that this transformed strain has a dramatically reduce of pathogenicity.This result lays a foundation for controlling melons Bacterial Fruit Blotch by signal interference strategy.
