METHOD FOR PRODUCTION OF TRANSGENIC PLANTS AND BACTERIA-RESISTANT PLANTS HAVING THE 'QUORUM SENSING' SYSTEM

摘要

The present invention is related to a method for production of transgenic plants resistant to bacteria having the Quorum sensing system and transgenic citrus plants resistant to the Huanglongbing or HLB disease. The aiiA gene, which encodes the AHL-lactonase enzyme and which is shown is SEQ ID n° 1, was used for transformation against HLB. This enzyme inactivates the acyl homoserine lactones (AHLs) produced by several phytopathogenic bacterial species, preventing this communication component (Quorum-sensing) from functioning in transgenic plants, and potentially preventing the development of the disease in the inoculated plants, We claim to have transgenic citrus trees containing the aiiA gene that are tolerante to HLB, and to other bacterial plant disease having the "quorum sensing" system.
