AI Technical Summary
Technical Problem
In the existing technology, chemical methods for controlling bacterial wilt of plants have environmental pollution problems, while biological control methods are prone to pathogen resistance mutations. There is a lack of efficient biological control methods for bacterial wilt of plants in the existing technology.
Method used
A strain of Pseudomonas flatus QE6 was used to inhibit the pathogenicity of Raulella solanaceae by degrading methyl 3-hydroxypalmitate (3-OH PAME), a quorum sensing signal molecule for bacterial wilt, thereby controlling bacterial wilt in plants.
Benefits of technology
It effectively prevents bacterial wilt of plants, avoids resistance mutations in pathogens, and achieves green and long-lasting disease control.

Abstract
本发明提供了扁平假单胞菌(Pseudomonas procumbens sp.nov.)QE6菌株及其在植物青枯病中的应用。所述扁平假单胞菌QE6菌株于2023年10月13日保藏于广东省微生物菌种保藏中心，保藏编号为GDMCC No：63880，保藏地址为：广州市先烈中路100号大院59号楼5楼。该扁平假单胞菌QE6菌株可降解茄科劳尔氏菌产生的3‑OH PAME信号分子，进而有效防治木麻黄青枯病与花生青枯病，因此，扁平假单胞菌QE6菌株适用于制备防治植物青枯病的制剂。
