Efficient endogenous Burkholderia gladioli NSPE25 and application thereof
Technical Field
The invention belongs to the technical field of biological control of plant diseases, and particularly relates to a high-efficiency endogenous Burkholderia gladioli NSPE25 and application thereof.
Background
Guava (Psidium guajava) is a special fruit with edible nutrition and medicinal efficacy, is planted in China Guangdong, Guangxi, Fujian, Hainan, Taiwan and other provinces, and has high economic value. Guava scab caused by Pestalotiopsis sp, seriously affects the quality and healthy production of guavas (Linzheng faithful, Zea's terfene. guavas disease (II.) agricultural world, 1996,159: 54-56.). Guava scab mainly damages fruits, and most of the scab is round and slightly convex. The surface of the scab is rough and has cracks, such as scabs; in the middle of the latter lesions, small black spots often appear (Keith L M, Vel' asquez ME, Zee FT, Identification and characterization of Pestalotiopsis sp. occupying scab disease of guava, Psidium guajava, in Hawaii. plant disease.2006,90: 16-23.). In the production process, the prevention and control of guava scab are mainly based on the prevention and control of medicaments, but the safety problem of fruits and vegetables caused by pesticide residues is more and more concerned by the general public.
The endophyte does not infect host plants or cause obvious disease symptoms, and lives in tissues and organs of healthy plants at a certain stage or whole stage in the life history, and is in reciprocal symbiosis with the host plants. The endophyte has important functions of resisting (plant diseases and insect pests, adversity and heavy metal) stress, promoting growth, inducing resistance and the like of host plants. Few reports are reported about the biological control of guava diseases, and the mining, the development and the utilization of endophyte resources have important significance for the safe and effective control of the guava diseases.
Although there are reports on biological control of Pestalotiopsis sp, for example, chinese patent CN112662578A published in 2021 at 4/16 discloses that paenibacillus polymyxa DX32 can effectively inhibit phytopathogenic fungi of Pestalotiopsis, but the strain has strong individual specificity and is greatly influenced by the environment as a pure culture.
