Disease Resistance Induction in Rice by Inoculation with Endophytic Bacteria Strain REB01
This work is supported by 15TD0026 of the scientific research fund of the Sichuan provincial education department.
Endophytic bacteria strain REB01 was isolated from the seeds of rice and antagonized against Rhizoctonia solani Kuhn caused rice sheath blight. The purpose of the research outlined in this paper was to investigate if strain REB01 can induce resistance of rice sheath blight. The methods for measuring the induced resistance of strain REB01 to rice sheath blight was by measuring the change of the activities of defense enzymes, peroxidase (POD) and polyphenol oxidase (PPO) and the contents of pathogenesisrelated biochemicals, malondialdehyde (MDA) in rice leaves inoculation with REB01, R. solan and the control in pot tests. This experiment results indicated the activity of POD and PPO and the Content of MDA in rice leaves was very significantly affected by endophytic bacteria strain REB01 inoculation. The study concluded that systemic resistance in rice against to R. solan could be induced by the strain REB01.
