引起水稻细菌性穗枯病的Burkholderia glumae的分离鉴定
Isolation and identification of Burkholderia glumae causing bacterial panicle blight of rice
摘要
Abstract
[Aim]The pathogen causing bacterial panicle blight of rice in Xinan Village,Baizhang Town,Minqing County,Fujian Province and its biological characteristics are studied,with the aim of providing guidance for the prevention and control of this dis-ease.[Method]The tissue culture method was employed to isolate the pathogen,the pathogenicity of which was then verified by Koch's postulates.The morphological characteristics,physiological and biochemical properties,and molecular evidence were used to identify the pathogen.[Result]Seven bacterial strains were isolated from rice samples,which were confirmed by Koch's postulates to be the pathogens of bacterial panicle blight.The bacterial strains were gram-negative,forming round and light yellow to earth yellow colonies with smooth edges on NA,KB,PDA,and CCNT plates.The strains showed optimum growth at 34℃and pH7.0.The physiological and biochemical test results of the strains were consistent with those of the control strain Burkholderia glumae GX16.A single target band was obtained by amplification of Bglu3F/R,specific primers of B.glumae.Based on the results above and 16S rDNA,gyrB,and rpoD sequences,the strains were identified as B.glumae.[Conclusion]The pathogenic bacteria causing bacterial panicle blight of rice in Xinan Village,Baizhang Town,Minqing County,Fujian Province is B.glumae.关键词
