摘要: |
一点红青枯病在广西种植区严重发生。通过柯赫氏法则证实病原菌为细菌。用16s rDNA通用引物进行PCR鉴定,测序结果表明,PCR产物与茄青枯菌有99%的同源性。首次报道一点红青枯病由茄青枯菌引起。 |

Abstract: |
Emilia sonchifolia bacterial wilt was severely occurred in the field in Guangxi,China. The pathogenic bacterium was confirmed by Koch postulate. Then Polymerase chain reaction(PCR)amplification was conducted using 16s rDNA universal primers to identify the pathogenic bacterium. PCR products sequencing results showed the pathogenic bacterium had 99% homology to Ralstonia solanacearum. This is the first report of E.sonchifolia wilt caused by R.solanacearum. |
Key words: Emilia sonchifolia wilt Ralstonia solanacearum |
