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16srDNA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。
A little bitter red wilt occurred seriously in Guangxi planting area. The Koch’s law confirmed that the pathogen was bacteria. The 16srDNA universal primers were used for PCR identification. The sequencing results showed that the PCR products had 99% homology with R. solanacearum. For the first time a little red wilt disease is caused by R. solanacearum.
