摘要
应用PCR-SSCP技术对我国柑桔主要产区、泰国和法国留尼湾等地收集到的柑桔黄龙病亚洲种病原(Candidatus Liberobacter asiaticus)16S rDNA进行了分析。PCR结果表明,不同的地区的柑桔黄龙病亚洲种16S rDNA在长度上没有明显区别。进一步的SSCP结果显示,不同地区柑桔黄龙病亚洲种16S rDNA序列在组成上也没有差异。显示来自不同地区、不同寄主品种的柑桔黄龙病亚洲种种内没有存在明显差异。
PCR- SSCP was used to analyze the citrus Huanglongbing pathogen＇s 16S rDNA. The pathogens were collected from China, Thailand and Reunion, France. Based on the PCR analysis, all pathogen samples showed a consistent length of 16S rDNA. Further study by SSCP also found no difference in 16S rDNA structure. Thus it was confirmed that the Candidatus Liberobacter asiaticus on the citrus varieties had identical 16S rDNA.
