| 摘 要： | 根据植物菌原体１６ＳｒＲＮＡ基因序列，合成一对寡核苷酸引物，用ＳＤＳ ＣＴＡＢ改进法直接提取田间发病的柿树带化病、刺槐丛枝病树和健康树皮层的ＤＮＡ，用ＰＣＲ方法成功地从病树ＤＮＡ模板中扩增出约１．１７ｋｂ的特异产物，经酶切进一步证实为植物菌原体１６ＳｒＤＮＡ．此项研究表明用特异合成的引物Ｆ１６／Ｒ１６，经ＰＣＲ扩增可以快速灵敏地检测植物菌原体． |

| Abstract: | A pair of oligonucleotide primers was designed on the basis of Phytoplasmas 16SrRNA gene sequences. Total DNA was extracted from persimmon fasciation, black locust witches' broom and their healthy plant tissues collected from fields using amended SDSCTAB method. PCR products at the length of 1.17kb amplified from phytoplasmainfected tissues DNA were confirmed as Phytoplasmas 16SrDNA. This research indicated that Phytoplasmas could be inspected rapidly and sensitively by Polymerase Chain Reaction (PCR) with a specific primer pair F16/R16.= |
