| Abstract: | Special primers for Citrus Huanglongbing pathogen 16S rDNA gene was designed to establish a PCR detection technology of Citrus Huanglongbing.The effects of the main ingredients of PCR on the reaction was examined,and so established the optimized PCR detection system.Using PCR detection system,plant samples and Virus-Eliminated Seedlings were detected.Studies indicated that the described method,with the advantage of economy,high speed,sensitivity and stable reproductivity,can be effectively applied to detect infected citrus trees of the various cultivars and to screen large numbers of disease-free seedlings. |
