摘要：
The genotypes of ten citrus tristeza virus (CTV) isolates from central China were determined by examining multiple molecular markers (MMMs) using 11 primer pairs. The results revealed that one isolate contained a single T30 genotype, two isolates contained a single VT genotype, and the other seven isolates were mixtures of two or more genotypes. Sequence analysis of amplified MMMs showed a high genetic diversity in Chinese CTV populations. The genotypes resembling T36, RB and B165 were identified from Chinese CTV isolates for the first time. Our results suggest that genotype assignment of CTV cannot be based solely on the amplification profiles of MMMs, and sequencing of MMMs is required.
