| dc.description.abstract | A panel of Citrus tristeza virus (CTV, genus Closterovirus, family Closteroviridae) isolates of different origins and with different biological properties were compared for polymorphisms in the major coat protein (CP) gene by cleavase fragment length polymorphism (CFLP) and single stranded conformation polymorphism (SSCP) analysis. The similarity between the CFLP patterns, which consisted of 15 to 20 bands, was estimated by the Pearson coefficient. The clustering patterns from the CFLP data were very similar to those from sequence data in an experiment with 16 cloned standards of the CP gene. By SSCP analysis on the other hand, most of the clones were not clustered in the same way. To assess the ability of CFLP to analyse biological samples, which may consist of a mixture of genomic variants, the CP gene of 12 CTV isolates was obtained directly from infected plants by immunocapture/RT-PCR and analysed. With few exceptions, the isolates were correctly clustered according to the sequences of the variants composing the isolates. In artificial mixed infections of mild and severe isolates the patterns obtained were more closely related to the severe isolate. Thus the CFLP method was an accurate method for the identification, typing and clustering of CTV isolates. The usefulness of this technique as an alternative to SSCP analysis is suggested and discussed. | |
