Citrus tatter leaf capillovirus should be considered as an isolate of apple stem grooving capillovirus
Citrus tatter leaf capillovirus (EPPO A1 quarantine pest) affects citrus but a similar virus has also been isolated from stunted and chlorotic lilies. In previous studies, it has been found that the virus from lily cannot be distinguished from apple stem grooving capillovirus (isolated from apple), on the basis of biological or serological properties or genome organization. Studies were carried out in Japan on the relationships between apple stem grooving capillovirus (ASGV) isolated from various rosaceous fruit trees (apple, European and Japanese pears) and citrus tatter leaf capillovirus (CTLV) from citrus trees, by comparing their genomes. The results provided further evidence that CTLV from citrus cannot be distinguished from ASGV, based on the nucleotide sequences of the genomes. The authors noted that this supports the proposal that CTLV should be regarded as an isolate of ASGV. ASGV is not an EPPO A1 quarantine pest, and occurs in many European countries.
