Passionfruit ringspot virus isolated from Adenia lobata in lvory Coast
Introduction
During a study on passionfruit viruses in Ivory Coast, a survey for wild Passifloraceae in the neighbourhood of the ORSTOM, revealed that Adenia lobata was very often present in the forest border. Plants showing mosaic symptoms in their leaves were first found in 1970. Check inoculations on Passiflora edulis var. flavicarpa and P.foetida caused the same symptoms in these test plants as passionfruit ringspot virus (PRV) did (De Wijs, 1974). A. lobata plants with less obvious symptoms and even without symptoms gave the same reaction. One plant was chosen for further identification of the virus involved. From the beginning of the study PRV was used for comparison with the Adenia virus (AV).
Conclusion
No major differences were found in host range, aphid transmission, particle form and length and serology between the two isolates. The virus isolated from A. lobata is therefore considered as being passionfruit ringspot virus (PRV) (De Wijs, 1974).
