Yes (MAFF 1990); Citrus mosaic strain of this virus has been reported only from Japan and is widespread and increasing in importance there (EPPO 2005).
No (EPPO 2005)
Yes – Graft transmitted disease. The citrus mosaic strain of this virus produces symptoms on fruits. On satsumas, these are green blotches or ring shaped spots on the rind at colour break and delayed colouring of the spotted area (MAFF 1990; Iwanami and Koizumi 2000; EPPO 2005).
Yes – Graft transmissible (Vernière et al. 2004). Therefore if the plant is infected the viroid may enter the fruit via phloem.
Hop stunt viroid
Yes (Shikata 1990)
Yes (CAB International 2004).
Not present in WA (DAWA 2003b).
Yes – Graft-transmitted (Duran-Vila et al. 2000a). Therefore although generally associated with leaves (Momma and Takahashi 1982; Roy and Ramachandran 2003) the viroid may enter the fruit via phloem. The citrus type Hop stunt viroid has been isolated from the fruit peel of Etrog citron (Shikata 1990).
