Papaya leaf distortion mosaic virus (PLDMV)
The virus causes a destructive disease of papaya in Asia. The symptoms are similar to the related Papaya ringspot virus (PRSV), that means leaves and fruits are distorted and discolored, and are accompanied by thin stems. Cultivars resistant to PRSV are, however, not resistant to PLDMV. In fact no papaya cultivars resistant to PLDMV are known. The virus is easily transmitted by aphids. The genome contains 10,153 nucleotides excluding the 3′-poly (A) tail and is translated into a polyprotein.
