PMTV (Potato Mop-Top Virus ) and PAMV Aucuba Mosaic Virus) are new damaging pathogens of potato crop in Romania. They can cause serious reduced yield decrease the tuber’s quality. In case these viruses, infected plants do not allways show signs disease symptoms depend on cultivar, virus strain environment. infection material produce spraing tubers sensitive varieties. causes heavy losses northe...

The cysteine-rich 8K protein of Potato mop-top virus (PMTV) suppresses host RNA silencing. In this study, evolutionary analysisof 8K sequences of PMTV isolates was studied on the basis of nucleotide and amino acid sequences. Twenty-one positively selected sites were identified in 8K codingregions. Recombination events were found in the 8K of PMTV isolates with a rate of 1.8. Totally 30 haplotyp...
