The new plant virus family Flexiviridae and assessment of molecular criteria for species demarcation
The new plant virus family Flexiviridae is described. The family is named because its members have flexuous virions and it includes the existing genera Allexivirus, Capillovirus, Carlavirus,…
The family Closteroviridae revised
The mealybug-transmitted species have been separated from the genus Closterovirus and accommodated in a new genus named Ampelovirus (from ampelos, Greek for grapevine), and the family now comprises three genera.
A polymerase chain reaction assay adapted to plum pox potyvirus detection.
Top 10 plant viruses in molecular plant pathology.
A short review on each virus of the Top 10 list and its importance is presented, with the intent of initiating discussion and debate amongst the plant virology community, as well as laying down a benchmark, as it will be interesting to see in future years how perceptions change and which viruses enter and leave the Top10.
Polyvalent detection of fruit tree tricho, capillo and foveaviruses by nested RT-PCR using degenerated and inosine containing primers (PDO RT-PCR).

Recombination was detected or suspected in 18 out of 109 potyvirus isolates tested, belonging to four out of eight virus species, and was most prevalent in potato virus Y, clear in bean common mosaic virus, and possible in bean yellow mosaic and zucchini yellow mosaic viruses.
Geographically and temporally distant natural recombinant isolates of Plum pox virus (PPV) are genetically very similar and form a unique PPV subgroup.
Results indicate that recombinant isolates represent an evolutionarily successful, homogeneous group of isolate with a common history and unique founding recombination event, and the name PPV-Rec is proposed for this coherent ensemble of isolates.
Plum pox virus and sharka: a model potyvirus and a major disease.
Different genetic engineering approaches are being used to generate resistance to PPV, and a transgenic plum, 'HoneySweet', transformed with the viral CP gene, has demonstrated high resistance toPPV in field tests in several countries and has obtained regulatory approval in the USA.
