Genetic engineering of Plum pox virus resistance: 'HoneySweet' plum-from concept to product por Scorza, Ralph, Callahan, Ann, Dardick, Chris, Ravelonandro, Michel, Polak, Jaroslav, Malinowski, Tadeusz, Zagrai, Ioan, Cambra, Mariano, Kamenova, Ivanka

“…Sharka disease, caused by Plum pox virus (PPV) was first recorded in Bulgaria during the early twentieth century and since that first report, the disease has progressively spread throughout Europe and more recently to Asia, Africa, North and South America. Few PPV resistance genes have been found to naturally occur in Prunus and this has led to the investigation of biotech approaches to the development of resistance through genetic engineering (GE). …”
