Now he fears that tree and fruit quarantines across the Niagara River borders may shut down his plan, even if he does not find PPV on his farm. Similarly, Ernest Borchert and Vito Truncali of Marlboro, NY, imported plum trees from an Ontario nursery to allow them to expand their fresh fruit sales into NY city green markets. They fear that they might have unknowingly imported plum pox into their Hudson River Valley farming district. Howard Lewin of Calverton, NY on LI has planted over 50 acres of new peaches in the past few years to diversify his farm's income. So the PPV worry is from one end of the state to the other.
Genetic solutions are the primary control strategy for plum pox if eradication attempts fail.
I'll be brief, because I am not professionally trained in genetic engineering. Although I, as a traditional breeding methods practitioner, am trained to understand the genetic research goals of both traditional and genetic engineering. My world class virology research colleague, Dr. Dennis Gonsalves is active in plum pox virus research. He collaborates with USDA, ARS scientists at Kearneysville, WV, where they created the 'C5' strain of European plum which carries on its chromosomes the genetic information that transcribes for making protein coats of plum pox virus. They inserted this into its chromosomes via commonly employed transformation techniques.
