The main objective of field trial of C5 genetically modified plum resistant to Sharka is to gain further information relating to the agronomical and phenotype performance and compatibility of this event under PPV endemic area and geo-climatic conditions of Romania. The study will be performed in the context of Plum pox virus-free plum crops and decreasing the environmental pollution caused by the abuse of pesticides used for aphids control. [...]
Transgenic plum trees containing the PPV CP gene were tested in experimental orchards under conditions of high PPV inoculum pressure in Spain (notification numbers B/ES/96/16, B/ES/05/14), Poland (ref DOPgmo 4301/02-4/2002), and Romania (import authorization by Ministry of Agriculture no. 1166/ 02/ 1996). Transgenic C5 plum trees were highly resistant to graft-inoculation with PPV and no tree became infected via aphid-mediated transmission of PPV over a 10-year field trials (Malinowski et al., 2006, Zagrai et al., 2006). These data revelead the durability of resistance to PPV of C5 plum trees.
Because the transgenic plums carry the PPV CP gene, the environmental safety issues have been expressed on potential hazards concerning the emergence of PPV variants. The potential impact of transgenic plums expressing PPV CP gene construct on the diversity and dynamics of PPV populations was assessed under open and confined conditions in the frame of a research program sponsored by the European Commission (TRANSVIR QLK3-CT-2002-02140). Across field trials conducted in different locations (Romania and Spain) and environments (continental and Mediterranean), transgenic plums expressing the PPV CP gene had no detectable effect on the emergence of recombinant PPV species over ten years. Also, these transgenic plums had a neutral impact on non-target organisms over extended time (Capote et al., 2006, Zagrai et al., 2006).
Another field trial with C5 transgenic plum is in progress in Czech Republic (notification number B/CZ/06/03).
