| Abstract:
Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus resistance and the relatively rapid incorporation of this trait into Prunus germplasm suggests continued exploration and employment of this strategy for producing virus resistant stone fruits and other woody perennial tree fruits. | |
