Abstract
ABSTRACT
Transgenic plum trees (Prunus domestica) containing the plum pox potyvirus coat protein (PPV-CP) gene were inoculated with PPV by aphid feeding or chip budding. Infection was monitored by evaluation of virus symptoms, DAS-ELISA, and immunoblot assays. Based on observations and analyses over 3 years including two dormancy cycles, one out of five transgenic clones (C-5), was found to be resistant to infection whether inoculated by aphids or by chip budding. PPV could not be detected in any inoculated plants of the C-5 clone by immunoblot or immunocap-ture-reverse transcriptase-polymerase chain reaction assays. To our knowledge, this is the first P. domestica clone resistant to PPV infection produced by genetic engineering.
