The APHIS database entry for the release describes the GM plum as modified for PRS (papaya ringspot) virus resistant, carrying a visual marker. The more detailed Environmental Assessment describes both papaya ringspot as well as plum pox virus as well as the introduction of both the visual marker beta-glucosidase as well as kanamycin resistance (nptII). The assessment goes into detail about 'cross protection' and whythe PRS coat protein could lead to a successful protection against PPV.
" The heterologous protection may be important because a broad multivalent resistance would enable plants to be protected against many potyviruses by using a limited number of different coat protein genes (Stark and Beachy, 1989). This broad multivalent protection is basis of expressing papaya ringspot virus coat protein in the trees instead of plum pox virus. PPV and PRSV coat proteins do share significant homology although there are other potyviruses are more closely PPV than PRSV (Ward and Shukla, 1991)." (EA)
The APHIS database then links to the petition data describing plum pox virus resistant plum - the same petition data that is also linked by the permit # 95-205-02R.
Currently it remains unlcear whether the GM event in this release is C5.
