true consumption levels, since some level of CP degradation
would be expected under normal food preparation conditions. By
comparison to the levels measured in fruit, transgene-derived CP
generally accumulates to higher levels in the leaves, at least in
transgenic papaya line 55-1, which thus allowed for the detection
of the CP in the leaves of SunUp. Similar to the relative
differences in CP levels observed between the fruit, the amount
of CP accumulating in the leaves of SunUp was measured to be
1.9 times lower than that found in the leaves of Rainbow. The
amount of CP accumulating in the leaves of Rainbow, in turn, was
13.9-fold lower than that of the leaves of PRSV-infected non-
transgenic papaya plants
