Transgenic melon analysis. Technician freezes the flesh of genetically engineered (transgenic) melon fruit for later analysis. The flesh is frozen in liquid nitrogen; a whole transgenic melon is seen. This plant contains a gene that delays the ripening of melon fruit. Melon fruit normally ripens in 3-4 days and must be sold 4 days thereafter before it rots. Ethylene gas naturally emitted by the fruit causes its own ripening. The transplanted gene reduces ACC-oxidase and blocks the ethylene gas pathway of ripening. Transgenic melon fruit thus keep for 50 days without rotting while fresh taste and smell is maintained. Research at E.N.S.A.T. in Toulouse, France.
