Ethylene and biotechnology of fruit ripening: pre- and postharvest behaviour of transgenic melons with inhibited ethylene production.

Pre- and postharvest behaviour of transgenic melons (Cucumis melo cantalupensis) expressing an antisense construct of the ACC oxidase gene is reviewed. The transgenic fruit exhibited less than 1% of the maximum ethylene production of the control fruit. Compared to the control, transgenic fruit did not undergo yellowing of the rind and softening of the flesh, but these effects could be reversed entirely with exogenous ethylene. Pigmentation of the flesh occurred before the climacteric and was unaffected by ethylene inhibition. Similarly, total soluble solids content was unaffected. Transgenic fruit failed to develop the abscission zone in the peduncle and remained attached to the plant and accumulated a higher concentration of sugars.
